TRA-2075 Two-channel, 75W/ch @ 70V, 100V and 4 ohms	Data Sheet Hi-Res Photo Front Hi-Res Photo Rear	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. 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 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. • 2RU Chassis • High Efficiency Switched Mode Power Supply • Class-D Output Circuitry • Internally Mounted Vonstant Voltage Transformers • Input Attenuators • Input Sensitivity 26dB or 36db • Remote Power Turn-On/Off • Adjustable Turn-on Delay • Convection Cooled • 6-Step Signal Level and Clip LEDs • Safety/Compliance: cTUVus/FCC, CE, RoHS
