Rolls RA170 Rack Mount 70V Power Amplifier 70 Watt 1U
Rolls RA170 Rack Mount 70V Power Amplifier 70 Watt 1U is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from SUPERB SOUND QUALITYI bought this about a month ago to replace a piece of junk Pyle amp that never sounded good and finally failed.This amp is like night and day. Frequency response is incredible, distortion is non existent even at very low frequencies. We use this to power 20 speakers at 10 watt taps, so even though the power of this amp is rated low, it is more than enough to drive all these speakers without a problem. I highly recommend this amplifier, it is professional grade.

How many speaker zones will this drive?

Asked by: Johndh
As a 70v amp, this will drive as many speakers as you would like as long as they are all 70v. You do not want the tap settings on all the speakers in the system to add up to more than about 80% of the amplifiers RMS output power.
