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.
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 color-coded 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.
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". Refer to the item about NAD VISO DVD RECEIVER SETUP under the ADDITIONAL DETAILS ON CONFIGURING YOUR VISO SYSTEM section to learn more about configuring your NAD VISO system.
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. MORE ON SPEAKER POSITIONING
A. Main Speakers
The three factors to adjust according to your own tastes—keeping in mind that you are the judge and the one(s) to be satisfied-are:
- The closer you place speakers to room surfaces, the greater the proportion of bass in their sound, because of the "focusing" effects of nearby surfaces on lower, longer-wavelength frequencies. Positioning the speakers near the intersection of two surfaces (wall and wall, wall and floor, or wall and ceiling) will produce more apparent bass than placing them near a single surface (a wall or floor or ceiling). The greatest apparent bass will result from placement near the intersection of three surfaces-in a room corner, near the floor or ceiling, where there will be a reinforcing effect which is somewhat uneven, like that of a megaphone.
- Distances of speakers from the wall can make a great difference in the frequency balance, sonic spaciousness, and definition in their sound, because of changes in the number, strength, and particular frequencies of secondary reflections from surfaces. The sound will generally have greater spaciousness, especially depth, if they are out at least a foot (30cm) from the nearest wall.
- Small changes in positioning may make a big difference in sound quality. Because of the varying relationships of the dimensions of a room and their relation both to where you place the speakers and where you sit, the wavelengths of sound and their interaction both with you and with the room can vary a great deal. There can be sharp increases or decreases in the relative loudness of different frequency bands, greatly amplifying or almost nullifying whole ranges. Since VISO Speakers are small and easy to position, it's easy to experiment with small, incremental changes until you are satisfied.
Ideal speaker placement: 2.1
Ideal speaker placement: 5.1
B. Surround Speakers
Begin with the knowledge of the above factors about main speakers. Then modify things as needed for your convenience and the surround effect that works best for you. If you want maximum localization and definition, you probably will want to aim the speakers toward your seating area, both
horizontally and vertically. If you prefer the surround effect to be more diffused rather than pinpointed, aiming the speakers somewhat away from your ears probably will be more satisfying. You may want even to place them to reflect their sound off the sides or rear of you room rather than have them radiate toward you. Side-wall positioning, slightly behind you as specified in our Quick Start tips, is preferable to most listeners, but rear-wall placement can work well-especially for bouncing the sound off the side walls.
C. Subwoofer
There is no argument among audiophiles that the loudest bass output from a subwoofer comes from corner placement. The natural megaphone-like flaring outward of walls from a room corner focuses low frequencies—giving them no place to go but toward you. It may be too much bass for your room or (more particularly) your favorite listening spot in the room, but unless you are seated in a "null" spot, where sound from the sub is cancelled or diminished by out-of phase reflections from elsewhere, there should be plenty of bass from corner placement.
If you are seated in such a null spot, your only real choices are generally to move either the subwoofer or your listening position until bass returns to the point that satisfies. Cranking up the level control almost certainly won't help much. But flipping the phase control 180 degrees sometimes may make a difference, especially if the null is a product of cancellations caused by interaction with low frequencies from your main speakers.
Most bass output; least even bass response
Moderate bass output; more even bass response
Lowest bass output; most even bass response
If you are in the opposite sort of situation, where direct and reflected bass waves converge in phase and produce a strong peak at your listening location, you can—if you like—deal with that both with changes in placement or in the position of your sub's level control (or, less likely but possible, the crossover frequency chosen). We say "if you like" because there is no such thing as too much bass for some listeners, and we don't want to be dogmatic. You are definitely the one who has to be pleased, unless your Significant Other chimes in to the contrary. As you go outward from the corner along one wall or another, the general consensus (with which we tend to agree) is that while 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.
Chances are things won't be so simple, so the best method for positioning a subwoofer, although a rather undignified-looking one, is to put the subwoofer in your listening chair, then play music with lots of bass through the system
something with steady low frequencies (such as organ music) or continuous test tones, not movie material. Move around the room and note where the bass sounds best; if you place the subwoofer there and yourself in your chair, you should get the same bass performance. Bear in mind that the test only works if you have your ears as high off the floor as the subwoofer will be, so don't be afraid to crawl around. A recommended starting point for the placement of this subwoofer would be in either of the front corners of the room (on either side of the main speakers).
