Congratulations on choosing PSB VisionSound Series speakers. Please take the time to read the instructions in this guide, as they will help you enjoy the full potential of your loudspeakers in any stereo or multichannel home theater application.
I. WARRANTY REGISTRATION
We recommend you take a few moments now to register your warranty, preferably on-line at psbspeakers.com/Warranty.html or via the enclosed warranty card so that we will be able to serve you better in the future.
II. UNPACKING
The packing materials of your PSB speakers are designed to protect them from damage during shipping. Retain the packaging in case the need arises to transport the speakers in the future.
III. SPEAKER PLACEMENT - MAXIMIZING YOUR ENJOYMENT
Proper loudspeaker placement is an essential ingredient to getting the best sound from your high performance stereo, multi-channel audio or home theater system. The goal is to reproduce faithfully the audio soundtrack the movie director or music producer created without calling any attention to the speakers themselves. How and where you place your loudspeakers, and where you sit relative to them will have a significant impact on the quality of the movie or music experience.
These placement effects fall into two broad categories. The first is their location around the listener and how that determines the spatial impression of the created sound field. Secondly the surfaces of the room and the systems proximity to these surfaces (the listeners proximity as well) will have a strong impact on the balance of the system.
We will deal with these in turn.
Angular position
5.1 movie soundtracks and to a lesser degree, stereo soundtracks are mixed with the intention of creating (or transporting you to) a specific sonic environment. This includes both placing sound elements at specific locations around the listener and also with creating the general impression of being in another sound space. This environment is best recreated in your home when the speakers are properly placed at the appropriate angles around your seating area.
It is best to imagine that your listening/viewing area was viewed from overhead and that your speakers will be positioned at different angles on a circle that surrounds the primary listening area. Ideally all speakers and the TV would be placed on this circle and therefore be all equidistant to the listener at the center. In reality the distances can vary by as much as 2 to 1 (farthest vs. nearest) and the sound processor's controls for level setting and time delay (if present) will satisfactorily compensate. More important are the angles of the speakers around this imaginary circle. The center speaker will of course be in the center front just above or below the television set. The left and right speakers should be about 30 degrees left and 30 degree right of center, again referring to the imaginary circle viewed from overhead the listener.
With on-wall speakers used with a flat panel (Plasma or LCD) TV it is common practice to surround the TV with speakers just a few inches separated from the set.
4
This is seldom optimum. Unless you sit quite close to the TV then the left and right speakers should be spaced farther apart than the width of the TV to get to the 30 degree left and right spacing.
With just 2 surround speakers the best location for the surrounds would be to the side rather than to the back of the listening area. They should be 90 to 100 degrees around the circle from the front (straight to the sides and just a little back of the listeners), although there is a little more leeway in where the surrounds can be placed than with the front loudspeakers.

Other hints:
Ideally, listeners will be equidistant from front right and left and center channel speakers and from rear (or side) left and right surround channels for most accurate spatial imaging. If listeners are too close to front or to rear channel speakers the image cannot come together and blend seamlessly across. With the VS300, while setting the center of the system at ear-level is ideal, the response of the system is usefully wide and some height placement latitude is permissible. The left and right speakers can be mounted at the same wall height as the television. Ideally for
comfortable viewing, the television will be seated head height or perhaps between an appropriate seated height and a standing height. Most importantly, a center channel speaker should be located centered on the TV screen - to keep center channel sound coming from the center of the screen. In the case of a wall mounted Television ( such as a Plasma TV) the system will usually be mounted just below the set. In the case of floor standing rear projection sets the center can sit on top of the unit, angled slightly downward.
Balance adjustment can compensate for some physical location difference between left and right. Time-delay adjustment within the surround sound processor (if present) can more effectively compensate for path length differences between left and right, or front and rear.
If you sit equally distant from both speakers, angling the speakers inward (“toeing them in') about 10 to 20 degrees usually produces the best convergence of high frequencies where you listen. Toe-in will also improve the consistancy of sound from seat to seat.

