Topic: ADAT voor live sound?? (5-4-2011 09:34:00)
Hi,
I'm the developer of the Appsys ADAT Multicore extenders and want to give some useful hints here:
The suggested "bare metal" RS-485 does not work with several devices (notably Yamaha equipment @ 48kHz, Presonus Digimax FS preamp, all devices using JetPLL circuits etc.). because the timing accuracy of the ADAT signal degrades during the transmission (the signal jitter increases significantly), causing dropouts and crackles. The ADX-32B and ADX-64B-PRO devices are also RS-485 based, but they also incorporate a special reclocking circuitry which ensures that all clock edges are properly aligned and work with *every* ADAT device on the market.
Greets,
Rolf
