VI. IN CASE OF PROBLEMS
A.
If a speaker begins to sound distorted, or seems to be missing certain
frequencies, check first to see whether playing at somewhat lower volume
seems to clear up the problem. It can be especially important to turn down
the volume right away if you have pushed an amplifier or receiver past its
comfortable limits.
B.
Determine if the problem is the speakers, the electronics, or the wire
connections. If a problem on one speaker doesn't go away, interchange
the speaker wire connections on your amplifier or receiver, so that the left
speaker is connected to the right channel, and vice versa. If the problem
shifts to the other speaker, the problem is not in the speaker. (Another
component-or, very often, a cable or connection problem between
components-may be at fault.) If the problem stays in the same speaker,
swap the speaker cables next. If the problem remains in the same
speaker, irrespective of the channel to which it's connected and the
connecting wire used, the speaker itself probably needs service.
C.
See your dealer if you require service. NAD dealers are equipped to
handle almost all problems. If you have moved since your purchase, the
nearest authorized NAD dealer should be able to help you. If the problem
is not resolved, please contact us, providing the Model name, Serial
Number, date of purchase, dealer name, and a full description of the
problem.

VII. IN CASE OF PROBLEMS WITH YOUR SUBWOOFER
Symptom
Action
No sound/power
indicator not lit
Ensure the main power switch is toggled to the “Power” position.
This switch is located at the back of the subwoofer.
Ensure the power cord is connected to the subwoofer and plugged
into a live AC outlet.
Check the main fuse located in the power cord socket and replace
as required. If the new fuse also blows, the subwoofer amplifier
requires service.
The VISO S10 subwoofer utilizes signal sensing auto on/off circuitry.
If no signal is sent to the subwoofer, it will not power up and the front
panel power indicator will remain red. When using the subwoofer
output of the VISO receiver, no signal may be immediately present in
this output. The subwoofer will only power up when a signal appears
at the subwoofer input.
If the signal cable connection is poor or has been severed, the
subwoofer will not power up. Swap cables to determine if this is the
source of the problem.
To ensure the problem is not associated with the subwoofer, rapidly
No sound/power
indicator remains red
