Troubleshootin g
If any specific problem should persist, contact your Yamaha dealer.
Symptom Possible causes Possible solution
No sound. The cable is not connected properly.
Connect the speakON cable to the [INPUT/
PARALLEL] jack correctly. When using in the
Passive mode, make sure to connect the 1+/
1– contacts of the speakON cable to the
amplifier outputs.
Sound is interrupted sud-
denly.
The speaker units are damaged.
If no sound although the connection and sig-
nal level are appropriate, there is a possibility
of malfunction of the speaker units. Contact
your Yamaha dealer.
The amplifier shuts down.
When connecting the speakers in parallel,
the total impedance of the speakers is less
than the minimum load impedance of the
amplifier.
(For example, when more than three eight-
ohm speakers are connected in parallel to
an amplifier having a minimum load imped-
ance of four ohms.)
Lower the number of speakers connected in
parallel, or use an amplifier which can drive
with the total impedance of the speakers, in
order to not be less than the minimum load
impedance of the amplifier.
The protection system of the amplifier has
been enabled because the input volume is
excessive.
Wait until the amplifier cools down. Before
using it again, lower the input volume.
No high-frequency sound.
The HF protection system has been
enabled. Refer to the “Protection Circuit” NOTICE on
page 3.
When using in the Bi-amp mode, the signals
are sent only to the 1+/1– contacts of the
[INPUT/PARALLEL] jack.
When using in Bi-amp mode, send the correct
signals to the 1+/1– and 2+/2– contacts of the
[INPUT/PARALLEL] jack.
(1+/1–: LF, 2+/2–: HF)
Sound is distorted. Input volume is excessive.
Lower the volume of the input device so that
the limit indicator of the amplifier lights only
occasionally.
