Chapter 13: Impact 87
Impact Make-up Control
Make-Up adjusts the overall output gain. Be-
cause large amounts of compression can restrict
dynamic range, the Make-Up control is useful
for compensating for heavily compressed sig-
nals and making up the resulting difference in
level. When Impact is used on stereo or multi-
channel tracks, the Make-Up control determines
master output levels for all channels. The range
of this control is from 0 dB of attenuation to
+40 dB of gain.
Impact Ext Control (Side-Chain)
External On/Off enables and disables side-chain
processing. With side-chain processing you can
trigger compression from a separate reference
track or external audio source. The source used
for triggering side-chain processing is referred
to as the Key Input.
Impact Listen On/Off Control
Key Listen On/Off enables and disables audi-
tioning of the Key Input (the reference track or
external audio source used for triggering side-
chain processing). This is useful for fine-tuning
Impact’s compression settings to the Key Input.
Make-Up
Applying large amounts of Make-Up gain
will boost the level of any noise or hiss pres-
ent in audio material, making it more audi-
ble.
See “Using the Impact Compressor” on
page 88 for instructions on setting up and
using a key input.
