I am installing some in-ceiling speakers in a few rooms and need volume controls for each room (6 rooms total). As far as I know, I don't need impendance matching controls because I am using a 12-channels amp (Speakercraft BB1235).

Would one of the rotary volume controls on Monoprice be good?

Or would this be better?

Doesn't matter which one you pick.

Actually, it's primarily the way you connect the speakers that dictates whether you need any form of impedance matching - the basic concept is to present a viable load to the amplifier(s). If you are just running one speaker per amplifier channel, and they are typical 4 or 8 ohm loudspeaker units, like ifor said, it won't matter which of the two options you pick. If you decided to "pair up" speakers, so that multiple units share a common amplifier channel, then you'd need to get into impedance matching - having this flexibility would sway me towards getting a volume control with this capability.

I'm not familiar with your SpeakerCraft amplifier, but it will indicate somewhere (manual and/or rear panel) what its acceptable loading range actually is.

You probably know this, but the Monoprice unit actually does have impedance matching functionality too - both units you listed use internal jumpers to allow for a variety of speaker loads and configurations. There are some volume controllers that detect the loading & adjust the impedance automatically, but I always question the additional cost of these versus just switching jumpers.

So bottom-line is: both would do what you want (and give you impedance matching should you ever need it in the future).

So the $15 Monoprice one will work just as well as the $30 AudioSource? No point in really spending the extra money? Does one have better build quiality etc?

Short of seeing both units, I have no idea of the relative build qualities, but like I said, both are from reputable sources, so there is no 'wrong' choice. I personally would buy the MP unit - I've had nothing but good experiences with all the purchases I've made from them and the price difference, especially if you are buying multiple units, is compelling.

FWIW, I actually do have a MonoPrice volume controller, but I'm not 100% sure that it's the model you linked to - my unit has been installed in a bathroom ( = less than optimal conditions) for about 5 years and has performed flawlessly.

I did acknowledge your admirably succinct post! smile.gif

Sometimes it takes more than a "trust-me" type of reply...... and a more lengthy response is definitely preferable to working on a particularly onerous task I'm meant to be focusing on here in the office!

Sure beats working.....and I'm the boss!

So, how did it work for you?

Before reading this thread, I spend $45 on a Speakercraft volume control. Will be installing this weekend.
