ART HQ231 ecualizador gráfico 31 bandas, 2 canales
General
Give your monitor mix, side-fill monitors and PA speaker a boost with the HQ231 2x 31-band graphic equalizer by ART. Equipped with a Feedback Detection Circuit, this EQ allows you to accurately control the frequencies. With active balanced and unbalanced inputs and outputs, RFI filters and LED level indicators, the HQ231 is packed with features that make it ready for professional use.
Feedback Detection Circuit
The Feedback Detection Circuit system has been developed in-house by ART and switches on an LED indicator as soon as the equalizer receives the best available signal. This tells you which frequency band best matches the feedback frequency so the sound technician can reduce that band's gain and effectively eliminate any feedback, without negatively affecting audio quality. Now, that's a solid piece of technology by ART.
Professional Components
The 45 mm sliders can be set with a boost or cut range of 6 dB to 12 dB and the HQ231 is outfitted with a passive bypass switch, a ground lift switch and a constant Q-filter. The latter ensures the Feedback Detection Circuit works more efficiently and at a faster rate. Hook up the EQ to external devices using the balanced XLR, TRS jack or unbalanced RCA inputs found on the back.

de faders en draaiknoppen zijn stevig lopen soepel
de high pass en low pass filter zijn echt een mooie toevoeging
je kan snel een ruimte in stellen met deze knopen
de schuiven worden bijna niet meer gebruikt
de behuizing is steving en bij is best zwaar
veel aansluitmogelijkheden is altijd fijn
ben zeer tevreden
