2 to 7 Channels - 180 Watts/Channel
The AT1800 series is the direct outgrowth of the award winning AT1505
5-channel amplifier that led the home theater industry in audiophile-grade
sound and performance at a value price. The AT1800 is available in 6
configurations from the AT1802 2-channel model to the AT1807 7-channel
version. Power is 180 Watts
RMS/channel into 8 ohms from 20Hz to 20kHz
with no more than 0.03% THD and I.M. distortion. Each model comes equipped
with two toroidal transformers making upgradeability easy via the addition
of a plug-in module. Other features making it installer-friendly are: a
detachable IEC power cord, optically coupled protection circuits, soft-start
circuit and convection cooling eliminating the need for fans.
See below for additional features common to all ATI models:
| Remote Trigger: |
Activated from 3.3VDC to 24 VDC via a heavy-duty relay |
| Protection Circuits: |
Optically –coupled with full automatic reset. |
| Toroid Transformers: |
40% more efficient than EI type. Separate bi-filar windings for each
channel guaranty lower noise and crosstalk. |
| Circuit Boards: |
Double-sided, FR-4 glass-epoxy, computer-grade boards are assembled
in-house. |
| Soft Start Circuitry: |
Ultra soft turn on reduces in-rush current to a minimum. Multiple
units can be turned on without tripping circuit breakers eliminating the
need for sequencing. |
| Power Transistors: |
High-current, bi-polar output transistors with active bias circuits
result in effortless operation. |
| Power Cord: |
Detachable, 3-wire cord, 15 amp circuit. |
| 7-Year Warranty |
Parts and labor against defects in parts or workmanship. |
| Dimensions: |
17"w X 7"h X 16"d (chassis)
weight - 50 to 93lbs (model dependent) |

Made In The U.S.A.
The U.S. has always led the world in power amplifier technology, and still
does. All ATI products are manufactured in Southern California in a modern
50,000 square-foot facility to exacting design specifications and rigid
quality control. ATI manufactures all toroid transformers and assembles
all circuit boards in-house. We use computerized Audio Precision test
equipment to test each stand-alone amplifier module (DMC2) as well as the
completed unit. This control and scrutiny of every phase of manufacturing
guarantees unit-to-unit repeatability and a lifetime of accurate sound
reproduction.
