Product Description

The Ashly TRA-4075 is a 4-channel convection-cooled rackmount P.A. or installation power amplifier housed in a rugged 2-RU metal chassis. The unit offers an output of 40 Watts per channel at 8 Ohms, and is designed to drive 4- and 8-Ohm loads and transformer-coupled 70V and 100V lines simultaneously. The coupling transformers are internally mounted.

The TRA-4075 incorporates a switch-mode power supply and Class-D amplifier circuitry, providing a power-efficient solution. The low-noise unit features a switchable high-pass 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-4075 is equipped with an internally switchable 120/240V power supply and extensive protection circuitry along with standard Euroblock inputs and screw terminal outputs.
