Product Description

This member of the HQ Series, HQ 231, features ART's FDC Feedback Detection Circuitry. The ART proprietary FDC differs from similar systems in that it is extremely fast. Although it illuminates the band with the greatest energy with the brightest LED, it doesn't fully discriminate between bands and will not get "stuck" on one band when there is no signal.

The HQ 231 utilizes a set of indicators that show which of the many EQ bands has the greatest energy. 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.

The unit also features constant Q circuitry, 45mm center detent sliders with selectable boost or cut range of 6dB or 12dB, balanced XLR, 1/4-inch and unbalanced RCA input and output connections, high and low pass filters, analog level metering, variable input controls, signal clip level indicators, ground lift switch, internal power supply and selectable line voltage. The rugged, all-steel chassis occupies 2U rack spaces and is intended for installation into standard 19-inch equipment racks.

Applications for the HQ-231 include live sound systems/PA, permanent or fixed installations, church, club and practice PA systems, DJ sound systems, home and project recording systems, and monitor systems.

Customer Reviews
4 out of 5 (28 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Know Your Situation"
Sound: Quiet in XLR balanced .Have not used it any other way. Feature: No accessories.Best feature are the frequency lights on each channel and the +-6 and +-12 selector. Ease of Use: Read the manual.it's easy Quality: well built but not for pro road use.shock mounted maybe semi-pro.Weekenders absolutely good to go. Value: They make a product,without an inflated retail price so they can sell it for half off and you think you're getting a deal.it's a 300.00 EQ thats worth every penny.you know your situation and if you need a 800.00 eq don't buy this one.if you need a good eq and don't have the tools to measure a room,get this one. Manufacturer Support: These guys make good stuff.No problems with their product for years. The Wow Factor: Sex appeal?you got to be kidding!technically its an EQ!!!!enough said. Overall: If I still traveled alot,I would upgrade.But this thing works well and didn't bust the budget.All things the same I would replace if fried or stolen.we play in rooms 300 people or less.

"Decent"
Overall: I Purchased it for my audio system at home because I need to keep my system balanced. It doesn't sound as good as the Ashly it replaced which was the same price. However, the Ashly developed a hiss problem. Pressing the buttons with the volume turned up can sometimes cause a "popping" sound so turn the volume down before pressing them. It doesn't always happen, but better safe than sorry. I am really not that impressed with the sound quality. My system actually sounds better without it. I bought it to enhance the lows and the highs. It does work well for the lows, but the highs sound better in the bypass mode than with the EQ engaged. It does appear to be well made and very solid. It is dead quiet. The XLR inputs don't lock in place. You are not likely to pull it out in a home system, but on the road, it could be pulled out if someone trips on the wire or if the unit is pulled forward with no slack left on the cord. I like the fact that the sliders are lit-up so you can see what position they are in when the room is dimly lit. I wish more companies would do this. I would like to be able to switch the filters out of the signal path. But it can't be done.
Style of Music: All types.