All VisionSound models are designed to maintain the same tonal balance when
different models are mixed in a system. Mixing a VS300, used as a center, with
VS400's as left and right is fine. The same model should be used in symmetrical
listening locations in a system – front left and front right; rear left and rear right.
Most surround sound (that is sound that comes from the surround speakers, not the
front speakers) is meant more to create greater depth and overall ambience than to
localize effects as coming from a particular spot. How much you prefer these
localized effects vs. overall sonic depth and diffusion is up to your listening
preferences. If you are listening to multi-channel music from DVD-Audio or SACD,
you may want the maximum localization of instruments. However, for most home
theater applications a diffuse sound field might be preferred. You can locate your
surround speakers to produce the effects you prefer, whether precisely pinpointed
or pleasantly diffused. In general, the farther the distance to the surround speakers
from the listener, the more diffuse the surround sound field. Diffusion can also be
created via directing the sound away from listeners, for example, your surround
speakers can be aimed towards a rear reflective surface for increased diffusion.
Proximity to Boundaries
The closer you place speakers to the boundary surfaces of your room, either to the rear or to the sides, the greater the proportion of bass in their overall sound. This is due to the enclosing, “focusing” effects of nearby surfaces on longer-wavelength (lower) frequencies. Positioning the speakers near the intersection of two surfaces (wall and wall, wall and floor, or wall and ceiling) will produce more bass than placement near a single surface. The greatest proportion of bass is delivered by placement near three intersecting surfaces–in a room corner near the floor or ceiling, where the convergence of the two walls and the floor/ceiling produces an amplifying effect that is a bit like that of a megaphone. And the least bass comes from placing a speaker away from all boundaries. Your own tastes should decide what proportion of bass response seems right in your room.
Of course, the VS300 is designed to be mounted on the wall with its included wall mounting bracket. See section VII. Response Adjustment Switches for a discussion of its special feature when wall mounted.
Where you sit in relation to your speakers obviously makes a difference too. The proportions of the particular triangle formed by your front left and front right speakers and you matter. (You may need to send more power to the more distant speaker to compensate if you get much further from one speaker than the other.) The overall distances involved also matter. As you get further from the speakers, more sound reflected from your room's surfaces (in contrast to the sound coming directly from the speakers) reaches your ears, and the original spatial relationships in a recording are changed as your room “takes over.” Sometimes the result is a mellower, more “integrated” sound. Other times, it's a more strident or annoyingly “echoey” – or other – quality. Once again, the particular dimensions and surface materials of your room play a part. And depending on what seems more realistic and/or enjoyable to your ears, you may choose to sit at a great distance or have close-up, “near-field” sound. Keep in mind that the right “toe-in,” the right speaker height, and a reasonably symmetrical distance from the speakers all tend to work together to deliver the best high-frequency definition and imaging.

Changing your own position with respect to a room's boundaries may also bring a
big effect, sometimes for a small change. Getting further from the wall behind you
may make sound more precise and localized. Getting closer may make sound more
“mellow” and integrated. Coming too close – to back wall, side wall, or (especially) a
corner – you may experience a major peak or cancellation of a certain band of
frequencies. It depends on factors we can't cover fully here but do get into on our
web site.
IV. INSTALLATION
The VS300 has a number of ways for mounting, both on wall and table-top. As shipped it will come with its on-wall bracket already attached. The two feet (included) will let you use it as a horizontal center channel either on top of a TV set or on a table in front of a television.
To mount the feet, loosen both knobs and extend the mounting bracket to create some space between the bracket and the VS300. Slot the feet onto the bracket and fasten them
with the two small Philips head (cross-head)
screws provided. Angle the system as required
Center Channel Feet
On-Wall Mounting
When wall mounting the VS300 certain tools and materials may be required as well
as a certain expertise. If wires are to be fully hidden within the walls of your house
then your best bet is to hire an experienced custom installer. (Look for a local CEDIA
certified installer in your area.) If your wires are to remain external to the walls then you can wall mount the system as long as you are handy with a few basic tools and feel confident in the process. One simple approach to hiding the wires is to put them into the walls and let them drop down to the floor level where they can exit the walls through a simple wall plate. This can be achieved with the minimum amount of wire fishing and will get the wires cleanly down to a point where they are much less visible, perhaps fully hidden by an equipment cabinet.
