Multiband Compression
There are 2 sections to the Multiband Compression control page: Main and Speed. The buttons on the left of the screen allow
you to navigate between pages.
MBC Main
♦ The Multiband Compressors switch enables or disables the multiband compression section. When disabled all of the
controls will be grayed-out.
♦ The Maximum Gain control works in conjunction with the Ratio control to determine how much gain is available below
threshold. If the Input AGC Ratio is set at Infinity:1 and the Input AGC Maximum Gain is set to 36dB, the Input AGC has
36dB of range below threshold. At a ratio of 2.0:1 and the same Maximum gain setting, the range is reduced by half to
18dB. The scale to the left of the Input AGC meter automatically adjusts as needed when changes are made to the Input
AGC Maximum Gain or the Input AGC Ratio to accurately reflect how much range is available below threshold.
♦ The Ratio control determines how much the output audio will be increased or decreased in relationship to the input
audio of the Input AGC section. For example, a ratio of 3:1 means for every 3dB of change in the level of the input audio,
the output will be changed by 1dB. Lower (looser) settings provide less control of the dynamics in this section but
provide a more open sound, while higher (tighter) settings provide more control at the expense of openness. The range
of this control is 1.0:1 to Infinity:1.
♦ Each band can be adjusted separately, or all bands may be adjusted simultaneously via the Coupled control.
