8-in 4-out Digital Audio Automatic Switcher

Name: AES Audio Auto Switcher  Model: ZH-AES0804T

Brand: Zongheng Tiancheng                   Channels: 8 In 4 Out

Note: 1. Loop Auto-Switching: Automatically detects input source threshold signal loss and switches to the next channel in a loop detection manner. 

2. Primary/Backup/Auxiliary Auto-Switching: Input channel 1 is primary, channel 2 is backup, and channel 3 is auxiliary. Default output distribution is 4 channels. When the primary signal is lost, it automatically switches to the backup input; if the backup is lost, it switches to the auxiliary input. When the primary signal is detected as normal, it automatically switches back to the primary input.

3. Front Panel Pre-Listening Function: Built-in digital-to-analog conversion allows pre-listening to any input signal via headphones.

I. Overview

The AS series matrix switcher is a switching device for AUDIO signals, capable of routing multiple AUDIO input signals to any one or multiple output channels simultaneously. It utilizes high-bandwidth chips for high-fidelity signal output,

stable performance, and supports cascading multiple units to expand channel capacity. It features manual panel control, power-off scene protection, and switching memory retention.

Equipped with an RS-232 communication interface for computer connectivity, along with communication protocols and demonstration software.
