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
[ ]
and using the
[ ]
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".
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
