AMP 100V IN: standby power amplifier 100V input interface (note positive and
negative);
SIGANL OUT: signal output interface, access to the standby amplifier input port.
Note: When using the standby power amplifier, you need adjust its volume to the appropriate
position to ensure the amplifier is 100V output.
