Bargain interconnects to tame treble & boost bass?

OK, next question... Does the Behringer DEQ2496 only produce sound when operated in bypass mode when both inputs and outputs are in the analog domain? I must have tried every conceivable configuration over a 2 hour period last night, and was only able to get sound when I operated in "Bypass All" mode.

Must I use digital input in order to EQ the sound, without a microphone/RTA?

Initial impressions are that in "Bypass All" mode, the sound does lose a bit as compared to not having the unit in place - most noticeable is a shaving off of some bass heft and weight - which conceivably could be added back in via EQ. A slight amount of noise and hiss is added in, but nothing akin to a normal equalizer, and presuming I can tailor the sound to my tastes/room, I could live with it.

Trelja...Are you using analog or digital input? On the I/O menu make sure the proper one is selected. If you are using digital you must configure the Behringer for the appropriate sample rate (I/O menu again). If the sample rate is wrong the outputs will be muted.

My unit is dead quiet. The S/N spec is 113 dB. You probably have too much gain following the Behringer. Remember this is a pro sound unit and likes to run at higher line level than the typical home audio equipment. A low level input will also result in not using all the 24 bits of the converters, which probably affects sound quality. Are you using single ended or balanced interconnects? I use single ended for input and balanced for output. If you use single ended make sure that the (-) pin is grounded.

I understand your frustration! This is a very complex and flexible unit, which is good, but it does take a while to figure out how to use it. The real fun will start when you get the mic.

Eldartford, I got the unit working for me last night. Like a complete and total IDIOT, I had the inputs going to my integrated, and outputs going to my CD player. After a couple of minutes of playing around, only being able to get output in "Bypass All" mode, I checked the cables, fixed the stupid mistake, and all worked perfectly afterwards.

Funny that I spent all my initial effort on the female XLR adapter for the outputs, and ended up routing the cables to the wrong place. The inputs are a pair of ICs with RCAs on the output of the CDP and male XLRs into the Behringer. From the outputs of the Behringer, I have a Cardas female XLR - female RCA adapter, then a pair of ICs, with RCAs on each end running into the integrated.

I didn't spend enough time afterwards to gauge the sound, but I was able to change things via the DEQ operation, which left me as pleased as punch as it's the goal of an EQ device. Tonight, I'll sit down and listen more critically, and try to ascertain its effects sonically. After that, I'll switch out the integrated and install the AtmaSphere monos. I have a different pair of male RCA - male XLR cables that'll go right into the Atmas. The CDP is variable out via the tube output - currently set at the 11 O'Clock position.

Nothing is being overdriven or underdriven in my opinion, and so far I've listened at quite low levels. My impressions of the sound in "Bypass All" mode are that I agree that the unit is dead quiet, it's just not 100% transparent. I hope that distinction is not lost on anyone. Along with the aforementioned minor reduction - I'm talking very slight, and totally correctable via a bit of EQ I'll add in later. In DEQ mode, it seemed the additional circuitry made itself known even moreso, but I don't want to say too much yet.

Please understand that the level of resolution I have is such that changes in cabling, tubes, etc. are instantly apparent, and this is no different. Still, it's night and day better than any other equalizer I've ever tried. It also easily, and I do mean easily, eclipses any preamp (Blue Circle, Cary, CAT, Joule, Jeff Rowland) I have installed in terms of transparency, detail, resolution, dynamics, etc. - unlike any preamp I have tried, it did a far, far, far better job of not adding or taking away anything to or from the sound.

I'm waiting on the ECM8000 microphone you recommended (Thank you!), and if the room EQ functionality can fix the issues I have had in there, which room treatments helped with, but did not solve, I'll be as big a proponent of the Behringer DEQ2496 as you are. Over the past four years, I have tried all manner of cabling, tubes, CD players, preamplifiers, power amplifiers, and speakers before coming to the conclusion that the room is the issue - and the most important link in the audio chain. So many of us have MAJOR room issues (I have one excellent room, and this lousy room), including a guy I know who is considered one of the biggest gurus in audio, that finding a component that can correct the problems is a far more important purchase than any room treatment, cable, preamp, or front end source.

Trelja...It took me months of fiddling around to learn how to set up and use the DEC2496. And I are a engineer!

The line level setting is one thing that I found very important, but which many users probably don't bother with. You can monitor the input (electrical) levels using the METER mode. It will, among other things, log the maximum level seen during the course of playing a CD. The procedure I used is as follows. It applies when the Behringer is between the preamp and the power amp, and is cited to illustrate the basic idea. (If you use the digital input this may not be necessary).

1..Mute, or turn off, the power amp.
2..Play a CD that includes some loud parts. (I actually used a test CD put out out by Denon that includes test signals at specific levels like -20dB).
3..Crank up the volume control until the level runs around -20 dB on the green LEDs. (Remember this is dB down from the 0 dB reference). If you use the Denon test CD this -20dB setting can be done exactly.
4..Back off the volume control a bit, and then turn up the power amp gain to what you think is loud.

In my system this setup procedure results in typical music signal running about -20 dB much of the time, and the peak for a whole CD being -6dB or less for both channels. I never see CLIP. However you do the setup, this should be the goal. The basic idea is to make the MSB (bit 16) of a CD correspond to the MSB (bit 24) of the Behringer. Hopefully this will happen automatically if you use the digital input.

Yes, a lot of subletys to the DEQ2496, Eldartford. Thanks for making my learning curve a lot shorter! It always pays to follow someone who has already conquered the learning curve.

Last night, I spent a good amount of time with the Behringer, first with the integrated, then my monoblocks. After listening, I must say you are right, the active EQ seems to add nothing more than the "Bypass All" functionality, which is a true accomplishment. No, it's not 100% of what is going into the unit, but it's sooo close, I can think of no high end audio preamp that even gets within the same area code as the Behringer.

With the Atmas, I was able to dial in a bit more upper bass, while cutting back on things a bit around the crossover of my loudspeakers and smoothing out the sound. Now I just need the microphone so I can run the curve of the room, and have the unit apply the appropriate compensation.

Seems like the Behringer is going to be staying, and it will hopefully cure my room anomalies. Right now, I can't think of too much available in today's high end market at $300 that will solve more problems than the Behringer. Problems that many an audiophile aren't aware of, ignore, deny, or go to a lot of trouble to apply room treatments that may create as many issues as they solve. If things continue to progress as they are, the Behringer DEQ2496 is certainly going to have my recommendation.

Thank you again!
