CENTER LEVEL adjusts the output level from the center speaker.

SUBWOOFER LVL boosts or cuts the subwoofer output level. Although the normal subwoofer level is set during the calibration procedure, with some recordings it may be desirable to increase or decrease this deep bass level.

EFFECT LEVEL adjusts the loudness of the Effect.

Cathedral

The Cathedral Effect uses a reverberation algorithm which emphasizes

 

rich, smooth reverberant decay in large spaces. As its name indicates, it

 

works well for simulating a space with a long reverberation time relative to

 

its size, such as a cathedral.

MID RT (midrange reverberation time) is the time required for midrange sounds to decay 60dB in level.

BASS RT (low frequency reverberation time) depends on MID RT and is expressed as a multiplier. BASS RT should be set to 1.0 x MID RT for a more natural effect in smaller spaces.

HALL SIZE allows you to select hall sizes of lengths ranging from 20-38 meters (in increments of 2 meters).

PRE-DELAYincreases the delay between the direct sound and the onset of reverberation. Because some pre-delay is inherent in the program material, a value of 0 is usually a good starting point. Increasing the pre-delay value will make the hall sound larger.

ROLLOFF mimics the absorption of the air in the hall and, typically, should begin with a low frequency when simulating larger spaces.

SPEECH DETECT activates a circuit that distinguishes monaural speech from other inputs. Essentially, this control turns down the effect to make speech clearer. Whenever stereo signals are present, the right and left input channels are used independently as inputs to the ambience synthesis.
