A compact desktop amplifier for the speakers you already own
Build a more capable desktop stereo setup around your passive speakers. The TRASAM M7BT is a compact stereo amplifier with Bluetooth 6.0 and RCA or balanced XLR analog inputs. Its Diamond Full-Balanced architecture and 2nd-generation PFFB are part of a coordinated Class-D amplification design. Use the RCA line output to feed a downstream power amplifier or powered speakers, while the speaker output drives passive bookshelf speakers.
115 W x 2 rated output
Delivers 115 W per channel rated and 150 W per channel maximum at 8 ohms, tested with a 48 V DC adapter (rated THD below 1%; maximum-output THD below 10%).
Balanced design, controlled output
Diamond Full-Balanced architecture and 2nd-generation PFFB are designed to support stable stereo playback and controlled Class-D performance.
