My friend needs an amp with two seperate volume controls. She runs a cafe that has an upstairs and a downstairs. She would like to have the same music in both but be able to turn the volume in each room up and down independantly. Is there anything like that out there?

Sounds like you need some kind of PA amp or a mixer/splitter thing to go in between the amp and speakers.

Google this:

QSC GX5 Professional Stereo Power Amplifier

Tried to copy the link, but my phone is being crap.

Try Googling “inline speaker volume control”

Some home cinema amps have dual zone setups, so you can play one source in one room and another source in a different room. You can also get seperate volume controls that you just put in-line with the speaker cables.

Excellent! Thanks for all your help, checking them out now..

Found these. Seems to be about right!
