TRA SERIES
The TRA Series expands on the SRA's mantra of "the
right amp for the job." These 2 rack space amplifiers
utilize our advanced, efficient amplifiers perfect for
low impedance and transformer isolated 25V, 70V or
100V installations with modest power requirements.
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. 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 trans-
formers are internally mounted.
The 150W models are 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
• Extremely low noise
• Internally mounted constant voltage transformers
• Extensive protection circuitry
