Network Wall Speaker

• A well-balanced, all-in-one network wall-mounted speaker with a medium-gray wood casing and iron mesh.
• It runs on Linux, ensuring stable performance and fast operation.
• It employs a DSP software audio decoding solution to achieve networked transmission of 16-bit stereo CD-quality audio signals.
• It features a built-in Class D stereo 2×30W amplifier circuit, delivering delicate sound quality and powerful output.
• It utilizes a 6.5-inch mid-bass driver and a 1.5-inch tweeter to provide clear speech reproduction.
• It includes one RCA input and one 6.5mm microphone input with independent volume control.
• Network volume can be locally adjusted.
• It has one audio power output for connecting one 30W constant impedance 8-ohm speaker.
• It features active takeover functionality in case of network or server disconnection, enabling automatic playback when the terminal is disconnected.
• It has 4GB of built-in memory, and programs can be transferred to an SD card for storage via the network.
• Built-in high-precision digital clock chip with a power outage timekeeping period of at least 3 years and network time synchronization function;
• Built-in analog audio signal backup module, supporting constant voltage 100V signal input;
• When the device detects no network signal input or power failure, it automatically switches to constant voltage signal amplification, achieving dual-line redundancy;
• Receives platform commands and audio signals, supporting remote volume control by the platform;
• Supports platform permission settings and management for the device;
• Supports status feedback, allowing the device's playback and working status to be transmitted back to the platform;
• Supports platform permission settings and management for the device;
• Supports platform remote upgrade function for the device;
• Supports platform zone and group broadcasting function for the device;
• The device power supply adopts a switching power supply design, capable of operating normally with AC100~240V voltage;
• Supports 15KV ESD protection and has a built-in network isolation surge protection circuit;
• 1 PC serial port (expandable with custom interfaces);
• A digital networked product, easy to expand, not limited by geographical location, and requires no additional data center management equipment;
