●REV. TIME (Reverberation Time)

How it Affects the Sound:

The natural reverberation time of a room depends primarily on its size and the characteristics of its inner surfaces. This parameter, therefore, changes the apparent size of the acoustic environment over an extremely wide range.

What it Does:

Adjusts the amount of time it takes for the level of the dense, subsequent reverberation sound to decay by 60 dB (@ 1 kHz).

Control Range:

1.0 – 5.0 seconds.

The reverb time in a small-to-medium size hall would be between 1 and 2, and in a large hall it is normally between 2 and 3.

●EFCT TRIM (Effect Trim)

Performs fine adjustment of the level of all the effect sounds.

Control Range:

–3 dB to 3 dB

●DELAY

Adjusts the delay between the direct sounds (at the main left, center and main right channels) and the effect sounds (at the front effect and rear effect channels). The larger the value, the later the effect sounds are generated.

Control Range:

15 – 30 milliseconds
