The 3-DRX operates from 90 to 264 VAC at 47 Hz to 63 Hz input making the unit quite
versatile. Connectors on the rear panel conform to AES-3 XLR type connectors and
AES-3ID type BNC connectors. The 3-DRX can be selected to be bridging input, 110
Ohm or 75 Ohm terminating inputs. If power is lost to the unit a bypass relay will bring up
the Digital source 1 input directly to the AES outputs bypassing the unit. The indication
on the remote relay output will be that of Source 1 and the Auto/Manual indicator output
will be “Manual”.

NOTE

Automatic detection of a serial link on the remote connector will override

any manual rear panel remote control inputs to the unit. (See installation for
details).
