4 x 75 watt @ 4 ohm 70V, 100V amp.
The Ashly TRA-4075 is a 4-channel convection-cooled rackmount P.A. or installation power amplifier housed in a rugged 2RU metal chassis, offering an output of 40 Watts per channel 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-4075 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-4075 is equipped with an internally switchable 120V/240V power supply, extensive protection circuitry, and standard Euroblock inputs along with screw terminal outputs.
