1993-Vintage PPI Amp Specs needed

fixitnate · 6th May 2007, 09:20 PM

Having searched the forums to the best of my ability and not having found anything, I'm starting this thread. I have 2 PPI amps from 1993 or thereabouts... one A100 Art Series and one APA200ix Sedona. I'm fairly sure about the Sedona specs as I've used it recently to put 200W through 4 Ohms-worth of subs, but wouldn't mind a full spec listing. I can guess, please correct or fill in the blanks:
- 2 x 100W @ 4 Ohms
- 2 x ???W @ 2 Ohms
- 1 x 200W @ 4 Ohms

As for the A100, I can only guess based on some specs that I found that may or may not apply to this amp, please correct or confirm:
- 2 x 50W @ 4 Ohms
- 2 x 75W @ 2 Ohms
- 1 x 100W @ 4 Ohms

I would appreciate any help as I came into these beauties without the manuals.

I am not familiar with these particular amplifiers but I can tell you that the 100 IS rated at

2x50 at 4 ohms which would be 1x100 at 8 ohms

The 2x75 at 2 sounds about right but this would translate to 1x150 at 4 ohm

As for the 200 if using the same math for it

2x100 at 4
1x200 at 8

2x150 at 2
1x300 at 4

Having actually seen the 200ix manual at some point in time, I'm pretty sure it is rated at 1 x 200W @ 4 Ohms when the 2 channels are bridged, and that is actually what I have used it for. Not too sure about your math or assumptions on some of the stuff...

The math is correct. An amps 4ohm bridged power is the same as the sum of it's 2 stereo channels at 2ohms. Thus 75x2 at 2ohm = 1x150 at 4ohm. The question is... What is the 2ohm stereo power per channel? Some amps double, some amps gain no power at all. It depends on the design... How regulated the power supply is...

I have a PPI brochure from a long time ago, not really sure of the date. On the back page there are specs, yours are as follows:

A100.2
stereo 4 ohms, 11 - 15 vdc, 2 x 25 watts
stereo 2 ohms, 11 - 15 vdc, 2 x 50 watts
bridged, 4 ohms, 11 - 15 vdc, 1 x 100 watts
power fuse, 30 amp

200iQx
stereo 4 ohms, 14.4 vdc, 2 x 100 watts
stereo 2 ohms, 14.4 vdc, 2 x 165 watts
bridged 4 ohms, 14.4 vdc, 1 x 330 watts
power fuse, 35 amp

With the art series amps the model number is the total power at 2ohms therefor a 100 is 2x50 @2 the 200 was 2x100 @2 etc....
