AND NAME
DESCRIPTION
Analog inputs
<
Mic2EQTrim1

through
<
Mic2EQTrim4
>
These signals have NO effect if automatic audio compensation is enabled.
Sets the four MIC 2 EQ trims (at 160Hz, 500Hz, 1.2kHz, and 3kHz).
Valid analog values range from -120d (-12dB) to +120d (+12dB), adjustable in
increments of 0.1dB (1d = 0.1dB).
A trim of 0d (0dB) means that the signal will pass unaffected.
Out of range values will clip the trim to the minimum or maximum value.

Indicates the trim being applied to each band of the MIC 2 equalizer.
Slot 8: C2I-RX-GENAUDIO-AUTOCOMP
The General Audio Controls module is built into slot 08 (with auto
compensation). Refer to Appendix B on page 65 for additional auto
compensation information.
The QM-RMCRX-BA provides one QM input labeled QM that receives four
channels of digital audio as follows:
•
The two channels of stereo program audio are referred to as LEFT and
RIGHT.
•
The two microphone channels are referred to as MIC 1 and MIC 2.
The unit provides the following audio outputs:
•
One line-level output labeled AUDIO with three channels labeled L, R
and SPCH. Each channel provides muting, volume and tone controls.
•
One powered amplifier output labeled SPEAKER with two channels
labeled L and R. The SPEAKER output duplicates the AUDIO L and R
outputs and allows speakers to be connected directly to the
QM-RMCRX-BA.
The QM-RMCRX-BA supports up to 192 source gain compensation presets,
which allow for normalization of audio levels between different sources.
When auto-compensation is enabled (by setting the
<EnableAudioAutoComp>
input high), the audio compensation presets are not used. Instead, the audio
compensation value stored at the QM transmitter for the selected audio source is
propagated to the QM-RMCRX-BA.
NOTE:
Mic tone settings apply equally to both microphones.
