The TRA-Series of amplifiers incorporate switch-mode-power supplies and Class-D amplifier circuitry, providing an extremely power-efficient solution for constant voltage or low impedance applications.
Features include: convection cooling, extremely low noise, an internally switchable 120V/240V power supply (internal), extensive protection circuitry, euroblock inputs and screw terminal outputs.
TRA-Series amplifiers are housed in a 2RU chassis with the capability to drive four or eight ohm loads and 70V and 100V constant voltage lines simultaneously. The coupling transformers are internally mounted.
Front panel features include: mains power switch and an LED signal level meter indicating 24dB, -18dB, -12dB, -6dB, -3dB and clip alert for each channel. Rear panel features include: level attenuators for each channel, rear panel switches to select between two choices of input sensitivity, remote power turn-on/off and adjustable turn-on delay up to eight seconds.
