DAISY-CHAINING SPEAKERS
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 8Ω. Since most power amplifiers are designed to provide stable
performance at a load impedance of 4 or 8Ω, 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.
PHONE PLUG WIRING
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.
