Peacock AV System FAQ

Deeply optimized system software for the Kongque all-in-one PC delivers maximum stability and full functionality. Third-party audio devices may be compatible, but they require strict adherence to hardware specifications, OS versions, impedance, and power ratings. Mismatched parameters can lead to no sound, lag, crashes, or hardware damage; on-site technical evaluation is required for compatibility assessment.

Ohms (Ω) denote the nominal impedance of a speaker, indicating its load response standard for amplifiers. 4 ohm speakers deliver powerful bursts and deep bass impact but demand extremely high current from the amplifier; prolonged high-volume use can trigger thermal protection or damage the unit. 8 ohm speakers offer lower load, reduced heat generation, and superior stability, supporting all-day continuous operation—making them the standard choice for commercial venues.

For commercial venues that operate for extended hours, such as restaurants, hotels, and foot baths, always prioritize 8Ω speakers. 4Ω speakers are only suitable for short-duration stage bursts and are not designed for continuous operation in retail environments; their stability and durability do not meet commercial requirements.

Do not mix speakers with different impedances. Doing so causes load imbalance, uneven volume, and phase issues, which can easily damage tweeters and the amplifier's mainboard. This is strictly prohibited in commercial installations.

Not compatible. Compatibility with 4-8Ω indicates the amplifier can only tolerate a minimum 4-ohm load for short durations, not for continuous operation. If your system's rated impedance is 8Ω, do not connect 4-ohm speakers, as this will cause immediate overload and damage. For commercial applications, always match the equipment to its rated impedance.

Two 8-ohm speakers in parallel result in a total impedance of 4 ohms. For commercial multi-speaker installations, always calculate the total load impedance beforehand. Never allow the total impedance to fall below the amplifier's minimum supported threshold to prevent overheating, protection activation, or component failure.

Home audio and commercial equipment follow entirely different design logics and cannot be adapted for retail operations: ① Battery life: Home devices support only short-term use, while commercial units operate continuously for 12–18 hours; ② Environment fit: Home speakers prioritize intimate home listening experiences, whereas commercial systems are optimized for noisy environments to enhance vocal clarity and projection; ③ Durability: Commercial units feature dustproofing, oil-fume resistance, and anti-aging treatments tailored to complex store conditions; ④ Feature suite: Commercial systems include full business capabilities like screen casting, QR code song selection, backend maintenance, and license management—home speakers lack any intelligent operational support.

Home appliances often list inflated peak power, which only represents an instantaneous limit and has no practical reference value. Commercial devices uniformly specify rated RMS continuous power, reflecting long-term stable output capability. Since the two use different standards, they cannot be directly compared.

Not a viable substitute. Home KTV systems only support basic karaoke playback and lack essential commercial features such as smart screen casting, QR code song selection, remote maintenance, license management, expiration alerts, and chain-store control. Their hardware is not built to withstand long-term high-load operation in commercial settings, failing to meet the stability and functionality standards required for business use.

The two are tuned differently. Home HiFi prioritizes refined, faithful sound in quiet environments, while commercial audio optimizes for vocal clarity, even sound distribution, and long-term stability in noisy settings. In real-world retail scenarios, commercial equipment delivers a far superior experience than home devices.

Not commercially viable. Such ultra-high power claims are manufacturer-stated exaggerations without unified testing standards or verified data—pure marketing hype. Peak power lasts only milliseconds and cannot sustain operation. Commercial selection must be based on rated RMS continuous power.

False. Most low-cost devices on the market feature numerous decorative fake speakers that are purely plastic shells with no diaphragm, wiring, or sound output—they serve only as aesthetic enhancements. Sound quality depends on driver quality, enclosure design, professional tuning, and impedance matching, not speaker count. Blindly adding cheap small drivers can actually degrade audio performance by causing chaotic sound staging and poor clarity.

