In this video I review the SPL PQ, one of my favourite EQ’s. The PQ is a 5 band EQ with a lot of great features. A truly unique sound that rivals all high end EQ’s. The audio demos clearly show the verticality of this EQ and the different ways it can be used.
PQ is a fully parametric, dual-channel five-band equaliser. The PQ Mastering Equaliser – Model 1540/1544 is a new revised edition of the well-known SPL PQ Mastering Equaliser – 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 equaliser.
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.
Another highlight is the possibility to boost or cut the amplitude to 20 dB. If you only wish minor changes of the music material, you can reduce the intensity of the boost or cut by using the 1/4 Gain-Switch, which regulates the potentiometer from max +/-20dB to +/-5dB cut. This gives you the possibility to perform small corrections, as common in Mastering or higher amplitudes in Proportional-Q mode.
Thanks to detent potentiometers, a precise recall is very easy to realise. You can adjust parameters Gain, Frequency and Q in 41 steps with detent potentiometers.
