lowering gain on Aleph 3

[hancock]

I've got way too much gain n my system and would like to take some out (maybe 14dB). I figure the most effective way to do that would be to decrease the gain on the Aleph 3. Can anyone tell me how to do this?

thanks a lot, John

Lower gain

Change the ratio between r104 (10K) and r102(1k). The gain is 20*Log(r104/r102) or 20 in this case.

Reduction of gain by increasing feedback might affect the original sound.
Another idea could be installing a voltage divider (attenuator) somewhere between pre output and Aleph 3 input . . . ?

I think Aleph 3 would be the last component in your set up to lower the gain in.

I don't know how efficent are your speakers (maybe 105db), but Aleph 3 itself doesn't have high gain. I think it is lower than most average power amps.

Try to lower your gain in your pramplifier at first (if it offers this oportunity), but if you can't do that, use the resistors L-Pad at the input of your preamplifier calculated for desired loss.

Build a Balanced Zen Line Stage (BZLS, BOSOZ).

It has a wonderful array of adjustments
