The TRA Series amplifiers utilize Ashley Audio's advanced, efficient amplifiers - perfect for low impedance and transformer isolated 25V, 70V or 100V installations with modest power requirements.

All TRA audio controls are on the rear panel. 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.

This 150W models is also capable of driving 25V constant voltage lines using the direct coupled 4 Ohm output. TRA Series amplifiers incorporate a switch-mode power supply and Class-D amplifier 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. Of course you get the reliability, superior sonic quality and rugged construction you've come to expect from Ashly.

TRA Features:

• Convection cooling
