∗ The input signal enters the pre-amplifier with attenuation controlled with DC at Pin 14 and then it is amplified

by the approximately 30 dB (fixed) power amplifier.

∗ The state of Pin 2 can be used to select between stereo mode and monaural BTL mode.

The pre-power 1 and pre-power 2 output are positive phase output when Pin 2 is GND. Pre-power 2 is

inverse output of pre-power 1 output when Pin 2 is open.

Application circuits shown are typical examples illustrating the operation of the devices. Sony cannot assume responsibility for
