MAG6825F 4×250W Four-Channel Network Digital Amplifier

Features

● With time frame synchronization mechanism, the local clock and the network host clock are synchronized in real time;
● The front panel integrates four groups of status indicators, each group consisting of five LEDs: Net, Timing, Signal, CLIP, and PROT.
● Supports network audio playback, capable of playing program sources distributed by the network host or audio streams from network audio collectors.
● It can play background music, emergency paging and alarm signals from the system host, which can be divided into three categories: background broadcasting, business broadcasting and emergency broadcasting;
● Built-in watchdog function, effectively ensuring the normal operation of equipment;
● Adopts a high-fidelity CD-quality decoding chip, supporting decoding of MP3/WMA/WAV/PCM audio stream data with a maximum sampling rate of 48kHz and 16-bit resolution.
● The self-developed real-time operating system has strong real-time performance, and the broadcast sounds of multiple network players are synchronized in real time, and there is basically no time difference between them.
● Adopt self-developed network data error correction algorithm to ensure the real-time transmission of data and the accuracy of received data, ensuring stable and reliable operation.
● Built-in offline local scheduled playback function, scheduled program backup is stored in the SD card, and scheduled program is fully automatically backed up;
● Provides four AUX line inputs/outputs and four MIC inputs/outputs for convenient local audio source expansion and power extension.
● MIC input sensitivity switchable between 5mV and 100mV, compatible with passive, wireless, or active microphones.
● Supports 100V constant-voltage output (two terminals of the 8-pin 7.62mm barrier terminal block.)
● Supports 100V constant-voltage backup (two terminals of the 8-pin 7.62mm barrier terminal block.)
● Equipped with four RJ45 network ports (no hand-in-hand connection supported).
● Through the WEB page, network configuration, password login, and system settings can be performed, including: language setting (Chinese and English optional), login setting, offline scheduled playback function setting, amplifier standby mode setting, 100V constant-voltage backup function setting, and audio source priority setting (AUX, MIC, and Network are the three types of audio sources. When the priority levels are set the same, the output will be mixed, without mix level adjustment. By default, the lower-priority audio source is muted.)

  • Introduction
  • Specification

The four-channel network digital power amplifier is a fully digital signal processing amplifier based on the TCP/IP transmission protocol. It can connect to any network switch and features network line fault detection and automatic switching to ensure higher reliability. The device adopts a silver anodized aluminum alloy front panel, an industrial-grade gray iron chassis, and a 2U rack-mount design.
