Core Effects Descriptions

Leveling Amp

The first compressors developed in the 1950's were based on a slow-acting optical gain
cells which were able to control the signal level in a very subtle and musical way. This
effect is a digital recreation of the leveling amps of yesteryear.
The leveling amp uses a large amount of "lookahead delay" to apply gentle gain
reduction. Because of this delay, the leveling amp is not suitable for applications which
require realtime monitoring of the signal. This smooth and gentle compressor is
designed to be used in situations where delay does not pose a problem, such as
mastering a mix or compressing prerecorded stereo material.
Post Gain is the only control on the leveling amp. This control is used to make up the
volume lost by the compression. The Compression Ratio is fixed at about 2.5:1. If a
large peak is detected, the effect will automatically increase the compression ratio to
keep the audio output controlled.
The gain reduction meter shows you how much gain reduction is being applied. Since
the gain reduction meter displays how much the gain is being turned down, the meter
moves from right to left, instead of left to right like most meters.

Mono Delay 100

The Mono Delay 100 is a monophonic delay line with a maximum delay of 100 milli-
seconds. It's useful for slapback, doubling and stutter effects when you don't want or
need a stereo delay. Stereo signals are summed together before entering the Mono
Delay. Very short delay times combined with a high feedback amount can be also used
to create monotone robotic-sounding effects.
