Behringer DCX2496 EQ Review

[gp4Jesus]

It is possible to disable the filter.

Great! How?

Great! How?

In the filter menu, you go to the high pass and turn the knob all the way to the left. Then It will say "off".

Of course most equipment has some DC blocking that will have effect at very low frequencies usually below 20hz.

Ah, yes, Behringer. Still use it! This is the 'full stack' (attached) -
the SRC2496 (nice headphone amp that I use with HD 580s) but primarily to match inputs,
a DEQ2496 for Parametric Eq,
the DCX2496 for driver alignment, equalisation, and AK DAC output,
and finally the A500 amp(s).

Very useful for home-built speakers. Nowadays I just use it for sub-bass integration and timing.
But yes, there's better out there now.
In its day, a relatively cheap way to operate in the analog/digital domains.

Can be setup from a PC, though Win11 makes it tough to use right software and drivers via a USB-RS232 link.

Big thanks for your help. This will provide signal where it counts the most for this portion of the system

Yeah I aware and realize the value* of filtering at the extremes*. I believe dbx “cuts it” in a more “non-negotiable” way.
*prevents the less learned from destroying their gear; 20-20Khz

The flip side: the THX LFE bandwidth begins @ 3 hz. I don’t know a simple way for the DIY consumer to get around the above*!safeguards*

It still seems to be a pretty cheap option considering what it does and the performance isn't too bad either.

I just found one of these in my closet along with a DEQ2496, two items I misplaced years ago but were right under my nose the whole time in a box I didn't think they could fit into. I already had one DCX in service but that one I had modified by bypassing the output stages so the dac chip was running straight into the pre-amp. I decided to put this unmodified one in for comparison. I have to digitally attenuate by 20dB to keep the output stages from overloading my pre-amp inputs but it still sounds good - I think better than the one I modified. It seems punchier, more dynamic, with brighter and clerear hiighs. Voices have more presence. No idea if it really sounds different or if I'm just imagining things. In any case I liked the fact that it works and sounds good so I ordered some 20dB in-line attenuators. I'll give those a try and find out if I think they make any difference by allowing me to use more bits without blowing up my receiver.
