2.High-performance AD/DA, low distortion, wide dynamic range, and pure sound quality.
3.Online connectivity, efficient and concise, engineering-friendly operation interface software, real-time control of all functions and monitoring of machine working status.
4.4-channel MIC/LINE input, 4-channel balanced output.
5.28-channel AES67 network input, 28-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.Support power LINK interface for hand-in-hand power supply during multi-machine expansion, facilitating engineering installation.
The panel features 14 LEDs indicating audio and system status, along with a phantom power switch button, enabling user-friendly human-machine interaction. Support the expansion from 2 machines to 1 1U machine cabinet installation, with panel design featuring bracket mounting holes. Support automatic audio mixing function
