The Ashly TRA-2150 is a 2-channel convection-cooled rackmount P.A. or installation power amplifier housed in a rugged 2RU metal chassis, offering an output of 80 Watts per side at 8 Ohms, designed to drive 4 and 8 Ohm loads and transformer coupled 70V and 100V lines simultaneously. The coupling transformers are internally mounted.
The TRA-2150 incorporates a switch-mode-power supply and Class-D amplifier circuitry, providing a power-efficient solution. The low-noise unit features a switchable HPF filter and selectable gain sensitivity, turn-on delay DIP switches with up to 8 seconds of delay available, and rear-mounted set-and-forget gain controls.
The TRA-2150 is equipped with an internally switchable 120V/240V power supply, extensive protection circuitry, and standard Euroblock inputs along with screw terminal outputs.
