BEFORE MAKING CONNECTIONS

WIRING SPEAKER CABLE

• Be careful not to short circuit in wiring speaker cables.
• Peel off the corting of speaker cable as shown below.

to loosen.
Your speaker system must satisfy the below conditions. If it
does not, the PM-15S1's protective circuit will trip, whereby
preventing proper playback. In some cases, the amplifier and
speakers may be damaged.
• If using 1 set of speakers, total speaker impedance must be
4Ω or more.
• If using 2 sets of speakers, total speaker impedance must
be 8Ω or more.
Here following are explained two types of connections that
improve sound quality. The speakers in these explanations
have low and mid/high input jacks that support a bi-amp con-
nection. To determine whether or not your speakers support a
bi-amp connection, check in the instruction manual that came
with your speakers or contact the manufacturer.

BI-WIRING CONNECTION

Twist
conductors.
A bi-wiring connection separately connects the low and mid/
high jacks of the speaker to the amplifier using separate
speaker cables. Because separate cables are used for low
and mid/high sounds, the return current generated in the low
speaker causes little interference with the mid/high speaker.
The PM-15S1 and speakers of Connection Example 1 (pg. 5)
use a bi-wiring connection, therefore also refer to that page
for help.

COMPLETE BI-AMP CONNECTION

Proposed by Marantz, the complete bi-amp connection en-
hances the bi-wiring connection. With it, the low and mid/high
amplifiers are separate and independent of the preamplifier,
therefore interference between low and mid/high sounds is
reduced to a minimum. As a result, a wide sound environment
