ART HQ-231 DUAL GRAPHIC EQ w/FDC

The newest member of the HQ SERIES: HQ 231. features ART?s FDC? Feedback Detection Circuitry.
The A R T 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, Ό? 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? 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.

DBX 2215 Dual 15-Band Graphic Equalizer with Noise Reduction

 It's amazing. One little button. So much effect. dbx? Type III? Noise Reduction is an entirely new concept... virtually instantaneous encode/decode within the circuitry of the box. We started out to build the finest EQs possible, boxes with the heritage and performance to rival our famous 30 Series EQs. And to no one's surprise they came out awfully darn good. (Ask to see the Audio Precision plots compared to the competition.) But then, Roger (our chief engineer, a nice guy, as far as engineers go) got the crazy idea of putting this new noise reduction stuff in the box. We listened to it and were amazed. The EQs sounded great without it but with it the performance was nothing short of incredible. Check it out yourself and see.

But hey, Roger wasn't about to stop there. PeakPlus? Limiter. Who knows more about limiting than the folks at dbx; nobody... that's who. So when the guys were developing this new series of EQs they wanted something that would be unique to these EQs. That's when Roger got another one of his bright ideas and said "I bet they'll work a lot better if there's a cool limiter built in." Next thing you know, all the guys are in the studio amazed at the new limiter Roger had designed specially for the 20 Series. Once again, hearing is believing... With a threshold range of 0dbu to plus 20dbu, the patent-pending PeakPlus limiter is designed to tame your program material from the subtlest nuances to the rowdiest hits. Also, the four stage LED ladder gives you a great visual indication as to what the limiter is doing.

20 Series EQs. You used to have to settle for second best in a reasonably priced EQ but not any more. With the new 20 Series from dbx Professional Products you get a great EQ circuit, a graceful yet powerful limiter and the revolutionary new design of the Type III Noise Reduction. Check out the dbx 20 Series graphic EQs at your pro audio outfitter. You'll see, with the 20 Series EQs you get MORE!!!

Μονοκάναλο equalizer εμπνευσμένο από το κλασικό Neve 1073, με ζεστό και μουσικό ήχο σε πολύ προσιτή τιμή.

Το EQ-73 αποτελεί ουσιαστικά το eq section του Neve 1073 χωρίς το φίλτρο high-pass, ενώ έχουν προστεθεί περισσότερες συχνότητες οι οποίες λειτουργούν με ρυθμίσεις stepped στα πρότυπα της vintage μονάδας για καλύτερη δυνατότητα ανάκλησης των ρυθμίσεων. Συνολικά, το εύρος των ρυθμίσεων είναι από 20Hz εως 24kHz με κέρδος +/-15dB για τις δύο χαμηλότερες μπάντες και +/-18dB για την υψηλή μπάντα.

Συνδυάζοντας το Pre-73, το EQ-73 και ένα Unite Rack, έχετε την αυθεντική μονάδα Neve σε ασυναγώνιστη τιμή!
