Connecting the SpeakersCONNECTION EXAMPLEThe illustration below shows audio connections for a standard setup using two speaker systems.DAISY-CHAINING SPEAKERSSince the speaker systems in this series are equipped with two input terminals that are internally connected in parallel, it ispossible “daisy-chain” speakers by connecting the output from the power amplifier to one phone jack, and a second speakersystem to the other.All speaker models in this series have a nominal impedance of 8Ω. Since most power amplifiers are designed to provide stableperformance at a load impedance of 4 or 8Ω, Yamaha recommends that no more than two 8Ω speaker systems be daisy-chainedtogether. This will allow the amplifier to operate properly and avoid overheating.CAUTION!For the four models, S10e, S12e, S15e and S12Me, use theTS-30, TS-40, TS-80, or TS-90 speaker stand by UltimateSupport System, Inc. sold separately.When using speaker stands, observe the following precau-tions to prevent the speaker stands from falling over or thespeaker system being dropped.• Use the speaker stands with their legs fully opened.• Do not place more than one speaker on the same speakerstand.• Tighten fastening screws securely.• Remove the speakers from the stands before moving thestands or adjusting their height.• Implement measures to prevent the speaker stands fromfalling over.• Use the stand at no higher than 150 cm for all speakermodels.• The top tube of the TS-30 and TS-40 speaker stands hasa diameter of 1-1/2", but is tapered to 1-3/8" at the top tofit in the mounting holes on the four models named. Ifyou should remove the top tube from a stand, be sure toinsert it with the narrow end up when reassembling.
