ADMS 44.22 Installation and Operation Manual
DESCRIPTION
Functional Description
1.1 Introduction
The ADMS 44.22 is an 8x2 stereo matrix switcher with four stereo analog
and four stereo AES inputs, and two independent stereo analog and AES outputs in
a 1-RU profile. Each input channel is equipped with an automatic level control cir-
cuit and a fully configurable 3-band equalizer. The ADMS 44.22 provides both
word clock in and word clock out signals for synchronization to external digital
equipment. Additionally, the four stereo AES inputs support high-quality real-time
sample rate conversion for connection with asynchronous digital sources. Each out-
put channel is equipped with an automatic level control circuit and parallel stereo
analog and stereo AES outputs. Either output can be monitored locally from head-
phones or the monitor outputs, or the stereo PPM meter.
Any or all of the inputs may be mixed, faded, dimmed to either or both out-
put channels. Fade rates, dim levels, and mix modality are all fully programmable.
The ADMS 44.22 is equipped with a digital expansion port that allows two units to
operate together as a 16x2 stereo matrix switcher. The ADMS 44.22 can be con-
trolled through RS-232 serial command from a standard ANSI terminal or dedicat-
ed serial control device, as well as from front panel switches and remote control
inputs on the rear. The ADMS 44.22 has four programmable relays and nine pro-
grammable open collector outputs for controlling external device, and can transmit
unit status and GPI information to the controlling device for incorporation into
broadcast automation systems. All unit settings can be saved into user memory, or
be automatically saved whenever a setting is changed.
