Concert Hall Parameters
The Concert Hall Effect generates the appropriate early reflections for stereo simulation of many different halls, and sends the reflections to all channels in addition to the direct signal in the main speaker. This Effect is not appropriate for highly percussive music.

LIVENESS adjusts the amount of recirculation within the effect. Higher values mimic more reflective surfaces in the simulated space and increase the amount of time it takes the sound to decay. At very high values, the decay is audibly less smooth than in the Church and Cathedral Effects, which are more effective at simulating very live spaces.
ROLLOFF mimics the absorption of the air in the hall and, typically, should begin with a low frequency to simulate large 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. If there is a strong monaural speaking voice present at the same time, this component of the input to the Concert Hall effect is reduced while the stereo component is increased.
If the input signal is pure monaural speech the reverb is almost entirely attenuated. SPEECH DETECT is a real benefit to some popular music (where spoken voice, such as rap, occurs along with the music), stereo television and early stereo movies. Any stereo material which was not carefully mixed for surround is a good candidate for playing through the Concert Hall effect with Speech Detect on.
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 side and rear speakers. When there are no side speakers, it adjusts the amount of ambient signal mixed into the main loudspeakers.
