No Data Manipulation
The Model 85 performs minimal process-
ing to the AES/EBU digital audio data. The
signal is received, converted to a standard
logic signal, then retransmitted using
rugged driver circuits. No timing “correc-
tion” is performed. No data is manipulated,
added, or changed. The Model 85 as-
sumes that your digital signals have been
carefully created and simply need to be
distributed to multiple inputs. In an age
when everyone wants to “fix” your digital
signals the Model 85 takes a “hands off”
approach. With a nominal 60 nanosecond
input to output delay, the outputs are
essentially identical to the inputs.
Installation
In this section you will be installing the
Model 85 in an equipment rack. AES/EBU
input and output connections will be made
using the ten XLR-type connectors located
on the back panel. AC mains power will be
connected to the Model 85.
System Components
The shipping carton contains a Model 85,
User Guide, and warranty card. Units
destined for North America are shipped
with an AC mains cord. Your dealer or
distributor will provide an AC mains cord
for non-North American destinations.
