SMSL DA-8S Amplifier Class D Infineon MA12070 NJW1194 Balanced Bluetooth 5.0 2x80W 4 Ohm

The SMSL DA-8s is a compact and affordable yet high performance balanced Class D amplifier, delivering a comfortable 2x80W power output at 4Ω with a high efficiency of over 92%. These impressive capabilities come from an Infineon MA12070 amplifier module, which provides excellent sound reproduction while limiting power consumption. The volume control is entrusted to an NJW1194 chip, allowing precise volume adjustment without adding distortion. The SDB mode of the unit offers the possibility to adjust the bass and treble levels over a range of -10dB to +10dB. On the connection side, the DA-8s is simple and efficient. The rear panel of the amplifier displays a balanced XLR input and an unbalanced RCA input, as well as speaker output terminals. A small particularity, the SMSL amplifier has Bluetooth 5.0 connectivity supporting the aptX and thus offering the possibility to play music directly from your smartphone or tablet. The entire DA-8s circuitry benefits from a careful design, incorporating quality components such as Siemens coupling capacitors or Nichicon filter capacitors.

Remote Control:
Install 2 x AAA batteries as instructed. When using the remote control, point it toward the remote control signal receiver on the main unit from a distance of 5 m (16 ft) or less. Do not place obstructions between the main unit and the remote control. The remote control might not work if the remote control signal receiver on the unit is exposed to direct sunlight or bright light. If this occurs, try moving the unit. Beware that the use of this remote control could cause the unintentional operation of other devices that can be controlled by infra.

Note: Please pay attention to the polarity when connecting the speakers, it must follow the mark on the unit, to avoid any effect on the sound quality.
