SPL PQ Mastering Equalizer

The Ultimate Mastering EQ. The SPL PQ is a fully parametric, dual-channel five-band equalizer in a 19" rackmount box, available in red or black.

The SPL PQ Mastering Equalizer is a fully parametric, dual-channel five-band equalizer that features 120V Rail Technology and the precise sound that SPL is famous for.

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.

The PQ Mastering Equalizer was designed, developed and manufactured in Germany.
