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.
