These 2 rack space amplifiers utilize Ashly's 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.

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 TRA-4150 is 4 channels with 150 watts per channel. The 150W models are capable of driving 25V Constant Voltage lines using the direct coupled 4 Ohm output.
