Audio Mixer Signals (continued)

SIGNAL TYPE

AND NAME

DESCRIPTION

Analog inputs

through

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.

Analog outputs

<Mic2EQTrim1_F>

through

<Mic2EQTrim4_F>

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.
