Description
SRM-252S
The SRM-252S from STAX Audio is an exclusive driver unit (amplifier) for driving STAX earspeakers with PRO-bias 5-pin connections. With a clear, simple design that excels in sound quality, SRM-252S employs carefully-selected late-model high-voltage transistors and low-noise FETs.
Class-A amplification with no coupling capacitors allows for the finest reproduction of each nuance of the music.
Although the SRM-252S includes a class-A DC amplifier in a compact case, the internal heat is effectively dissipated through the aluminium chassis, improving reliability and longevity.
The line input of SRM-252S can directly connect to the audio output of CD players, portable audio players and computers, whilst the output stage with emitter-follower configuration reinforces the driving performance and smooth sound quality.
A parallel output terminal has also been added, distributing the source signal. This means that a loudspeaker may be simultaneously connected when your source equipment has only one pair of output terminals.