The following tools are useful for on-wall mounting of a VS300:
Tape Measure, Pencil, and Level Philips Screwdriver and Putty Knife Drill and Bits (smaller for lead holes and larger for cabling)
Each on-wall bracket includes two smaller holes for attachment to the wall and a larger central hole for the wire to enter the wall through. Using the guidelines below, determine the best location for your VS300's. Remove the brackets from each speaker and use them as a guide for the location of the mounting holes. The level will assure that the systems are at right angles to the TV and the horizon. Use a sufficiently strong wall mount. The only kind that we recommend are the metal expanding or “butterfly” style or the newer type were a large plastic screw pre-
and snug down the two knobs to hold the system in position.

threads into the wall and a metal screw screws into the center of it. Do not use the
simple straight split plastic inserts. Although commonly used in drywall, these
Mounting the Wall Bracket
are designed for use into brick and will NOT support the weight of a VS300.
You will see that the wall bracket has an angle between the wall mounting surface
and the two support struts. Since the bracket is reversible this allows the system
more mounting swing while reducing the required slot in the end caps. The product
comes with the right orientation for center channel use (this angle orientation allows
the feet to be attached). Note that one orientation gives more swing in one direction,
while removing and flipping the bracket gives greater swing in the opposite direction.
Between these two orientations the system can be wall mounted at any angle
required, it can even be mounted on a side wall and fired at 90 degrees down the wall
(as might be required in surround applications or if attached to a ceiling). To flip the
bracket loosen both knobs, spin them off and turn the bracket end for end. Insert the
bracket back into the end slots, being careful not to scratch the system’s finish, and reattach the knobs. You will see a rubber disc under each knob on the internal end
8
caps. This assures that the system stays put at any angle that you set it. Also note
that the mounting bracket ends have slots that allow over an inch of in/out
adjustment. This range can be used to tilt the system slightly when on wall and also
to adjust the space between the system and the wall. Most likely the installer will
hang the system on the wall with the brackets loose, connect the wires and then
push the system close to the wall and tighten the knobs.
The question of orientation may arise. That is, when mounted vertically, which side
of the system should be inside and which should be outside? Acoustically the
response is quite symmetrical so it becomes a matter of visual preference. The
system is typically mounted with the exposed cabinet edge to the inside (towards the
Plasma set) because
when angled inward the
system sets nearer the
wall.
When the VS300 is wall
mounted you may prefer
to tilt the speakers
towards ear level by
l o o s e n i n g t h e
attachment screws slightly and pulling one end or the other forward. This shouldn't be required for acoustical reasons but can help align the system with a TV that angles slightly downward, for cosmetic reasons. A slot in the wall attachment bracket is long enough for useful angle adjustment.
Table top mounting with the optional VisionSound Base Kit
You may be using the VS300’s next to a table top mounted TV. If so it may be preferable to stand them upright on the table rather than to wall mount them. We have provided for this with the optional VisionSound Base Kit. (One pair of bases per kit) Each kit includes two cast aluminum bases, a left and right spacer and replacement (sans knobs) top caps. The bases are nicely weighted and have rubber feet to keep from marring furniture.
