preamplifier after preamplifier?

Do you have a tape out on preamp 1? If so use that to drive preamp 2. Then use preamp 2 for volume control for subs. There are a few postings about this type of hookup.

This is the hookup I use for controlling my passive suds. Tape out to preamp 2, then to my external crossover, then to DSP for subs only. then to dedicate power amp for subs.

Hi Guys,

Signal purity to be highest goal here.

any preamp externally on top of another or dsp will work against it.

Solution for it in case of using digital front end with both volume control and a DAC, such as a CD player, connect player’s RCA outputs to subs directly and player’s XLR to your preamp. Or use Y splitter at player’s RCA Outputs.

so any kind of combination with volumes of your speakers and your subs is possible.

I do this for years now with my Nagra system. Very exiting every session…

Enjoy the music.

2nd advantage of this solution, you always need to deliver signal to subs as early as possible since sub drivers are not fast in reaction. So your speakers receive the signal little later than subs. Result is matching phase of both drivers (normal speakers and subs) if sub signal arrives at your ears too early use subs’s delay or phase knobs to adjust.

works flawlessly.

any solution with dsp or 2nd preamp cannot beat above.

Enjou the music…

Didn't Elizabeth have three preamps daisy-chained together at one point?

I wrestled with this for years. Bought a dbx drive rack 360 and love it. Very versatile. Check it out. Control all speaker volumes, delay, parametric/graphic eq-the list goes on and on.
