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.

Post Gain

Ampliﬁes the signal after it has been compressed to bring up the volume. Range 0dB to 36dB
