By connecting a signal processor such as an
equalizer or limiter between the preamplifier section
(PRE AMP OUT) and the power amplifier section
(PWR AMP IN) of the A-700 series, signals can be
tailored for desired sound output.
Note
Inserting an RCA plug into the PWR AMP IN
terminal disconnects the internal power amplifier
section from the preamplifier section.
