Pyramid PA Paging Amplifier 100W Rackmount
Pyramid PA Paging Amplifier 100W Rackmount is rated 4.3333 out of 5 by 9.
Rated 4 out of 5 by from Good bang for the buckBought this looking for a cheap replacement to run a few horns at a local baseball field. Not a bad integrated amp. To do better you may end up spending 3x the money. Price point vs power is the major pro. I did find a few cons though. First, it playes music good enough but the mic inputs seem to have very little headroom. An animated announcer will easily find himself in the clipping range. Second, the auto ducker on the first mic channel also adds some noise. Not bad but still noticeable. This only effects the fist mic input however.

Rated 4 out of 5 by from Pyramid PA305I selected the Pyramid PA305 for an installation in a mid-sized venue. They do some meetings and poetry readings, etc. They also do occasional large music events that I usually mix with a carry in system.The Pyramid PA305 works great, lots of power to drive two two-way 10"/4X10 horn cabinets. The ability to mix four mike inputs makes it flexible enough. The CD/Aux input offers them the ability to do background or foreground music from a wide range of sources.A minor drawback: the auto dunking of the CD/Aux input when there is signal on the mike one input works, but would work better if it had a time delay response. As one is speaking, music returns to full level on every breath or pause.

Rated 5 out of 5 by from Excellent addition to our sound systemJust bought this to power a few speakers in our classroom. Definitely going to get another one for our other classrooms.

Rated 2 out of 5 by from Good while they workThis is a nice solid amp that gets the job done for not much money. However . . . when they die, there are no schematics to repair them and Pyramid does not even reply to support emails. You need to determine if you want to buy disposable amps.

Rated 5 out of 5 by from Super value and sounds great!I'm using this with a Sonos system driving 10 TIC outdoor speakers. sounds awesome. Super easy set up with the 70V output. Couldn't be happier.

Pyramid PA Paging Amplifier 100W Rackmount

Currently I am using a Radio Shack PA MONO AMP 40W for my office with speakers in each room about 12 speakers,,, but getting a lot of distortion and noise. Can I use this amp? I will be connecting a SONOS player into the AUX input. Thanks in advance

Asked by: dg2Goshen
As long as the speakers are 70 volt and the wattage taps add up to about 80 watts or less this amplifier will work fine for that application. You generally do not want the tap settings to add up to more than about 80% of the amplifier power rating, so you may be able to change the taps on the speakers and get rid of distortion that way, assuming that is the cause of the problem.

can I connect 8 ceiling speaker to this unit and how.?

Asked by: desk
This is a 70 volt amplifier so as long as they are also 70 volt speakers with matching transformers, you would just connect them in parallel and tapped at no more than 10 watts each.

When 2 units are connected with mix bus, does it really double the power?

Also, does a mic plugged into one unit work through both? Finally, should the speakers be split between the 2 units in a 70-volt configuration?
Asked by: bclarke675
You cannot get more power than the amplifier is rated for. Depending on the source, it is possible to get a slight boost of input sensitivity using two inputs as opposed to one but this does not change the output power.
