We currently use Vision AV-1300/1301 around the site. But we are seeing some problems with a few with sound and the amp is at fault
What amplifier would you recommend for classroom use. (Most speakers are Visions 1300)

We have the same but the fallout is very high for modern electrical equipment at around 20% over 5 years. I've have been pushing for a standardised classroom system but the money's not available, so classes where the amp has failed are using any old domestic type amplified speakers I've been able to lay my hands on. And, there are no complaints. They are loud enough and easy to use.

We have some TOA A1712 units which we are removing as we now use the Frontrow Soundfield system. We may be selling these off if you are interested?

That would be too hard for the staff to understand. Just looking for something plain and simple

We also have some Cambridge Audio A1 V3 amps which are coming out. These are quite old but simple to use. All still work I think. These would be available as a batch lot for a small donation to school funds.

We had problems with a couple of Vision Amps, turned out that it was the Power Supply - PS casing was swolen, so i think some of the capacitors had popped inside.

we just like to know what people are running. I do like the look of the AV-1700. just seeing if there better value or anything out there,

Cheap as chips. Seems to be fine in use, and much better than the self powered PC speakers that ARE NOT loud enough in a large room.

Oh... might have to do a check on these at our place. Not had any reports of ourd failing yet.

True. They do struggle a bit in the O2 arena but the big advantage with PC speakers in classrooms is you don't get called out to turn the source selector knob.

We've settled on Behringer MS40s for our classrooms now. Kinda pricey but they work very well in a classroom. No need for separate amp or line switching.

But if you have two sources connected, you loose volume as teach source is driving into the output of the other device. Yes, we still have DVD players as a back-up for when the PC dies, the servers won't log the users on, or the log-on process is measured in weeks rather than minutes.

I started to standardise on these (well an older model) - CIE-Group Clever Little Box In-wall Stereo Amplifier 2x 12W AVID great little units and the new models are even better with bluetooth

We install these on a daily basis now and have received great feedback from customers. They cost around £120 including the wall amp and either wall or ceiling speakers.
