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
any problems arising out of the use of these circuits or for any infringement of third party patent and other right due to same.
