Specifications

Any existing audio/video source—an HDTV satellite receiver, a progressive-scan DVD
player, a DVD-Audio and/or SACD player—connects easily to the ATP8700. Balanced
XLR-type outputs for every channel make it ideal for use with ATI’s AT3000 and AT2000
Series Pure Balance
®
amplifiers.
AT3000/AT2000 Series
Engineers, reviewers, and home theater enthusiasts may often disagree, but when it comes
to amplifiers, there is one fact on which they all find common ground: the best possible
design is the fully differential balanced amplifier. A fully differential amplifier is basically
two separate amplification circuits per channel. One circuit amplifies the positive half of
the audio signal, while the other amplifies the negative half. The benefits of this design
are tremendous. It automatically rejects any noise coming in from external sources, such
as radio-frequency and electromagnetic interference. It eliminates hum and reduces
distortion. It also doubles the slew rate (speed) of the amplifier, for better reproduction
of high frequencies and better transient performance. We call this technology Pure
Balance
®
, and we use it in two of our amplifier lines: the AT3000 and the AT2000 series.
The result of Pure Balance technology is breathtaking. Acoustic instruments sound so
natural and clear, you may think you’re hearing a live performance. The rich ambience of
concert halls envelops you as never before.
Although some home theater amplifiers have balanced, XLR-type input
connectors, most simply convert the balanced signal to unbalanced in the first
amplification stage—and limit the benefits of a balanced connection in the
process. Not Pure Balance amplifiers. Pure Balance amplifiers keep the signal
balanced all the way from the XLR inputs to the speaker terminals.
With substantial power on tap—300 watts per channel for the AT3000 series, 200 watts
per channel for the AT2000 series—both amplifiers have the muscle to power the largest
home theater systems. In particular, the AT3000 series produces enough power even for
capacious screening rooms. Both amplifiers are available in any two to seven channel
models from the AT2002/AT3002 to the AT2007/AT3007. Because each amplifier channel
resides on a separate, plug-in module, upgrades are easy.
You can start with, say, five channels and add two more if
you decide to move up to Dolby Digital EX
®
, DTS ES-Discrete
®
or other 6.1- and 7.1-channel surround-sound technologies.
We supply the AT3000 series with a power cord that fits
only into a 20-amp electrical socket. This amplifier is so
powerful it cannot reach peak output from a 15-amp circuit.
The power cord is designed for 20-amp use, providing a more
r
obust connection to the amplifier than a 15-amp cord can
offer. The AT2000 series uses the same 20-amp connection
at the amplifier end, but substitutes a 15-amp plug.
Listen to the AT3000 and AT2000 series amps.
We think you’ll agree that no other fully differential
amplifiers in the world can beat their performance
and power—or their price.
