ADMS 44.22 Installation and Operation Manual
INSTALLATION

Powered Monitor Output
The ADMS 44.22 provides a balanced line-level stereo output for monitor-
ing Output 1 or Output 2 using powered monitor speakers.
The protocol for connecting the Powered Monitor outputs to balanced and
unbalanced equipment is identical to that described for the analog outputs in the pre-
vious section.

AES Digital Inputs & Outputs
The ADMS 44.22 provides four stereo AES inputs and two stereo AES out-
puts via 3-position removable Euroblock connectors on the rear panel, as shown in
the picture below.
AES Outputs 1 and 2 parallel Analog Outputs 1 and 2. When the Sample
Rate is running at 88.2 or 96 kHz the AES inputs and outputs both run in AES sin-
gle-wire (double speed) mode. In single wire mode both the left and right channels
are transmitted at 2x the base AES frame rate (44.1 / 48 kHz). The ADMS 44.22
does not support double-wire mode, which transmits two consecutive samples of the
same channel at the base AES frame rate and requires two AES connections to con-
vey a stereo signal.
The AES inputs and outputs are transformer-balanced and have an 110
Ω
impedance. The inputs are ac-coupled, while the outputs are dc-coupled. Use only
110
Ω
AES digital cables to connect the ADMS 44.22 to and from your external AES
