Crestron
QM-MD7x2
QuickMedia™ Matrix Switcher/Mixer
In addition to the local AV inputs, the unit provides two QM inputs labeled IN 6 and
IN 7 that each receive video, stereo program audio and two channels of microphone
audio (MIC 1 and MIC 2) from QM transmitters via CAT5.
At each QM input is a QM audio receiver circuit that supports up to 100 "QM Link"
presets for peaking and boost. The peaking and boost settings improve the
transmission of the encoded audio signal over long cable lengths.
The two QM outputs are labeled OUT 1 and OUT 2. The unit also provides two line-
level audio outputs labeled AUDIO OUT 1 and AUDIO OUT 2. Each line-level
output consists of three channels labeled PRG L, PRG R and SP.
•
Any of the seven video sources can be switched into either QM output.
•
Any of the seven program audio sources can be switched into the stereo
program channel of QM OUT 1 or 2. The audio source that is switched to
QM OUT 1 will also be routed to the mixing section of AUDIO OUT 1.
The audio source that is switched to QM OUT 2 will also be routed to the
mixing section of AUDIO OUT 2.
•
Either of the two remote microphone pairs from QM IN 6 and QM IN 7 can
be mixed with the two local microphones and routed to the MIC 1 channel
of QM OUT 1 or 2. There are no microphone signals on the MIC 2 channels
of the QM outputs. The mic mix that is routed to QM OUT 1 will also be
routed to the mixing section of AUDIO OUT 1. The mic mix that is routed
to QM OUT 2 will also be routed to the mixing section of AUDIO OUT 2.
The Input Switching symbol provides two methods for sending switching commands
to the MD7x2:
1. By programming the digital and analog signals, or
2. By programming serial strings.
The two methods should not be used simultaneously.
While using the SIMPL Windows programming manager, double-click on
