Since the speaker systems in this series are equipped with two input terminals that are internally connected in parallel, it is

possible “daisy-chain” speakers by connecting the output from the power amplifier to one phone jack, and a second speaker

system to the other.

All speaker models in this series have a nominal impedance of 8

Ω. Since most power amplifiers are designed to provide stable

performance at a load impedance of 4 or 8

Ω, Yamaha recommends that no more than two 8Ω speaker systems be daisy-chained

together. This will allow the amplifier to operate properly and avoid overheating.

The standard input terminals for this unit are 1/4" phone jacks. Connect the speaker leads as shown in this diagram.

Caution: Use only unshielded speaker cable with stranded conductors to connect speakers to the speaker terminals on a power

amplifier. The use of audio cable not rated as sufficient for the amplifier’s maximum output level can create a potential fire

hazard.
