Digital Audio Processor
AMP-44T is a 1U-wide network audio processor that adopts the AES67 network audio transmission protocol, supports Dante multicast compatibility, and supports 4 analog + 4 network audio input and output. It supports rich DSP functions such as automatic mixing and echo cancellation, and supports GPIO control, making it suitable for network node audio transmission processing.
Functional features:
1.Sampling rate is 48kHz.
2.High-performance AD/DA, low distortion, wide dynamic range, and pure sound quality.
3.Online, efficient, and user-friendly operation interface software for engineering, providing real-time control of all functions and monitoring of machine operating status.
4.4-channel MIC/LINE input, 4-channel balanced output.
5.4-channel AES67 network input, 4-channel AES67 network output.
6.Each input features adjustable hardware gain (0dB/15dB/20dB/24dB) and independent 48V phantom power control.
7.The volume of input and output audio signals can be independently adjusted, with a range of mute, -60.0 to +12.0 dB.
8.2 Gigabit Ethernet ports, capable of being connected in series for networking. The NETA port supports POE power supply.
9.Supports a power LINK interface for hand-in-hand power supply during multi-machine expansion, facilitating engineering installation.
10.The panel features 14 LEDs indicating audio and system status.
11.Support automatic audio mixing function.
12.Supports 8 GPIO interfaces.
13.Supports 1-channel echo cancellation, background noise reduction, and automatic gain control functions.
