取扱説明書
Thank you for choosing the Yamaha S15/S15W speaker
system. The S15/S15W is a compact two-way bass-reflex
speaker system equipped with a 12 cm (5") woofer and a 2.5
cm (1") tweeter. From powerful bass to delicate high-frequency sounds, the system provides well-balanced high
quality sound reproduction over the entire frequency range.
To obtain maximum performance from your Yamaha
speaker system we recommend that you read this operation
manual thoroughly.
PRECAUTIONS
● Be sure to turn the amplifier power OFF before attempting
to connect the speakers.
● To avoid distortion and possible damage to the speaker
units, never drive the speakers with more than their maximum rated power.
● The nominal impedance of the speaker system is 6 Ω.
Since the output characteristics of the amplifier vary depending on the load impedance, the load impedance has a
tolerance. If you are expanding the speaker system, be sure
to observe the range of specified amplifier load impedance.
● When two or more speakers are driven by separate power
amplifier channels, be sure that all speakers are connected in
phase to avoid a loss in output level and sound quality.
CONNECTION
Connect the speaker cables from the input terminals on the rear
of the system. The red input terminal on the system should be
connected to the output terminal (+) on the power amplifier, and
the black output terminal should be connected to the output (–).
Incorrect polarity will impair bass sounds, producing an unnatural sound.

ABOUT THE PROTECTION CIRCUIT
The tweeter in this speaker system has an internal protection
circuit that shuts off the tweeter when an excessive
inputsignal is applied.
If the tweeter emits no sound (i.e., the sound lacks high frequency content), reduce the volume level of the amplifier immediately. The sound will return automatically in several
seconds.