You can quickly identify them using three methods: ① Press test: The genuine speaker diaphragm is flexible and can be slightly pressed, while the fake one is made of hard plastic and cannot be pressed. ② Vibration test: When playing music, the genuine speaker vibrates noticeably, whereas the fake one shows no vibration. ③ Wiring test: After opening the unit, the fake speaker has no connecting wires or crossover connections.

Peak Power (PMPO) represents a device's instantaneous power surge, lasting only moments and unsuitable for stable operation; it is frequently exaggerated in the market. Rated RMS power is the effective power a device can deliver continuously and reliably—the true metric for commercial audio performance. We focus on commercial stability and commit to listing only genuine rated power, eliminating false advertising.

Significant discrepancy. The actual rated power of peak 200W devices is typically only 40-60W; an RMS rating of 200W represents genuine, long-term stable output and is the key criterion for commercial procurement.

Not recommended. Legitimate commercial devices clearly specify their rated RMS continuous power. Deliberately omitting rated parameters while exaggerating peak values is a marketing tactic used to conceal the device's true performance.

Not necessarily. Actual volume is determined by rated power, speaker sensitivity, enclosure design, and impedance matching. Inflated peak power figures have no practical value. Even with sufficient power, impedance mismatches can cause muddy sound quality and damage equipment.

Large low-frequency drivers deliver richer bass, while multiple small drivers ensure more uniform vocal dispersion. Commercial private rooms don't need to compete on speaker count; prioritize integrated systems that feature professional full-unit tuning and scene-specific optimization.

Supports local network casting. The device also features a built-in hotspot, allowing phones to connect directly for casting without an external internet connection.

Quick fix using standard steps: Connect to 5GWiFi first to avoid 2 4G band interference, disable simultaneous screen casting on multiple devices, lower the casting resolution, and restart the device system for smooth performance.

Users can scan to request songs, skip tracks, adjust volume, and play/pause. Administrators can scan to quickly access the simplified backend management interface for easy operations.

Local music playback and offline casting work without an internet connection. Cloud library loading, authorization verification, and background statistics require a network connection.

Fully compatible with Apple AirPlay and DLNA casting protocols. Supports screen casting from iPhones, Android devices, and Windows PCs. Legacy devices without built-in casting support can be enabled via external hardware adapters.

Normal online upgrades preserve critical data such as tuning parameters and system settings. Do not power off the device during the upgrade to ensure a smooth update process.

Hardware devices can be purchased outright; the software system uses an annual subscription model. The standard fee is 198 CNY/year, activated manually via the backend. Online self-service renewal is not yet supported.

The system features an intelligent expiration alert mechanism that sends notifications 15 days in advance. The admin dashboard displays the remaining usage days and exact expiration date in real time, enabling merchants to renew or maintain services proactively.

After expiration, the cloud library and premium marketing features will be locked, and basic playback will be restricted. Renew now to restore full access.

Not supported. Licenses are uniquely bound to device serial numbers on a one-to-one basis, meaning each device requires its own license and sharing or reuse is not allowed.

Yes. Contact your operations team to provide the old and new device serial numbers to complete the license transfer.

The longer the cable run, the thicker the gauge of speaker wire required. Thin or long cables cause volume loss and degraded sound quality, while also altering equipment load impedance, which can lead to device failure.

Don't base your setup on speaker count; focus on the total system impedance. Never let the total impedance drop below the amplifier's minimum supported threshold, and avoid blindly connecting multiple devices in parallel.

Install the device away from areas directly exposed to stove fumes. Perform regular dust cleaning and maintenance. Fumes accelerate speaker unit aging, cause dust accumulation and degradation, and significantly shorten the device's lifespan.

The Standard Edition is an indoor commercial unit. It is not waterproof and cannot be used outdoors in rain; a custom waterproof version is required for outdoor applications.

This all-in-one unit features factory-sealed amplifier and speaker wiring, eliminating the need for manual disassembly. Follow these steps to troubleshoot: check if the device is muted or volume is too low; verify correct audio source channel selection; confirm software license validity; restart the device to resolve temporary system glitches.

