Working with the Channel Racks
Making Filter, Gain, and Phase Settings
The Pre rack for MIDI channels allows you to open the Input Transformer . For further
information, see
“The Input Transformer” on page 595.
The Pre rack for audio-related channels features a high-cut and a low-cut filter as well
as gain and phase settings. These are described in the following sections.
Using the High-Cut and Low-Cut Filters
Each audio-related channel has separate high-cut and low-cut filters that allow you to
attenuate signals with frequencies that are higher or lower than the cutoff frequency.
To set up the high-cut filter for a specific channel, proceed as follows:
1. Activate the “Show Channel Racks” button on the toolbar, click Racks, and
activate “Pre (Filters/Gain/Phase)”.
2. Activate the On/Off button to activate the high-cut filter.
3. Drag the slider to the left or to the right to adjust the cutoff frequency.
The available range spans from 20 kHz to 50 Hz.
To set up the low-cut filter for a specific channel, proceed as follows:
1. Activate the On/Off button to activate the low-cut filter.
2. Drag the slider to the left or to the right to adjust the cutoff frequency.
The available range spans from 20 Hz to 20 kHz.
Ö Both filters have a slope of 24 dB per octave.
Changing the Input Gain
Each audio-related channel and input/output channel features a Gain slider for the
incoming signal. This way, you can change the level of a signal before the EQ and the
effects section. This is useful as the level going into certain effects can change the
way the signal is affected. A compressor, for example, can be “driven” harder by
raising the input gain. Gain can also be used to boost the level of poorly recorded
signals.
• To cut or boost the gain, drag the gain slider to the left or to the right, or double-
click to enter a new value in the value field.
