Manufacturer's Description from SPL

• The PQ Mastering Equalizer is a fully parametric, dual-channel five-band equalizer.

• The PQ Mastering Equalizer – Model 1540/1544 is a newly revised edition of the well-known SPL PQ Mastering Equalizer – Model 2050.

• Both units are based on our 120V Rail Technology. The new PQ features the same high-quality characteristics as the previous model.

• All five bands can each be activated or deactivated and you got the possibility (for every single band) to separately switch between Constant Q and Proportional Q. This kind of circuit has not yet been achieved in any other equalizer.

• Each channel can completely be activated or deactivated, thanks to Auto-Bypass, even automated in a freely selectable time frame.

• Bypass of each band and constant Q of the left side can be controlled by the right side in Link mode.

• Thanks to the 1/4 Gain-Switch, you can reduce a maximum increase or attenuation of the amplitude by the factor 3/4, which regulates the potentiometer from max +/-20 dB to +/-5 dB cut. This gives you the possibility to perform small corrections, as common in Mastering or higher amplitudes in Proportional-Q mode.

• Thanks to the detented potentiometers, a precise recall is very easy to realize. You can also adjust parameters Gain, Frequency, and Q in 41 steps with the detented potentiometers.
