Details
The Ashly TRA-4150 power amplifier is a 2 rack space amplifier that is perfect for low impedance, 25V, 70V or 100V installations with modest power requirements. 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.
This power amplifier has a 4-channel configuration, with power ratings of 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 transformers are internally mounted. TRA Series amplifiers also incorporate a switch-mode power supply and Class-D amplifier circuitry, providing an extremely power-efficient solution.
