AMP 88AU

AMP-88AU is a 1U rack-mounted audio and video display all-in-one device, utilizing the AES67 network audio transmission protocol and supporting the input and output of 8 analog channels + 8 network audio channels. The device integrates automatic audio mixing and GPIO control functions, efficiently meeting the needs of multi-node audio mixing processing. Equipped with HDMI interfaces, it supports 2-out-of-1 signal source switching and audio-video separation. The body is equipped with two multifunction buttons, supporting IP display switching, mute control, phantom power on/off, long-press reset, and other operations.

Functional features：

1.Sampling rate is 48kHz.

2.High-performance AD/DA, low distortion, wide dynamic range, and pure sound quality.

3.Network connection, efficient and concise operation interface software that is easy to use in engineering, enabling real-time control of all functions and monitoring of machine working status.

4.Supports UAC (TYPE B) and USB AUDIO (TYPE C).

5.8-channel MIC/LINE input, 8-channel balanced output.

6.8-channel AES67 network input, 8-channel AES67 network output.

7.2 HDMI inputs and 1 HDMI output.

8.2 multi-function buttons (support IP switching, mute, and long press to reset to factory settings).

9.4-channel automatic mixing; 1-channel echo cancellation.

10.2 Gigabit Ethernet ports, each capable of simultaneously transmitting both communication data and audio data.

11.16 GPIO interfaces, with customizable input/output directions.

12.2 RS485 interfaces, which can be used in series (RS485 IN for input, and RS485 OUT connected to another RS485 IN for simultaneous control).

13.One RS232 interface supporting bidirectional data transmission and reception.

14.Each input features adjustable sensitivity (0dB/15dB/20dB/24dB) and independent 48V phantom power control.

15.The volume of input and output audio signals can be independently adjusted, with a range of mute, -60.0 to +12dB.

16.Input/output channels provide optional DSP functions such as signal generator, noise gate, feedback suppression, equalization, high-pass, low-pass, delay, expander, compressor, limiter, ducking, FIR, etc.
