The analog monitor output operates in stereo and has a low impedance. It can be used as line and headphone output and supports 192 kHz at 112 dBA SNR. The routing matrix can assign any of the 36 stereo input pairs to the monitor output.

AUTO DELAY COMPENSATION

A typical application example is the use of a HDSP MADI PCI-card in a computer with the ADI-642 as external AES interface. As MADI transmits 64 channels, up to eight ADI-642 can be used to provide all 64 channels via 32 AES I/Os. The integrated Matrix Router makes such a setup easy to be configured. The MADI signal is passed through from device to device. When passing through the MADI signal, a delay of a few samples per ADI-642 occurs, causing the AES inputs and outputs to show an offset. This problem is fixed by the Automatic Delay Compensation. Each ADI-642 automatically detects which unit it is within the chain, and corrects the AES input and output data so that all AES I/Os operate sample-aligned. The additional Auto Configuration mode sets up all ADI-642 to use consecutive AES I/Os. A manual configuration via each unit's Matrix is not required.

The ADI-642 is compatible to MADI interfaces of companies like Sony, Merging, Lawo, Euphonix, Stagetec, Jünger, Audio Service, AMS and others.