To attach them you should first remove the two knobs and the wall bracket. Then both end caps need to come off. Although the end caps are snugly attached a firm grasp and steady pull (wiggle side to side) will remove them. Resist the temptation to pry them off with a screwdriver which would certainly mar the cabinet. Use a Philips screwdriver to remove the 4 screws from one end of either system. Note that you are turning “centers” into “lefts” and “rights” and so you need to remove the screws from one end of one system and the opposite end of the other. Add the appropriate adaptor plate (the plastic piece approximately ¾” thick) and reattach and snug the screws. The flat side of the spacer will attach to the VS300. The curved side is a mate to the aluminum base. The cast base then attaches via 3 hex key type (key included) screws. Finally, attach the new end caps. Note that you won’t be re-using the knobs so the new end caps delete the knob hole and also the unused bracket slot around back for a clean appearance.

V. CONNECTIONS
Important: Always turn off your electronic equipment before connecting speakers.
Selecting Speaker Wire
We recommend a minimum of 16 gauge speaker wire for normal length runs, and up
to 12 gauge for long runs (over 30 feet).
You may wish to audition and compare the performance of some of the specialty
audio interconnects and speaker cable available from your dealer.
When wall mounted
When wall mounting the VS300 you may wish to hide the speaker wires in the walls.
The wall mounting bracket includes a larger central hole near the input terminal cup
that allows the wires to enter the wall without being visible from the front. From the
wall bracket the wires can run back to a central equipment location or simply run
down to a junction box near the floor. Unless you are experienced in house wiring,
we recommend you engage the services of a custom installer.
Making the Connections
Be sure to connect all of the speakers in your system in an identical manner: Red or
(+) amp/receiver terminal to Red (+) speaker terminal, Black (-) to Black (-). This will
10
ensure that the diaphragms of the speakers on 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 color from the other.) Use this wire-coding, together with the amp/receiver and speaker color-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. Assure all wiring terminals are tightened firmly but be careful not to over­tighten and damage the connectors.

VII. SETUP Response Adjustment Switches
We at PSB have spent great effort to make the frequency response of your in-wall system as flat and neutral as possible. This will yield accurate and pleasurable re­creation of all manor of input materials: music, voice or movie soundtrack. Still, variations in the listening position, room acoustics and listener preferences can be accommodated using a few well chosen controls.
One of the most unique features of the VS300 is its correction for on-wall mounting. The walls of your room and the proximity of the system to these walls will have an effect on overall bass level as described above. With a bracket mounted on wall VS300 there is also a very specific phenomenon stemming from wall mounting that all on-wall speakers would share. Only the VS300 has a control to give a precise correction of this effect.
An on-wall speaker radiates sound in all directions. The sound traveling forward is the first to arrive at your ears. This “direct arrival” sound is similar to the anechoic chamber response and getting it flat was one of the criteria of designing the VS300. Sound travels backwards as well. That component of the sound will bounce off the wall behind and then carry forward to arrive at your ears about 1 millisecond behind the direct sound. The main impact of this delayed arrival is to put a significant response “hole” in the sound of your system at 500Hz, or dead center in the human voice range. This would disembody or thin out the sound of voices. A very significant amount of extra crossover network is added to the VS300, along with a switch, to compensate for this phenomenon. When the VS300 is wall mounted the switch should be set to the “on wall” position per the graphic on the rear label. DO NOT set the switch to “on wall” for any other mounting conditions such as stand mounting or table top mounting with the optional bases. Even if such mounting puts the system somewhat near to a wall it will degrade the response for any mounting conditions other than the on-wall case.
The VS400 has its own unique response adjustment control. As it is a stand mounted system and will never be mounted in contact with a wall like the VS300, there is no need for on-wall compensation. But we feel that varying room acoustics and personal preference, as well as other system factors, will give rise to a need for subtle response adjustments that balance the bass end vs. the treble end of the audible range.
To deal with this we have given the VS400 a control for “Spectral Tilt”. This is a subtle but effective 3 position control that gives the full audio spectrum a gradual uphill slope toward the treble (Spectral Tilt +) or a gradual downhill slope (Spectral Tilt-) as well as a flat or 0 position. Using the bass end as a hinge point the control tilts the response about 2dB in total (+ or-) to give a subtle yet effective means of “brightening” or “darkening” the overall balance. Although the anechoic chamber response would be flat in the Spectral Tilt 0 position, don’t be afraid to try the alternate positions on a variety of program material and leave it on the setting that sounds best to you.
