Functions and Operation
Amplitude
Amplitude settings are freely adjustable from -/+ 15 dB in proporional mode and from
-/+ 20 dB in constant Q mode.
Frequency
Each channel provides fi ve fully parametric frequency bands covering 10 Hz to 28
kHz. Each band overlaps its neighbor by one octave and can be independently acti-
vated and deactivated.
The following frequency bands are provided:
LF (Low Frequencies): 10 Hz - 235 Hz
LMF (Low Mid Frequencies): 35 Hz - 720 Hz
MF (Mid Frequencies): 330 Hz - 7.1 kHz
HMF (High Mid Frequencies): 670 Hz - 16 kHz
HF (High Frequencies): 1.2 kHz - 28 kHz
Bandwidth
Bandwidth is adjustable between 0.1 and 3.7 Q in proportional Q mode and between
0.7 and 15 Q in constant Q mode. The extremely high maximum bandwidth in constant
Q mode enables tight, selective control in precision applications.
Illuminated keys
The PQ features illuminated keys that illuminate brightly when activated. The fi nal
software version will provide dimly lit keys (25% brightness) when deactivated for
ease and security of operation. The current software version (240H) switches illumi-
nation off when keys are deactivated.
LF, LMF, MF, HMF and HF keys
These keys activate (key lamps lit) or deactivate (lamps off) the 10 fi lter bands.
