Calibration on 2CH?

[scanido]

Hi There,

I'm about to purchase an SPL Meter and was wondering if calibrating the LEFT and RIGHT Channels are necessary for 2CH audio?

I understand this is more important when calibrating 5.1/7.1 home theatre, but what about 2CH?

Thanks,
Steve

If your receiver allows you to set levels for each channel, then it is worth doing. I don't know of any two channel setups that allow for that in the analogue domain, though. I have a DVD player that can be directly hooked up to an amplifier and that has level setting functions, so, in theory, I could do it for a two channel setup, but I don't know of any two channel integrated or pre-amp/amp or receivers that can do this.

I was thinking the same thing and actually tested this. When i set my Rotel RSX-1057 speakers levels I intentionally set the right speaker to -10db to see whether or not the levels are active during 2CH Bypass.

After testing they are actually active. When set to '2CH BYPASS" the right speaker was noticeably lower in volume in comparison to the left speaker.

Do some reading up on the Behringer DEQ2496. You can do some very top notch equalization/calibration with that. Thomas and other have discussed it somewhat in the DIY area, and there are numerous other discussions of using it this way a google away.
