Microphone Mixing
The QM input can carry up to two microphone channels from a remote QM
transmitter. The microphone signals are fed into a microphone mixer while four
bands of equalization are applied to each microphone signal. The output is then
routed to the three audio mixers, left, right and speech.
Program Mixing
The microphone mix described previously, and the program left and right audio
inputs are fed to a mixing stage. The mixer combines the program audio and the
microphone signals into three outputs, program (stereo left and right) and speech
(monaural). The microphone signals can be mixed into the stereo program and
the stereo program can be mixed into the speech. After mixing, volume,
equalization and tone control can be applied.
NOTE: The QM-AE is compatible with 2-Series control systems only.
NOTE: For more information on this and other QM applications, refer to the
latest revision of the Crestron MediaManager Control, Switching and
