Title: Stereo attenuator/amplifier
Post by: Slim-Shaddy on October 19, 2013, 03:07:44 PM

The zone 2 outs on my new preamp are fixed at 2 volts. I need a piece to run between the preamp and amp that will not only attenuate the signal, but also amplify it. At the fixed output level it's moderately loud, but I could see myself wanting it louder, hence the need for amplification.

Any ideas?????

Thanks,
Sparky

Would a headphone amp do the trick?   No idea how many volts they run at.

Got a spare integrated amp around?

Another preamp.  Your current preamp is basically sending a line level signal to the second zone.

If you need something in the meantime, I have an Onkyo Integra A-8067 that I'm not using. You can borrow it until you find something (another preamp) that solves your issue.

I have a spare preamp (that is dual zone and has a volume on the second zone), but I like this one better. Just a really stupid design. Why a zone 2 without a volume?? Thanks for the suggestions, but the search continues...

What is your new pre-amp?

A second zone with only fixed voltage is like a separate tape buss, and therefore mislabeled IMO.

I guess I could just get into a pro amp with controls. Sound quality isn't a huge issue, it's just powering a pair of outdoor jbls...

If the speakers are decently efficient.....how about a T-amp with volume control?
