Thank you for your purchase. The NAD VISO speakers are designed to deliver
high performance in many uses, and we hope they add much enjoyment to your
listening life.
For detailed information on speaker positioning, NAD VISO DVD Receiver
set-up and complete system configuration please refer to the
comprehensive VISO TWENTY/VISO THIRTY Owner’s Manual at
www.nadelectronics.com
I. QUICK START
A. Attach the supplied adhesive backed bumpers near the corners of the LR5’s
and C20’s bottom surface to protect the finish of speakers and furnishings.
B. Position LR5 speakers as symmetrically as possible, at a comfortable
distance from your seating position—slightly closer to each other than they
are to you. Position the C20 center channel directly above or underneath
your TV screen. (Keep its front as much in line as possible with the front of
the picture.)

C. Using standard lamp “zip cord” (18 gauge/1.0mm dia) wire or better, connect
the Red (positive) binding post of each speaker to the Red terminal of your
signal source on the channel. Similarly, connect Black (ground) on each
speaker to Black on that channel's signal source. (If the output of the signal
source is via a proprietary cable with a jack at one end, connect the colorcoded wires at the other end of the cable to the speaker's similarly-coded
posts.) Be sure to follow color-coding to make sure that your speakers
are “in phase” for smoothest sound with deepest bass.
D. The loudest bass output from a subwoofer will come from corner placement.
As you position the subwoofer outward from the corner along one wall or
another, bass output diminishes somewhat, it also becomes more uniform
throughout the room, with fewer of the “standing waves” that produce peaks
and nulls at various points. Turn off all other components, and follow one of
the connection diagrams. Connect the supplied power cord to the AC power
socket, then plug the subwoofer into an active AC outlet. The same receptacle
as the rest of your audio/video system or another on the same electrical
circuit should be used to avoid ground hum. Set the subwoofer’s phase switch
to 0° and volume switch to 0dB. Flip the Power Switch to the on position.
4
F. Find a comfortable volume setting and play a bass-rich program source.
Slowly adjust the [SUB] level button on the remote control of your NAD VISO
DVD Receiver until the subwoofer contributes a natural level of low frequency
sound. Now, please read the rest of this guide and fine-tune your installation
accordingly—it will be time well spent!
II. IMPORTANT INFORMATION ON SUBWOOFER LEVEL CALIBRATION
When calibrated, the bass reproduced by the subwoofer is on the same
relative level as the signal reproduced by the full range speakers.
Always start your subwoofer volume adjustments from the calibrated
subwoofer reference level. The calibrated subwoofer reference level is
achieved when the volume switch on the VISO subwoofer is set to the 0dB
position (factory default) and subwoofer level is set to 0dB on the VISO
receiver. Use the [?
] or [>
] buttons on your receiver’s remote control to adjust
the subwoofer level.
Another setting that achieves the calibrated subwoofer reference level is the
+10dB position on the VISO subwoofer and the -10dB subwoofer level on the
VISO receiver.
With the subwoofer volume set to 0dB, if by gradually increasing bass output
at the VISO receiver a point is reached at which the subwoofer starts audibly
to clip and/or the bass output from the subwoofer is insufficient, this indicates
that the volume on the subwoofer is set too low. In such a case, turn down the
subwoofer level on the VISO receiver to -10dB and set the volume switch on
the subwoofer to the +10dB position. Then by adjusting again the subwoofer
level on the VISO receiver, set the desired bass level.
III. TROUBLESHOOTING
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

E. Turn ON your NAD VISO DVD Receiver. If you're using an NAD VISO FIVE
DVD Receiver, ensure that the settings for “Front”, “Centre” and “Surround”
speakers are all set to “Small” via the “Speaker Settings” section of the Audio
Setup menu. Return to Audio Setup menu and select Channel Levels. By
pressing the [?
] button on the remote control select Center Channel speaker
and using the [<
] button select -3dB. If you're using an NAD VISO TWO DVD
Receiver, configure the following settings via the Audio Setup Menu—in
“Listening Mode” set the mode to “DVS Reference” and in “Speaker Settings”
menu set “Front” to “Small”.
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.
IV. TROUBLESHOOTING—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.
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.
No sound/power
indicator remains red
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
disconnect and connect the subwoofer input signal. If the subwoofer
power indicator color changes to green, the VISO receiver may not
be sending a signal to the subwoofer. Ensure the VISO receiver is
correctly configured to provide signal at the subwoofer output.
Sounds distorted
Lower volume if the subwoofer begins to sound distorted to
determine if playback at a lower level solves the problem. If a slight
reduction in level solves the problem, were you being realistic in your
subwoofer level setting? If the distorted sound remains at a low
level, the woofer may be damaged.
Hum
Hum is usually caused by using an inferior, damaged, exceptionally
long signal cable or cables routed near high current
6
wiring/appliances. Replace/shorten the cable connecting the
subwoofer to the VISO receiver. Cable runs of longer than 20 feet
may require the use of a line driver (not available from PSB).
Setting the volume switch of the subwoofer to 0dB and increasing the
volume control of the VISO receiver subwoofer output can sometimes
reduce hum to an acceptable level.
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.