Public networks in venues like restaurants and foot massage parlors often suffer from insufficient bandwidth and severe interference. Standard troubleshooting: disconnect the store's existing network and connect devices to a personal mobile hotspot for testing. If all features work normally on the hotspot, the issue lies with the store network, not the device. For long-term use, we recommend configuring a dedicated WiFi connection.

Root cause: Microphone frequency collision. Solution: Assign each device an independent frequency to ensure no two rooms share the same frequency. After moving a device or replacing a microphone, re-tune the frequency immediately to prevent audio interference.

Commercial Booth Tuning Core Principle: Vocal volume must exceed background music by 20%–30%. Standard Calibration Guidelines: Slightly boost high frequencies and reduce excessive bass to ensure clear, transparent vocals; apply reverb and delay judiciously to refine vocal imperfections without creating an empty or hollow sound. If feedback occurs, immediately adjust microphone volume and reverb settings to avoid acoustic resonance points.

The device supports three convenient commercial karaoke modes: remote song selection via mobile QR code scan, direct touch selection on the unit's screen, and hands-free voice control. Designed to meet diverse usage scenarios.

Audio-visual performance is independent of device hardware and reflects industry-standard source characteristics: ① To support instant playback for commercial use, the cloud library compresses video sources to ensure fast loading even on slow networks; ② Many classic older songs originate from decade-old VCD sources with inherently lower resolution and audio quality, further degraded by repeated copying and compression; ③ To verify your device's true audio-video capabilities, play the latest high-definition official music videos—this will clearly demonstrate the device's actual HD performance.

Supports connection of third-party microphones. However, since these devices have not been professionally tuned and adapted by the manufacturer, you may experience differences in microphone sensitivity, noise cancellation, and vocal clarity, resulting in a suboptimal singing experience. For commercial or long-term use, we recommend using an officially supported microphone.

Fully compatible with all display devices. Features a standard HDMI high-definition output port for direct connection to smart TVs, legacy non-smart TVs, and commercial LED screens. Supports screen expansion up to 200-300 inches with plug-and-play convenience—no modifications required.

Hardware complies with China's mandatory "Three Guarantees" regulations, offering a one-year free warranty and lifetime repair support. Software after-sales service ensures rapid response: routine issues are resolved within 24 hours, while complex problems receive a complete solution and implementation plan within 48 hours.

Supports full-chain management. The headquarters' central backend allows remote monitoring of all store devices, including operational status, license expiration details, and system configuration parameters, enabling batch maintenance, unified control, and remote administration.

All audio and video library resources in the system are licensed for commercial use with full compliance. They are safe for operational use in retail locations, with no copyright risks.

Core device settings, audio tuning parameters, and system configurations are permanently retained and will not be lost. The system includes an intelligent cleanup mechanism: temporary content such as user-uploaded videos, images, and custom welcome messages is automatically cleared daily at 14:00 and 24:00. This prevents residual content from previous customers and ensures a clean, consistent experience for the next guest.

Unreliable. The core of procurement lies in distinguishing between inflated peak power and true rated RMS power, while rigorously verifying impedance matching, device sensitivity, and scenario compatibility to avoid parameter misrepresentation traps.

Minor issues include weak sound, low volume, or muddy and unbalanced audio quality. Severe issues involve amplifier overheating protection, automatic shutdown, or immediate damage to the amplifier or speaker drivers.

Do not blindly parallel speakers; calculate the total impedance in advance. Plan the store LAN rationally to avoid IP conflicts. Reserve space for device maintenance and operations to facilitate future upkeep.

Integration is possible but requires prior verification of legacy device impedance, power rating, and system version. Mismatched parameters can easily cause equipment damage; we recommend an on-site technician assessment for compatibility.

