@@@
PRE-DELAY (OFF, 1ms to 100ms)
Adjusts delay time between the direct sound and the onset of
reverberation. Higher settings make the simulated space sound
larger. Because some pre-delay is inherent in all program material,
it is recommended to begin with the parameter set to OFF, then
make adjustments accordingly.
@@@
ROLLOFF (500Hz to 20.0kHz, OFF)
Adjusts the absorption of high frequencies in the simulated space.
It is recommended to begin with a low setting to simulate large
spaces.
@@@
SIZE (4m to 30m)
Adjusts the length, width, and height of the simulated space.
@@@
SPEECH DETECT (ON, OFF)
Controls a circuit that distinguishes monaural speech from other
input sources. When set to ON, effects are lowered to minimize
interference with monaural speech. When stereo input sources are
present, the front left and right channels are independently used as
inputs for ambience synthesis. When strong monaural speech is
present in the input source, the monaural component of the
ambience effect is reduced and the stereo component of the effect
is increased. When set to OFF, the amount of ambience synthesis is
dynamically controlled.
@@@
SURR ROLLOFF (500Hz to 20kHz)
Applies a high-frequency rolloff to the MAIN AUDIO OUTPUTS
labeled SIDE L/R and REAR L/R. This rolloff is only applied to output
signals generated by the MC-12. Signals above the rolloff that are
part of the source recording are passed through without filtering.

@@@FRONT STEERING (OFF, MSURR, MUSIC, FILM)
Adjusts front steering to match the input source. When set to FILM,
maximum front steering is applied. When set to MUSIC, moderate
front steering is applied. When set to MSURR, minimum front
steering is applied. When set to OFF, no front steering is applied. It
is recommended to set this parameter to FILM for film sources and
to MUSIC, MSURR, or OFF for music sources.
@@@
LIVENESS (30ms to 20.2s)
Depends on the SIZE parameter setting. The LIVENESS parameter
adjusts the amount of effect re-circulation. Higher settings mimic
more reflective simulated space surfaces and increase decay time.
@@@
MID RT (24ms to 24.3s)
Full name: Mid-range Reverberation Time
Depends on the SIZE parameter setting. The MID RT parameter
adjusts the amount of time required for mid-range sounds to decay
60dB.
Setting the BASS RT or MID RT parameters to a high value
might produce undesirable or damaging audio.
CAUTION
@@@MIX ROOM (SMALL, LARGE)
Indicates the size of the mixing room that was used. When the
parameter value is LARGE, it is recommended to set the
RE-EQUALIZATION parameter for the selected listening mode to
ON (if applicable).
