Product Description

SL-A32 provide high-performance, thermally efficient amplifier solutions. it delivers 2x15W+15W  into 8Ω loads. it is three channels amplifier ,one channel  is L and R channel combined.with good sound.

it operate from a single 8V to 18V supply and provide a high 67dB PSRR, eliminating the need for a regulated power supply. They offer up to 90% efficiency from a 12V supply.
Both devices feature eight-digitally-controlled gain settings.

  • Output Power: Maximum 2*15W+15W at RL=8Ω,VCC=18V

  • Power efficiency is up to 90%

  • Low Working Voltage Down To 8V, High Working Voltage up To 18V

  • Thermal Protection function

  • Output Pin Short-Circuit Protection