D. About Wall-Mounting for Surround and Other Uses
The VISO speaker's rear baffle incorporates pilot holes which can easily secure speakers to Vogel VLB50 brackets.
III. ADDITIONAL DETAILS ON CONFIGURING YOUR VISO SYSTEM
A. Important:
Always turn off your electronic equipment before connecting speakers. If you don't, severe damage to equipment and/or your ears may result.
B. Selecting Speaker Wire
We recommend the following gauge (thickness) of standard two-conductor wire for the wiring distances specified; if you prefer you can use thicker (lower-gauge) wire.
Under 25 ft (<7.5m)
25 - 50 ft (7.5 - 15 m)
50 - 100 ft (15 - 30 m)
Over 100 ft (>30m)
18-gauge or 1.0 mm dia (lamp cord)
16-gauge or 1.3 mm dia (heater cord)
14-gauge or 1.6 mm dia
12-gauge or 2.0 mm dia
C. Configurations
Connect speakers identically to your amplifier or receiver on each channel—Red amp/receiver terminal to Red speaker terminal, Black to Black. This will ensure that the diaphragms of the speakers of both channels move forward and backward together ("in-phase"), rather than in opposition ("out-of-phase"). In-phase connection provides maximum clarity and bass, while out-of-phase connection results in frequency cancellations and produces thinner and less distinct sound—with less bass, vague vocal quality, and no solid center image. To help ensure the proper connection, the two separate conducting wires in a standard two-conductor speaker cable are coded in one way or another to be distinguishable from each other. (The jacket of one wire may be ribbed or marked with "+" signs, or one wire under the insulation may be a different colour from the other.) Use this wire-coding, together with the amp/receiver and speaker colour-coding, to be sure you are connecting the same wire of a given pair to a like-coded terminal at both ends of your connection. (See figures 1 & 2)
D. Tighten Terminals
Be sure all wiring terminals, are tightened firmly and securely, but be careful
not to over-tighten and damage the connectors.
E. NAD VISO DVD Receiver Setup

F. Subwoofer Level
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.
G. Subwoofer LED Indicator
When the LED is red this indicates a stand-by mode. When the subwoofer senses a program signal at its input the LED turns green. After approximately 15 to 20 minutes with no signal at its input, the subwoofer will switch to a stand-by mode and the LED turns red.
H. AC Power Switch
The Power Switch turns the NAD VISO subwoofer on and off. As the subwoofer draws only an extremely small current when idle, this may be left normally on and turned off only when you do not expect to use the subwoofer for an extended period. The Power Switch must be in the on position for normal operation.
IV. PROTECTING YOUR SPEAKERS
A. First and foremost, respect your speaker's limits. Never turn up the volume all the way to see how loud your system will play. And avoid larger-than-life playback of music or movies, especially in a large room.
B. When listening at loud volumes, do not turn the bass or treble up all the way or close thereto. This sends greatly increased, disproportionate power into the speakers and may well damage them. Loudness compensation controls, which are intended for low level listening, should be turned off at normal and loud listening levels.
C. Turning amplifiers up to their limits to produce loud sound may drive them into "clipping" and cause severe speaker damage. Often the damage is done by underpowered amplifiers, which when clipping may generate "spikes" of tremendous momentary power.
D. If you are using your speakers at loud volume, listen carefully for any sign of harsh, garbled midrange and diminishing intelligibility. If you detect any problem, turn the volume down right away.
V. CABINET CARE
Cabinets have varying materials and finishes, including high gloss "poly lacquers", vinyl, and anodized aluminum. They should be treated as you would furniture with similar finishes. Dust lightly with a soft cloth; avoiding abrasives. If necessary, wipe carefully with a cloth slightly dampened with glass cleaner to remove heavy soil. Avoid touching speaker diaphragms. In particular pushing in domes will permanently damage tweeters.
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
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.
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 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.
Thank you again for your purchase. We hope this owner's guide helps you enjoy the exceptional satisfaction that NAD VISO speaker systems have to offer. And we wish you many years of enjoyable listening!
