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 Owners Manual at www.nadelectronics.com I. QUICK START A. Attach the supplied adhesive backed bumpers near the corners of the LR5s and C20s 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 positionslightly 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 subwoofers phase switch to 0 and volume switch to 0dB. Flip the Power Switch to the on position.
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 [? on the remote control select Center Channel speaker ] button and using the [< select -3dB. If you're using an NAD VISO TWO DVD ] button Receiver, configure the following settings via the Audio Setup Menuin 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 accordinglyit 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 [? buttons on your receivers remote control to adjust ] or [> ] 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 5

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.

Symptom No sound/power indicator not lit Action 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 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.