Our goal is to provide listeners with completely convincing, "being there" performance. Final judgments on the quality of the sound output are of course personal. We encourage listening to the speakers with clear and familiar recordings
12
– particularly of female and male voices and acoustic instruments – to convince and satisfy listeners of the natural tonal balance, wide frequency and dynamic range, and spatial imaging delivered.
VIII. PROTECTING YOUR INVESTMENT Recommended Power
We recommend amplifiers and receivers rated from a range of 25-250 watts. For playing at consistently room-filling volume, a minimum of 100 watts is usually a good idea. Be wary of driving low-powered amplifiers to their limits as under-powering may cause “clipping” which can cause permanent speaker damage. Most people will use the VS300 in a home theater system that includes a subwoofer. This is certainly not mandatory and the VS300 will give a full and satisfying sound without a subwoofer. However, adding a subwoofer and reducing the bass power going to the VS300 will increase its total output capability considerably. In such cases where a subwoofer is used, your audio processor or receiver should be set with the appropriate channels designated as “small”.
A. For full, year-after-year enjoyment from your speakers, you should respect their
limits. Excessive volume levels can damage even the most “bullet-proof” speakers, especially over extended time periods.
B. When listening to music or movies at very loud volume, you shouldn't turn up
bass or treble all the way or close thereto. This sends tremendously increased, disproportionate power into the speakers, and may well damage them. Some loudness compensation (“Loudness”) controls, which boost both bass and treble, can also be troublesome at high volume. They are intended only for low­volume listening.
C. Finally, you should be aware that when amplifiers and receivers are pushed to
their limits to produce excessive volume levels, they are driven into “clipping” and can do severe damage – especially to tweeters. Often, the damage is done by underpowered amplifiers, which may reach their limits very soon. When such units begin to “clip” the audio waveform, they may generate high-frequency “spikes” of tremendous power. More tweeters have probably been destroyed by this phenomenon than any other. If using your speakers at loud levels, listen carefully for any sign of harsh, garbled midrange and diminishing intelligibility – and turn the volume down right away if you detect it.
NEVER TURN UP THE VOLUME ALL THE WAY TO SEE HOW LOUD YOUR SYSTEM WILL PLAY!
Cabinet Care
Cabinets are made of aluminum extrusions and precision molded plastic end caps finished in a durable paint. They should be treated as you would any fine household item with similar finishes. Dust lightly with a soft cloth; avoiding abrasive cloths, sponges or cleaners. If necessary, wipe carefully with a cloth slightly dampened with water or glass cleaner to remove heavy soil.
Grilles and Ports
A lint brush does a good job of cleaning grilles. Grilles can be taken off and vacuumed if you prefer. If need be, you can use a lint brush to clean ports. Avoid touching speaker diaphragms. Particularly, pushing in the aluminum dome of the tweeter will cause permanent damage.
13
IX. IN CASE OF PROBLEMS
A. Lower the volume if a speaker begins to sound distorted or seems to be missing
certain frequencies, to 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 a low-powered amplifier or receiver past its comfortable limits as discussed in the “Protecting Your Investment” section.
B. Isolate the problem to the electronics or the speakers and, if the speakers, to
specific speakers. Interchange the speaker wire connections on your amplifier or receiver between channels, so that the left speaker is connected to the right channel, or vice versa. If the problem shifts to the other speaker, the problem is not in the speaker but in the electronics.
C. Another component – or, very often, a cable or connection problem between
components – may be at fault. If the problem stays in the same speaker, irrespective of the channel to which it's connected and after changing the connecting wire the speaker itself probably needs service.
D. See your dealer if you require service. PSB dealers are equipped to handle
almost all problems. If you have moved since your purchase, the nearest authorized PSB dealer should be able to help you. You may locate your nearest PSB authorized dealer on-line at www.psbspeakers.com.
