SPL PQ Model 1544 (Red)
SPL PQ Mastering Equalizer - Red
PQ is a fully parametric, dual-channel five-band equalizer. The PQ Mastering Equalizer – Model 1540/1544 is a new 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 seperately switch between Constant Q and Proportional Q. This kind of circuit has not yet been achieved in any other equalizer.
Several details of this revision were adjusted to current requirements.
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 realize. You can adjust parameters Gain, Frequency and Q in 41 steps with detent potentiometers.
120V Rail Technology is our reference technology developed and manufactured to run on an operating voltage of 120 volts, which corresponds to twice that of discrete operational amplifiers and four-times that of semiconductor operational amplifiers.
120V Rail Technology reaches outstanding technical and sonic performances. Technically especially in terms of dynamic range and headroom and sonically especially in reproducing the finest details and delivering a totally relaxed sounding audio experience. Music sounds absolutely natural and hearing fatigue is drastically reduced.
Even the best audio measuring equipment arrives at the boundaries. In same situations we ended up just measuring the Audio Precision Cascade 2 measuring device and we cannot say how good the 120V Rail Technology actually performs.
The PQ is part of a whole new 120V Mastering Universe which will include, Iron Compressor, DMC Mastering Console, PASSEQ Passive EQ, Phonitor Headphone Amp, Phonos Phono Preamp, MC16 Monitor Controller, M/S Link & Refiner, HVR DAC, and the Hermes Mastering Router.
