TRA Series Amplifiers utilize our advanced, efficient amplifiers perfect for Low Impedance, 25V, 70V or 100V installations with modest power requirements. They also feature a switch-mode power supply with Class-D circuitry, providing an extremely power-efficient solution. All TRA Series amplifiers are convection-cooled, so there’s little maintenance after the installation, and no annoying fan noise.
Choose from 4 models available in 2 and 4-channel configurations with power ratings of 75W and 150W per channel at 4 Ohms, 70V and 100V. A 6-step LED meter for each channel lets you monitor all levels. TRA amplifiers can drive 4 or 8 Ohm loads and 25V or 70V and 100V Constant Voltage lines simultaneously. Output transformers are internally mounted. All TRA audio controls are on the rear panel.
The 150W models are capable of driving 25V Constant Voltage lines using the direct coupled 4 Ohm output.
