Once you have held the SA-36A Pro in your hand, you will know quality craftsmanship and high-end components go into the making of this amp. At its heart lies the TDA7492 amp chip. The high efficiency of this component provides smooth detail in the mids and highs and solid, powerful bass. It is fully protected against faults with short-circuit and thermal protection as well as over-voltage, under-voltage, and DC protection.
Use the SMSL SA-36A Pro where space is limited and great quality music is desired. At 3-1/2" x 5" this amp will fit nearly any setting. Operation is quite straight forward with a small power button and large analog volume knob on the front panel.

A 15V 4A DC power supply is included and provides ample current so this amplifier functions at peak performance.