Traditional card-based PA systems are professional KTV equipment with acceptable audio quality but are unsuitable for restaurant operations: ① Fixed and immovable: Once ceiling-mounted, their position is permanent, making them incompatible with flexible scenarios like private banquets, temporary venue changes, or open seating areas; ② Extremely high maintenance threshold: Restaurants lack professional sound engineers. If guests adjust settings incorrectly or feedback distortion occurs, the issue cannot be resolved on-site, often rendering the equipment useless; ③ Poor scenario adaptation: Tuned specifically for enclosed KTV booths, they fail to provide uniform sound coverage in open dining halls. The Kongque All-in-One system is purpose-built for restaurants. It supports full mobility for versatile use across all scenarios. With pre-configured commercial audio parameters built-in, it requires no professional tuning—enabling zero-threshold maintenance and delivering even sound coverage tailored to open dining environments.

Standard portable PA speakers are designed only for outdoor, temporary entertainment and fail to meet commercial retail standards: ① Poor acoustic experience: Low-level floor placement creates a mismatch with seated or standing singing/listening angles, resulting in muffled vocals and a fragmented soundstage. ② Limited expandability: Built-in small screens look basic; while external TV connection is possible, there's no integrated smart casting or on-demand system—functionality remains minimal. ③ Low-end store image: Cheap, rough appearance significantly detracts from the store's interior design quality. ④ Missing commercial features: Lacks backend operations, authorization management, chain-store control, and automatic purification mechanisms—unable to support daily business operations. The Kongque All-in-One unit is engineered to match natural human listening heights, delivering rich, clear acoustics. It supports ultra-large LED screen expansion, boasts a premium commercial aesthetic, and includes a complete commercial software operations suite—fully tailored for high-quality dining venue management.

Based on the core principles of safety, stability, and cost-effectiveness for commercial public spaces, we have opted against a battery-powered version: 1. **High Safety Risk:** All lithium batteries carry risks of aging, swelling, overheating, and spontaneous combustion. In environments with heavy foot traffic, continuous power supply, and no real-time monitoring, these hazards are uncontrollable. An incident would result in significant losses. 2. **Contradicts Design Intent:** Built-in batteries significantly increase device weight, making it cumbersome to move and compromising the all-in-one unit's core advantage of flexible mobility. 3. **Poor Cost-Effectiveness:** Battery modules drastically raise procurement costs and introduce ongoing maintenance expenses due to degradation and replacement cycles. Since commercial stores operate with fixed power connections, batteries are an unnecessary addition. For commercial settings, a wired, non-battery design offers a safer, more stable, and more professional solution.

The main reason most stores choose the wrong equipment: they focus only on audio specs, ignoring scene compatibility. Karaoke systems are professional but rigid and hard to maintain; square dance speakers are cheap but low-end with poor user experience; home audio units can't handle commercial long-term operation or harsh environments. For restaurants, the ideal choice is an all-in-one AV solution that offers: custom-tailored for your scene, no pro setup needed, easy mobility, large screen expansion support, reliable safety, and a complete commercial maintenance system.

Conference room audio pricing depends on room size, ceiling or wall-mount installation, number of microphones, and whether screen projection integration is required. For small to medium rooms (30-60 sqm), the standard setup includes professional speakers, a DSP amplifier, wireless microphones, and a conference display, with total costs typically ranging from tens of thousands of yuan. Large auditoriums require additional line array sound reinforcement and an audio processor. Local projects in Suzhou offer on-site surveys to provide accurate quotes, ensuring you don't overpay for inflated specifications.

The core of pairing commercial KTV with dining booths comes down to three points: first, select commercial speakers with a 8Ω rated impedance and genuine RMS power rating to ensure stable operation over long periods; second, set vocal volume 1%-30% higher than the backing track, slightly brighten the highs while controlling the lows for clear vocals; third, assign each booth its own microphone frequency to prevent cross-talk. For dining booths, opt for all-in-one karaoke speaker systems that require no professional setup and offer zero-maintenance operations.

