Functions and Operation
Constant Q and proportional Q modes
Each frequency band consists essentially of two fully parametric equalizers: one for constant Q mode and one for proportional (or variable) Q mode, selectable per band. The PQ is the first equalizer to offer both modes, endowing it with double equaliza- tion power for demanding corrective and creative applications.
In constant Q mode, the selected bandwidth remains unaffected by the amplitude setting, making it the best choice for corrective applications (e.g. to eliminate unwanted frequencies). In proportional Q mode, the amplitude is reduced as the bandwidth is raised and vice versa. With the smallest bandwidth setting, the maximum amplitude reaches +/- 11.5 dB, while it is reduced to +/- 2.5 dB with the broadest bandwidth setting. The Proportional Q mode is better suited for creative,
Con. Q Keys
These keys switch in the constant Q mode (illumination on) for each filter band. In proportional Q mode, illumination is off.
PLEASE NOTE: It is impossible to activate the ON and Con. Q keys simultaneously, please always press one key after another.
Link mode
All switching functions can be linked to operate both channels from one master channel. This is particularly recommendable for stereo operation. Both channels can be specified as master channel. Pressing the central key with the arrow in left direction activates link mode with the left channel as master, pressing the key with the arrow in the right direction activates link mode with the right channel as master.If the link mode is activated, you can bypass the complete PQ electronics by deactivating the ON key of the master channel (signals are routed from inputs to outputs), because the ON key of the master channel also activates the ON key of the linked channel. Deactivating the ON key of the linked channel only bypasses this channel, while the master channel remains active.
