I know this is heresy, but...


I am interested in adding some sort of equalization within my system....tone controls for lack of a better analogy. I know that years ago Audio Control used to make a band equalizer. Anyone out there making that sort of device today? Basically I am looking to add a little more bottom to my system without adding a subwoofer or adding a lot of noise to the sound. Thoughts?

I have an Audio Control Richter scale, which is probably what you refer to. However the Behringer DEQ2496 is far superior.
Benjamin7...Actually, while an equalizer is undoubtedly the best way to rebalance the sound of a particular disc, it is not very convenient. Tone controls (remember those) are best for this purpose. They are also rejected by many audiophiles who are still living in the 1950s when tone control circuits were primitive and caused distortion. The best application of an equalizer is to fix problems that don't change from disc to disc. An exception to this rule would be a digital unit like the DEQ2496, which allows you to store and recall many different EQ curves at the touch of a button.
Dpac996...The DEQ2496 has balanced inputs and outputs, but can also be connected single ended either input or output, or both. It automatically detects what you are doing and sets its gain accordingly. I use it single ended in from preamp, and balanced out to power amps. I had unbalanced interconnects made with RCA on one end and XLR on the other so as to avoid using adapters.

Opinions about "transparency" range all over the place, and I suggest you ignore them all. (Except mine of course...very transparent). The darned thing is so inexpensive that you can get one and form your own opinion.

Warnerwh...By admitting that the Behringer is "transparent" in your system you have admitted that your system is inferior :-(

My condolances, and, as Rauliruegas says. "enjoy the music".
Shadorne...Rives audio, who certainly are great believers in room treatments, will tell you that low frequency problems can't be fixed this way. That's why they developed their PARC equalizer. The only really "correct" way to deal with LF room modes is to build a special room with ideal dimensions and no square corners. But few have the time and money to do this.
If you put the DEQ2496 between the preamp and the power amp its A/D will be working with only a few low order bits. The advantage of 24 bit hardware will be lost. You may not like the sound.

The solution to this is to attenuate at the input to the power amp so that the signal going through the DEQ2496 is at a healthy level. Set things up so that the peak level throughout a CD, indicated by the DEQ2496, is about 3 dB below cliping.
