Connecting The Power Cables; Troubleshooting; Specifications - Yamaha NS-B40 Bedienungsanleitung

■ Connecting the speakers and subwoofer
Connect each speaker and a subwoofer to the
appropriate speaker terminals on your amplifier by
using the cables you prepared earlier. See the
"Connection diagram" on page 3 for reference.
Make sure you connect the speakers and subwoofer
with the correct polarity—positive (+) terminals to
positive (+) terminals, and negative (–) terminals to
negative (–) terminals. If you get them crossed over,
the sound will be unnatural and lack bass.
In your AV receiver's speaker size settings, specify
small (or "S") for all of the speakers and subwoofer.
If this product doesn't work as expected, look for a possible cause below. If the issue you are experiencing is not
listed, or you cannot resolve it after reading through these instructions, disconnect the power cable and contact an
authorized Yamaha dealer or service center.
