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 are 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 amplifiers 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 for a wide variety of low wattage applications..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.
