BI-WIRING CONNECTION

Abi-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.

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.

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 can be reproduced. Connection Example 3 (pg. 7) connects two PM-15S1s by FCBS in a complete bi-amp connection, therefore also refer to that page for help.
