SIGNAL TYPE
AND NAME
DESCRIPTION
Analog input
<Boost>
Applies boost at the QM input. This value can be applied directly or saved into
a skew preset.
Boost compensates for overall signal loss that can occur over cable lengths up
to 300 feet.
Valid boost values range from 0% to 100%.
Analog output
<Boost_F>
Reports the boost being applied at the QM input.
Analog output
<SkewPreset#_Recalled>
Reports the skew preset currently being recalled.
Slot 7: C2I-RX-MIXER
The C2I-RX-Mixer module is built into slot 07 of the QM-RMCRX-BA
QuickMedia control system and audio/video receiver. It provides one QM input
labeled QM that receives four channels of digital audio as follows:
•
Two channels of stereo program audio, referred to as LEFT and
RIGHT.
•
Two microphone channels referred to as MIC 1 and MIC 2.
The unit provides one 9-pin balanced/unbalanced line level audio output labeled
AUDIO, with three channels labeled L, R and SPCH.
The Mixer module can mix the four input channels into any output channel. In
addition, an onboard four-band equalizer (160 Hz, 500 Hz, 1.2 kHz, and 3 kHz)
for MIC 1 and MIC 2 applies equalization to the mic audio before mixing.
The Mixer module provides up to five mixer presets, where a mixer preset
consists of 12 mixing levels (four mixing levels each for AUDIO L, R, and
SPCH).
In addition, the Mixer module supports up to 10 microphone EQ presets for
MIC 1 and MIC 2, where a microphone EQ preset consists of eight trim values
(four trims each for MIC 1 and MIC 2).
When audio automatic compensation is enabled (auto compensation models
only), the microphone EQ presets are not used. Instead, the eight microphone
EQ values stored at the QM transmitter for the selected audio source are
propagated to the QM receiver.
For the QM-RMCRX-BA, auto compensation is enabled via the
<EnableAudioAutoComp>
input on the C2I-RX-GENAUDIO-AUTOCOMP
slot.
