Graphic Equalizer --Ugh

You ought to consider also the Behringer DEQ2496. It has a 31 band graphic equalizer, but also has a parametric equalizer, a 61 band real time display, auto-equalization, (neat!) and some other features. It costs,with the calibrated mic and cable, about twice as much, but still cheap by audiophile standards. The DEQ1024 seems to use the same 24 bit 96KHz digital stuff, which, to me, sounds good. I can't hear any difference when the digital processing is bypassed (A/D and D/A with the EQ flat).

Check them both out on the Behringer website.

Cford...Unbalanced in. Balanced out.

Newbee...If there is a "tape" loop that is a logical place to put it. However, the DEQ2496 has a bypass switch which is the functional equivalent of the tape loop. NOT having a volume control after the DEQ2496 simplifies some level setting aspects of using the unit.

As for switching it out when "not needed"... I find that its most important function is to equalize the room response, so it's always in. I had no idea the improvement possible by room equalization until I actually experienced it.

Of course there will be the anti-EQ, anti-digital, and anti-Chinese-made comments. This is why I suggested that the purchase (all $370 of it) be justified entirely by the RTA capability, which observes but does not affect the sound. I am sure that once you get your hands on the unit you will be curious enough to listen to it, and exercise the auto-EQ capability. Then, you decide.
