ASHLY TRA-2075 Convection-Cool Power Amplifier w/ Xfmr Iso 2 x 75W @ 4/8 Ohm, 25V, 70V

Product Overview

The Ashly TRA-2075 is a 2-channel convection-cooled transformer-isolated power amplifier delivering 75W per channel at 4 ohms, 40W at 8 ohms, and 75W per channel across 25V, 70V, and 100V constant-voltage outputs. As part of the Ashly TRA convection-cooled amplifier series, the TRA-2075 is the lower-power 2-channel model designed for commercial paging and background music installations with modest zone power requirements, where transformer-isolated constant-voltage distribution and completely fanless operation are required in quiet environments.

Product Description

The Ashly TRA-2075 provides 2-channel output with internally mounted output transformers for 25V, 70V, and 100V constant-voltage distribution. Both channels can drive 4 or 8 ohm low-impedance loads simultaneously with the constant-voltage outputs. The switch-mode power supply combined with Class-D circuitry delivers efficient operation in a 2U convection-cooled chassis. Without fans, the TRA-2075 requires minimal maintenance after installation and operates in silence—appropriate for boardrooms, courtrooms, conference rooms, and other permanently installed environments where acoustic performance includes the amplifier room. A 6-step LED level meter on each channel provides visual signal monitoring. All audio controls are located on the rear panel for a clean front panel appearance. Rear-panel controls include per-channel level attenuators, a gain switch (+36 dB or +26 dB input sensitivity), selectable input sensitivity, and Euroblock input/output connectors. Remote standby control and an adjustable turn-on delay (up to 8 seconds) allow integration with room control systems and prevent speaker damage from power-up transients. Extensive protection circuitry covers output overcurrent, DC output faults, main supply rail overvoltage, in-rush limiting, and a mains fuse. The TRA-2075 is certified to TUV, CE, FCC, and RoHS standards and carries a 5-year warranty.

Frequently Asked Questions

How does the TRA-2075 differ from the TRA-2150?

The TRA-2075 delivers 75W per channel versus 150W per channel for the TRA-2150. Both provide the same transformer-isolated 25V, 70V, and 100V outputs, the same convection-cooled fanless design, and the same feature set. The TRA-2075 is appropriate for smaller distributed audio zones with moderate power requirements.

Does the TRA-2075 include built-in output transformers for 70V distribution?

Yes. The TRA-2075 has internally mounted output transformers providing transformer-isolated 25V, 70V, and 100V constant-voltage outputs without any external transformer hardware.

Is the TRA-2075 suitable for quiet boardroom and conference room installations?

Yes. The TRA-2075 is fully convection-cooled with no fans, producing no fan noise in permanently installed commercial spaces.

Can the TRA-2075 drive 4-ohm and 70V speakers simultaneously?

Yes. The TRA-2075 can drive 4 or 8 ohm low-impedance loads and constant-voltage lines simultaneously, supporting mixed speaker installations on the same amplifier.

What room control integration does the TRA-2075 support?

The TRA-2075 provides a remote standby control for contact-closure or trigger-based power management from standard commercial room control systems.
