CLASS-A 50W/ch STEREO POWER AMPLIFIERA-48S

The A-48S incorporates state-of-the-art technologies to create a Class A power amplifier that delivers superb performance. Benefitting from years of ideal designs of high-performance units, the A-48S utilizes 6-parallel pull-push power MOS-FETs and boasts an output of 50 W into 8 ohms, 100 W into 4 ohms, 200 W into 2 ohms, and 400 W into 1 ohm at the same size as conventional models. The noise level has also been further reduced by 6%, while providing a damping factor of 1,000. The A-48S will bring the best out of any speaker, enabling you to enjoy unparalleled sound quality and expansiveness.
