Ashly's TRA-4150 expands on the SRA's concept of "the right
amp for the job." These 2RU amplifiers utilize state of the art technology
to create advanced, efficient amplifiers perfect for low impedance, 25V,
70V or 100V installations with modest power requirements.
The Ashly TRA-4150 audio controls are on the rear panel or internal.
A six-step LED meter for each channel lets you monitor all levels. All
Ashly TRA amplifiers can drive four or eight ohm loads and 70V and 100V
constant voltage lines simultaneously. Output transformers are internally
The Ashly TRA-4150 amplifier incorporates a switch-mode-power supply and
Class-D amplifier circuitry, providing an extremely power-efficient solution
for a wide variety of low wattage applications. All Ashly TRA-Series amplifiers
are convection-cooled, so there's little maintenence 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.
