Introduction
Owner’s Reference A-100 Power Amplifi er
Thank you
Cool and effi cient
running
Power ratings
What you can
expect
Thank you for your purchase of the Trio A-100 power amplifi er.
The A-100 stereo amplifi er is a dual mono power amplifi er, capable of driving nearly every loudspeaker
load with ease and beauty. The Trio power amplifi er is based on ICE power switching amplifi cation
for the output.
The A-100 has two high effi ciency digital amplifi cation stages that allow them to run cool to the touch
even while driving demanding loads and should offer years of trouble free performance of the highest
standards.
Power ratings for the A-100 are 100 watts rms into 8 Ohms, 200 watts rms into 4 Ohms at less than
0.1% THD. For musical peaks, the Trio can produce up to 150 watts per channel into 8 Ohms and
300 watts per channel into 4 Ohms.
You should expect state of the art performance and sonics from any PS Audio product. The Trio
series products represent high value in terms of performance within their rated power levels and will
provide excellent results in either a two channel or multi-channel environment.

Location
Cautions
Isolation
Power Cables
Conditioners
Once your new A-100 Power Amplifi er is unpacked, you’ll need to fi nd a convenient place to set it.
There are several ways to mount the A-100 Power Amplifi er: on a rack shelf, on the fl oor behind the
loudspeakers or on shelf near your preamplifi er.
If the Trio A-100 Series Power Amplifi er is to be placed on the fl oor or carpet, make sure the unit is
not going to come in contact with water or cleaning solvents. Make sure the carpet does not interfere
with airfl ow to the amp.
The A-100 can benefi t from aftermarket isolation devices such as cones, spikes and Sorbothane
pads.
Once you have chosen the location for the A-100 you can use the supplied AC power cord to connect
it to the AC wall receptacle or you can use an aftermarket power cord and receptacle.
We strongly recommend the use of a PS Audio xStream Power™ AC cable and a PS Power Port™
AC receptacle to feed the A-100 power. While the supplied power cable is adequate for the task it is
not going to provide the best performance. Choosing any xStream Power cable will make a signifi cant
performance improvement over the stock power cable.
We recommend the use of power conditioning equipment, such as a PS Audio Power Plant, UPC200 or any of the Ultimate Outlet or Power Director series from PS. We do not recommend the use
of simple AC fi lter power conditioners not made by PS Audio as most of these will ”bleach” the sound
and rob the music or video soundtrack of life and dynamics. If you do not use PS Audio power
conditioning equipment, you would be advised to plug the GCA Power amplifi er directly into the AC
wall receptacle.
