BEFORE MAKING CONNECTIONS
Your speaker system must satisfy the below conditions. If it
does not, the PM7001’s protective circuit will active, 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.
WIRING SPEAKER CABLE
• Be careful not to short circuit in wiring speaker cables.
• Peel off the corting of speaker cable as shown below.
• Wiring with speaker cable.

Here following is explained BI-WIRING connection that im-
prove sound quality. The speakers in this explanation have
low and mid/high input jacks that support a BI-WIRING con-
nection. To determine whether or not your speakers support a
BI-WIRING connection, check in the instruction manual that
came with your speakers or contact the manufacturer.
BI-WIRING CONNECTION
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 kick back current in the low speaker
causes little interference with the mid/high speaker. The
PM7001 and speakers of Connection Example 1 (pg. 5) use a
bi-wiring connection, therefore also refer to that page for help.
