I'm in the process of integrating my Behringer DEQ2496 Ultracurve Processor into my system.
It's basically because I have quite an image unbalance in my listening room due to the curvature of the ceiling and unavoidable unsymmetrical placement of the speakers.
It's not severe but enough to notice some drum kits sit off to one side (the left) and there is generally a bit more energy coming from that corner of the room which makes vocals etc a bit more pronounced.
Using the parametric EQ function on the left channel only (it operates in dual mono) to cut certain frequencies across the frequency spectrum (so one at 50hz, one at 120, one at 2000 and one at 10000) with wide slopes by between -1.5 to -3db, has a significant effect and shifts the image back to dead center. I've still to absolutely nail it but it's very close indeed. All the processing is done in the digital domain with the source signal coming from my streamer into the DEQ2496 then into the Mutec MC3+ and then on into my DAC.
A few more very specific 'cuts' in the EQ band will render the presentation perfectly balanced. In fact the overall sound is actually much more natural as I think some of the frequencies were being exaggerated due to the proximity of the left speaker to the corner, so it sounds a lot more natural and in fact with more bass and impact, likely due to less 'smearing' of the frequencies and nodes collecting in that corner.
So that sorts the digital part. Now onto the vinyl.
The effect is not quite so severe as with the digital, probably due to the vinyl's reduced frequency range and slight less 'precision'. My vinyl setup is by no means approaching great, but it's not half bad.
The DEQ2496 also has analogue inputs and outputs (XLR in/out and RCA out) so I can take the signal from the phono stage, perform a similar EQ processing job using a band EQ and hopefully obtain a similar result. I haven't tried this yet as I've actually just thought of it and have to make up some more XLR to RCA cables to accommodate the setup.
Just wondered if anyone has had to do or experienced anything similar with their setups. I was looking into Dirac software etc but to be honest the results I'm getting using this cheaper (but no less capable) DEQ are pretty much optimum from what I can hear. Things are sounding really 'right' with much more space between instruments and overall a less congested sound.
Am I committing audio blasphemy (especially in the analogue setup)? If so I don't really care as it just sounds so good to be honest.
Any comments welcome.
Right, off to make some cables . . . .
