TRA Series specifications
Ashly’s TRA-Series expands on the SRA’s concept of “the right amp for the
job.” These 2RU amplifiers utilize our state of the art technology to create
advanced, efficient amplifiers perfect for low impedance, 25V, 70V or 100V
installations with modest power requirements. Four models available in two-
and four-channel configurations, with power ratings of 75W and 150W per
channel @ 4 ohms, 70V and 100V.
All audio controls of the TRA-Series amplifiers are on the rear panel or internal.
A six-step LED meter for each channel lets you monitor all levels. All TRA am-
plifiers can drive four or eight ohm loads and 70V and 100V constant voltage
lines simultaneously. Output transformers are internally mounted. The 150W
models are 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 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.
Features include: convection cooling, extremely low noise, an internally
switchable 120V/240V power supply (internal), extensive protection circuitry,
euroblock inputs and screw terminal outputs. Front panel features include:
mains power switch and an LED signal level meter indicating –24dB, -18dB, -
12dB, -6dB, -3dB and clip alert for each channel. Rear panel features include:
level attenuators for each channel, rear panel switches to select between
two choices of input sensitivity, remote power turn-on/off and adjustable
turn-on delay up to eight seconds.
