Filter Band Boost/Cut Control
Use this knob (labeled “dB” in the illustration) to adjust the gain of the filter band for the peaking, high and
low shelf filter types. This parameter is ignored for the other filter types. In the shelving filters the maximum
boost is +12 dB and the maximum cut is -24 dB. In the peaking filters the maximum boost/cut is ± 24 dB.
When you increase the boost for a filter band above 15 dB, the filter gets very aggressive and resonant. You
can use this feature to good effect when you need to reconstruct a resonance for a recorded instrument that
lacks one. For example, you could place a narrow +24 dB peaking filter between 60 and 80 Hz on a kick
drum track that lacked a “belly” for the drum.
Filter Band Frequency
Use this knob (labeled “Hz” in the illustration) to adjust the characteristic frequency of the filter. For the peaking
and bandpass filter types this controls the center frequency of the filter. For the high and low cut filter types this
control adjusts the 3 dB point of the filter. For the shelving filters this control adjusts the shelf transition point.
Filter Bandwidth
Use this knob (labeled “BW” in the illustration) to adjust the characteristic width of the filter. This control only
has effect for peaking, shelving and bandpass filter types. Please note that this parameter controls the bandwidth
(measured in octaves), not the quality factor (or “Q”). If you have been using Q controls, the numbers will
be backwards from what you are used to. Small numbers mean narrow filters and large numbers mean wide
filters. For peaking and bandpass filter types, this parameter controls the bandwidth of the filter in octaves. For
the high and low shelving filter types this parameter adjusts the amount of dip/peak and the slope of the shelf.
When this parameter is set to 0.1 you will get the largest dip/slope available and when the parameter is 2.5,
you will get a classic first order shelf (which has a transition band that is about 1 decade wide; e.g. if it is a
high shelf with a frequency of 10 kHz and a gain of 10 dB, the gain will be at 0 dB near 1kHz).
Controlling The EQ With The Transfer Function
As described in the operation guide earlier in this manual, you can control each band of the EQ directly from
the EQ transfer function display associated with the 6 band equalizer.
Master Gain
The one fader in ChannelStrip’s user interface controls the master gain of the plug-in. This fader is not shown
in the illustration of the EQ section, but it is shown in the overall processor illustration at the beginning of
this manual. The “Master Gain” fader allows you to add up to +10 dB of gain or up to -160 dB of attenuation
to the output signal from the EQ processor or compressor block (depending on the processor order) before
going to the limiter.
Delay Section
You can add up to 255 samples of delay to the output of ChannelStrip. This is useful for dynamically slipping
tracks, doing acoustical time alignment or compensating for the delay of other plug-ins in your mix.
You can use automation on the delay to create interesting dynamic flanging effects. Simply duplicate a track
and enable automation on the delay control for one of the copies. As you change the delay through one of the
copies you will create a nice, controllable phasey flanging sound.
