Speaker connection

Only speakers with low impedance (4 to 16Ω) can be
connected to the SPEAKERS CH-1/2 terminals.
Speakers of high or low impedance can be connected to the
SPEAKERS CH-3/4 terminals by setting the SYSTEM
TYPE selector.
The SPEAKERS CH-3/4 terminals are factory-set so that
the speakers with high impedance can be connected.

the SPEAKERS CH-3/4 terminals
Set the SYSTEM TYPE selector to "1" or "4."
Or, set the SYSTEM TYPE selector to "0" and use the
SRP-X500P Manager software to make setting.
When one of the settings above is made, the output from
the SPEAKERS CH-3/4 terminals becomes monaural.
Connect the (+) terminal of the speaker to the (+) (red)
SPEAKERS CH-3 terminal and connect the (–) terminal of
the speaker to the (+) (red) SPEAKERS CH-4 terminal.
