Overview: The STK400-030 is a 3-channel AF power amplifier IC  supporting multichannel speakers. One package includes  20W×3ch for Lch, Rch and Cch. It is pin compatible with  both 3-channel output devices (STK400-*00 series) and 2-  channel output devices (STK401-*00 series). The output  load impedance is 6/3Ω. Features: New series combining 3-channel output devices  (STK400-*00 series) and 2-channel output devices  (STK401-*00 series) with the same pin compatibility.  Output load impedance is 6/3Ω.  Pin assignment is grouped into individual blocks of  inputs, outputs and supply lines, minimizing the adverse  effects of pattern layout on operating characteristics. Minimum number of external components required. Circuit Diagram: 20W+20W+20W AF Power Amplifier
