CL-12 LINEAR FADER CONTROLLER
Bypassing EQ
When necessary, it is possible to temporarily and quickly bypass the application
of EQ without altering the current non-zero gain value. The label BYPASSED is
shown on the EQ screen for any band that is bypassed.
To bypass EQ do any of the following:
X
Press the LF encoder.
X
Press the FREQ or GAIN encoder.
X
Press the HF encoder.
These controls act as toggles between bypass (gain = 0 dB) and the last
non-zero gain value, so pressing any encoder a second time will toggle off by -
pass and reapply the last non-zero gain value for LF, MID, or HF respectively.
When an EQ band is bypassed, its EQ LED goes out.
Setting the Q-Factor
The Q-factor controls the bandwidth that will be cut or boosted by the equalizer.
To set the Q-factor:
1. Press MENU.
2. Select CL-12 > EQ > Q-Factor.
3. Select one of the following options: 0.707, 1.0, 1.414, or 2.0.
The lower the setting, the wider the bandwidth, which means more
frequencies will be affected by EQ. The higher the setting, the narrower the
bandwidth, so the EQ adjustment wil be more selective.
For example, the following two images show a 10 dB LF peaking filter
applied to CH-1; however, the Q-factor for the left one is set to 0.707, while
the Q-factor for the right one is set to 2.0.
