The TRA-Series of amplifiers incorporates switch-mode-power supplies and Class-D amplifier circuitry, providing an extremely power-efficient solution. Four models in each series are available in two and four channel configurations with power ratings of 75W and 150W per channel. 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 transformer coupled 70V and 100V 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 and HPF frequencies, remote power turn-on/off and adjustable turn-on delay up to eight seconds.
