Here are few specs:
The S-3 Signature II is a single ended Dual-Mono solid state stereo integrated amplifier features the proprietary Mirror-Amp™ electronic design producing a super-linear signal, thus virtually eliminating distortion.
The power supply is handled by three E.I. custom made transformers, of which two dedicated to the audio signal path, while a smaller galvanically isolated powering all the accessory functions such as the motorized volume control, the relays, the power ON led light and even the micro-chip used for electro-mechanical functions.
The S-3 SIGNATURE II does not have active or passive filters on the audio signal path. Four thermal switches strategically positioned shut off temporarily the amplifier reaches a too high internal temperature till cooling down. To ensure large power capability the S-3 SIGNATURE II features two precision low noise fans separately powered to keep the unit cooler and more stable.
The fan's bearings are low noise kind increasing the speed proportionally to limit the unnecessary noise.
The amplifier chassis is made of Steel to minimize RFI and EMI interference.
The S.3 Signature II features a high quality built in headphone amplifier having a 6,3mm jack input.
