SPL PQ

The PQ Mastering Equalizer – Model 1540/1544 is a new revised edition of the well-known SPL PQ Mastering Equalizer – Model 20Both units are based on our 120V Rail Technology.

The new PQ features the same high-quality characteristics as the previous mode. 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 equalize.

The SPL PQ Mastering Equalizer is a fully parametric, dual-channel five-band equalizer, based on SPL’s pioneering 120V technology. Able to switch between constant and proportional Q modes with the push of a button. The circuit is unique and has not yet been achieved in any other analog equalizer.

All five bands of the SPL PQ can each be activated or deactivated. Then 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 equalize.

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

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

With the Gain-Switch, you can reduce a maximum increase or attenuation of the amplitude by the factor 3/4. This 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.
