The HVQ231/HVQ131 offers 31 band graphic equalization with 1/3 octave filters and superior constant ¡°Q¡± devices.
Offering the ability to increase signal-to-noise ratio by up to 20dB,the STK HVQ EQs make improvement in noise specs of almost any sound systems.
The HVQ131 is a 1/3 octave single 31 band graphic equalizer in a 2 rack package. The HVQ231 is a 1/3 octave dual 31 band graphic equalizer in a 3 rack package,The long throw, high resolution faders allow precise adjustment of each constant Q band.
The HVQ131/HVQ231 has built-in noise reduction and an on board limiter. Logical LED meters are present for level and gain reduction.
