preamplifier after preamplifier?


Hi.

I have a preamplifier and a poweramplifier I am very satisfied with.
The preamplifier is connected to the poweramplifier and the powerampfiler is connected to speakers,
The connection between the pre- and power-amplifiler is also spited to two active subwoofers.

However, I miss the option to control my sub-woofers volume relative to the speaker volume.
My pre don't have any settings for tuning this, just volume +/-

Can I connect a Second pre-amp with independent volume before the sub-woofers? will this cause any damage or problems?
It might be easier to understand this drawing:


Pre #1: pro-ject pre box s2 digital
Pre #2: AIYIMA Tube Pre

on my SVS sub you can run speaker wire from the power amp speaker output to the sub and volume will be controlled by the preamp volume.  thety call it high level input on the sub.  

Not possible because the first preamp output will be too high like firca power amp and not for a preamp.    The second preamp will need a low output like from a source example Phonostage ,CD PLAYER or DAC . unless the first preamp has a source direct out.  

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.
