| AT 1800 Series 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 180WRMS/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. |
| 7-Year Warranty | Parts and labor against defects in parts or workmanship. |
| Dimensions: | 17"w X 7"h X 16"d (chassis) |
