ART HQ231 Graphic Equalizer Two Channel 31 Band Constant Q Filtering Feedback Detection Circuit


ART HQ231 Graphic Equalizer Two Channel 31 Band Constant Q Filtering Feedback Detection Circuit


The HQ231 Dual 31-band Graphic EQ is perfect for any live sound application where there is a high feedback potential including monitor mixes, side-fill cabinets or high powered front-of-house mixes situations. The HQ231 features ARTs proprietary FDC Feedback Detection Circuit, with constant Q circuitry capable of delivering a 3 center frequency accuracy. Professional features like LED level metering, selectable 6dB or 12dB slider range, active balanced and unbalanced input output connectors, RFI filters, independent variable Hi Pass low cut and Low Pass high cut filters, variable input level control, passive bypass switch, clip level indicator, ground lift switch, and selectable line voltage switch make it ideal for any professional application or touring system. FDC Feedback Detection Circuit – FDC Feedback Detection Circuitry designed and developed by ART Engineering instantly illuminates an LED on the corresponding EQ band fader with the greatest sustained signal. The LED indicators can immediately show which band corresponds to the feedback frequency, allowing the sound engineer to reduce gain in that band to quickly kill the feedback while having a minimal impact on the sound of the live program material. The FDC also acts as a simple spectrum viewer while the concert proceeds showing where the hot areas are. During system setup and sound check, the FDC may be used to help identify room and sound system resonances. By increasing the gain until feedback, it is easy to identify those frequencies that are likely to be problems. Reducing the gain in these bands helps tune the sound system, and, remove problem areas before the show begins. It also helps increase the gain margin before feedback.

    I use the EQ in my bands PA system. It is very quiet and the feedback circuit makes ringing out the room very easy. Definitely worth the price.

    This was a little more expensive than similar 31 band stereo FLS Eqs , but having owned some other ART products I decided to try it.
    So far havent been disappointed, I am using it for two monitors and the FBS is a lifesaver to touch up after ringing out the system.
    Nice solid chassis, quite performance, and I/O options.

    Even though it isnt a long throw fader, there still is plenty of adjustment for most purposes.

    I received the unit today. Couldn’t wait to try it out as I wanted to see how it deals with feedback (what I’m paying over $100 more than other brands/models for). So I connected it to my un-powered mixer’s Output, set all sliders to middle position, connected my powered speakers to it, then turned everything on.

    Unit was on. So I picked up my microphone and cranked up the mixer output til I could hear feedback. Didn’t see any flashing/blink on the unit. All slider’s LED remained constant. The Bypass indicators were off, so I’m sure it’s not in bypass mode. But to make sure, I pressed the Bypass button and it sent a thunderous pop to my speakers. I turned way down the level on my speakers to be safe, and pressed the bypass button again, there was that loud pop noise again.

    I also notice the Line-level LEDs were not even on. So I adjusted the Level on the unit, turned it to max, no LED was even on. I turned off my speaker and cranked up the mic volume but the Line level LED didn’t even show a single light.

    So I popped in a CD, then crank up the outputs on the mixer. Still, none of the Line level LED was on. The slider’s LED still remained constant.

    So much for Feedback Detection Control. So much for 300 bucks. I’m packing this thing up and sending it back.
