Features:

Standard rack mounted, 2U height; Advanced aluminum panel with advanced polishing

Using a fixed static IP address, the address will not be lost when the network changes, ensuring stable operation

Designed using embedded PC technology and DSP audio processing technology; Built in embedded network voice decoding module, completes synchronous reception and decoding of network audio streams

Adopting high-speed industrial grade ARM chips, the startup time reaches millisecond level; Improve the stability of device usage

Provide automatic and manual forced power switch buttons

One or four network signal inputs, one or four stereo audio signal outputs

High quality digital audio transmission, noise free, with CD level sound quality (adaptive audio file bit rate of 32-320kbps)

Two or four power supply control (220V), maximum withstand power 2000W; automatic control of external power amplifier equipment power supply; Power management supports pre turn on function

Equipped with a short-circuit triggering interface, it is easy to trigger and control other devices

Equipped with intelligent power management function, the device uses a built-in CPU to determine the operating status of the amplifier. When there is no working state, the amplifier automatically enters a sleep state with a standby power of ≤ 0.2W. When there is a playback task, the amplifier automatically starts up

Equipped with remote volume adjustment function, the terminal automatically adjusts the volume to the default state set by the system when starting and playing tasks automatically. Automatic volume adjustment default value

The machine is equipped with an IP address reset switch, which can restore the factory settings after resetting
