MC-12

SETUP

AUTO ON, OFF

SETUP INPUTS DVD1 ANLG IN LVL AUTO

Activates automatic adjustment of 2-channel analog audio input levels. When ON is selected, the MC-12 automatically monitors and optimizes 2-channel analog audio input levels. When the input signal is too high, the MC-12 quickly decreases input levels to avoid overload. When the input signal is too low, the MC-12 slowly increases input levels to maximize signal-to-noise ratio and dynamic range.

When OFF is selected, the MC-12 does not automatically monitor and optimize 2-channel analog audio input levels. The MANUAL parameter is available for manual input level adjustment.

MANUAL -18 to +12dB

SETUP INPUTS DVD1 ANLG IN LVL MANUAL

Allows manual adjustment of 2-channel analog audio input levels. When the MANUAL parameter setting is adjusted, the MC-12 automatically sets the AUTO parameter to OFF, deactivating automatic input level adjustment. When the AUTO parameter is set to ON, manual input level adjustments are retained (though not applied).

Note:

When the AUTO parameter is set to ON, the MC-12 will not make automatic input level adjustments that exceed the MANUAL parameter setting.

AUTO GAIN

SETUP INPUTS DVD1 ANLG IN LVL AUTO GAIN

Indicates the current amount of input level adjustment for the assigned stereo analog audio input connector. When the AUTO parameter is set to ON, the AUTO GAIN parameter indicates the amount of adjustment being applied until automatic adjustments are made. Then, the AUTO GAIN parameter indicates the amount of automatic input level adjustment being applied.

When the AUTO parameter is set to OFF, the AUTO GAIN parameter indicates the amount of manual adjustment being applied. (In other words, the AUTO GAIN parameter reflects the MANUAL parameter setting.)

LEVEL METERS

Indicate fluctuating input levels in the front left (L) and front right

(R)channels for the selected input. Like status menu level meters, ANLG IN LVL menu level meters indicate input levels for both digital and analog audio sources. However, ANLG IN LVL menu input level adjustment only affects 2-channel analog audio sources.

When the on-screen display is configured for a blue-screen background, level meters appear in combinations of green, yellow, and red. Green indicates low input levels, yellow indicates normal input levels, and red indicates high input levels and the onset of overload. When the on-screen display is not configured for a blue- screen background, level meters appear in white.