When installing indoor LED large screens, keep four key points in mind: First, calculate the load-bearing capacity of the wall or steel structure in advance and reserve space for maintenance access and heat dissipation. Second, route power and signal cables separately to avoid interference from long-distance parallel runs with high-voltage lines. Third, select the pixel pitch based on viewing distance: P1.5-P2.5 is common for conference rooms, while P2.5-P3 suits lobbies. Fourth, after installation, perform full-screen color calibration and brightness uniformity adjustments. Local engineering support in Suzhou includes on-site surveys, design, and construction.

Though they share similar hardware form factors, their software and use cases differ. Teaching all-in-one PCs focus on multimedia instruction, featuring interactive whiteboard writing, subject-specific tools, lesson recording, and class management systems, with interfaces adapted for document cameras and other teaching aids. Conference tablets prioritize office collaboration, emphasizing wireless screen sharing, two-way annotation, video conferencing, and file management. Choose a teaching all-in-one PC for school multimedia classrooms and a conference tablet for corporate meeting rooms; consult technical staff for configuration recommendations based on your venue's intended use before purchasing.

When selecting a commercial digital signage player, consider three key dimensions: 1) Installation method: choose freestanding units for store entrances; wall-mounted or ceiling-mounted options work best at checkout counters and open kitchens. 2) Brightness and screen: high-brightness displays are essential for street-facing windows, while standard 500nit screens suffice for indoor use. 3) Management approach: for chain stores, select models with cloud-based content scheduling that enable remote publishing, playback control, and scheduled power on/off. In open kitchen settings, pair the display with an electronic menu board to ensure real-time price and dish updates.

The standard process consists of five steps: on-site acoustic survey → equipment list and cabling plan proposal → quote confirmation and contract signing → equipment delivery, installation, and commissioning → acceptance training and after-sales record creation. The quote comprises three components: equipment costs, cable and accessory costs, and labor installation fees. A professional quote specifies the equipment's rated RMS power and impedance; it avoids inflating prices by citing exaggerated peak power figures. On-site surveys are available for projects in Wujiang, Kunshan, Changshu, Zhangjiagang, and other areas within Suzhou.

Commercial selection should focus on four key specs, not brand hype: rated RMS continuous power (avoid peak-power marketing claims), nominal impedance and amplifier matching (prioritize 8Ω for commercial venues), sensitivity and sound coverage (choose models with strong vocal clarity for noisy environments), and environmental resistance (dust and grease protection). For long-operating scenarios like restaurants and foot spas, use all-day-rated commercial integrated systems—do not substitute with consumer-grade audio equipment.

Restaurant mobile speaker placement follows three principles: 1) Align speaker height with seated and standing ear levels to prevent muffled vocals from low floor placement. 2) Distribute speakers evenly across the banquet hall; position main speakers toward VIP areas and add fill speakers for corner tables. 3) Keep speakers away from kitchen exhaust fumes and air vents, and clean them regularly to extend lifespan. For mobile events, choose all-in-one units with built-in batteries—ready in 10 minutes upon arrival.

Designed for minimal setup: creating welcome greetings is entirely a selection-based process. After choosing the banquet type, title, and name, the system auto-generates the greeting and displays it on screen. Staff simply confirm to show it—no typing required. New hires can get started in minutes.

No. Guests can upload materials anonymously without registration or login. The system automatically clears guest anonymous content daily at 14:00 and 22:00, retaining only store-owned content. Guest photos and videos are not stored on the store's devices.

Cached images, videos, and background music on your device can continue to play offline. Cloud-based content loading, QR code scanning uploads, AI-generated greeting messages, and remote mass messaging require an internet connection; they will automatically sync once the network is restored.

Chain brands can centrally bind and manage multi-store devices via the merchant admin portal. Send images, videos, and text notifications by store or across the entire chain. Schedule ad tasks remotely, monitor device status, and perform updates—all from a single dashboard that gives headquarters full visibility of every store screen.
