Ashley TRA-4075 TRA Series Amplifiers
Ashly’s TRA-Series expands on the SRA’s concept of “the right amp for the job.” As with the SRA-Series, these 2RU amplifiers utilize our state of the art technology and advanced engineering to produce highly efficient amplifiers that are convection cooled, so there’s little maintenance after the installation and no annoying fan noise. The main difference between SRA and TRA is that the TRA-Series amplifiers move level controls to the back, give you expanded metering, and provide low impedance and transformer coupled 70V and 100V outputs simultaneously (output transformers are internally mounted).
TRA-Series amplifiers incorporate a switch-mode-power supply and Class-D amplifier circuitry, providing an extremely power-efficient solution. The TRA-Series amplifiers include four models available in two- and four-channel configurations, with power ratings of 75W and 150W per channel @ 4 ohms, 70V and 100V.
