A compact desktop HiFi system around one amplifier
TRASAM M7PLUS combines stereo amplification, digital decoding and a 3.5 mm headphone output. Connect digital sources through USB Type-C, optical or coaxial; analog sources through RCA or balanced XLR; or use Bluetooth 6.0. The TPA3255 amplifier platform then drives compatible passive speakers from the same unit.
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 part of the Class-D amplifier design, supporting stable stereo playback and controlled Class-D performance.
Digital inputs & decoding
USB supports PCM up to 24-bit/192 kHz and DSD128; optical and coaxial support up to 24-bit/192 kHz. Connect analog sources by RCA or XLR. Actual playback capability depends on the source device, software and input connection.
Speakers or 3.5 mm headphones
Drive passive speakers or connect headphones at the front. Inserting headphones stops the speaker output. The M7PLUS has no RCA line output.
Bluetooth 6.0 & listening controls
Add a compatible wireless source, adjust bass and treble, select TL5/TL6 speaker modes, and use the included remote for everyday operation.
