SAFETY PRECUATIONS

WARNING: to prevent fire or shock hazard, do not expose this unit to rain or moisture. Care should be taken to
prevent objects or liquid from entering the enclosure. Never handle the power cord with wet hands.

The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user of the presence of
uninsulated “dangerous voltage” within the product’s enclosure that may constitute a risk of electric shock to you.

The exclamation point within an equilateral triangle is intended to alert the user of the presence of important
operating and maintenance (servicing) instructions in the literature accompanying the unit.

Caution: To prevent the risk of electric shock, do not remove cover. No user-serviceable parts inside. Refer

servicing to qualified service personnel.

If an outdoor antenna is connected to the antenna input, be sure it is grounded to provide some protection against
voltage surges and built up static charges. Keep the outdoor antenna away from power lines.

Unplug the processor from the AC outlet when plugging in or unplugging cables, when left unused for an
extended period of time, moving the processor, or when you suspect lightning in your area.

Prevent damage to the power cord. Do not bend, pull, place objects on, alter, etc. Replace the power cord if it
becomes damaged. Always grasp the plug on the power cord when plugging in or unplugging the processor from
the AC outlet.

Your system may produce sound levels capable of causing permanent hearing loss. Do not operate for extended
periods of time at high volume levels.

Make sure the processor is placed on a level surface.

Protect the processor from impact. (Do not drop it!!!)

Do not climb on top of the processor or place heavy objects on its top cover.

The processor is equipped with raised feet to provide ventilation, reduce acoustic feedback, and provide
protection against scratching the surface the unit is resting on. We advise against removing or altering feet.

Do not stack anything on top of the processor (processor, source, etc.) Leave a minimum of 3” clearance from the
top of the processor to the next shelf (or component).

The processor should be located away from heat sources such as heaters or amplifiers.

Do not perform any internal modifications to the processor.

Always connect the processor’s power cord to an unswitched AC outlet for normal operation.

If young children are present, adult supervision should be provided until the children are capable of following all
rules for safe operation.

Do not plug the processor’s power cord into an outlet with an unreasonable number of other devices. Be careful if
using extension cords and ensure the total power used by all devices does not exceed the power rating
(watts/amperes) of the extension cord. Excessive loads may cause the insulation on the cord to heat and possibly
melt.

Mistaking CONTROL OUTPUT or IR INPUT connectors for audio/video inputs or outputs may damage your
processor or other components.

Damage can occur to your speakers if the power rating of each individual driver is exceeded by the amplifiers
connected to your processor. Ensure that all the drivers in your system are capable of handling not only the
average power being delivered by the amplifiers, but also the peak power that is likely to be generated during
strong passages. If you are unsure of your speaker's power rating, contact the speaker manufacturer or the dealer
where you purchased them.

The processor should be serviced by qualified personnel when:

A.

The processor is not functioning properly.

B. Objects have entered the chassis.
C. The processor was exposed to rain or other type of moisture.

D. The processor was dropped, or the chassis is damaged.

THE BASICS

The following is intended to familiarize users with common terms and applications of Home Theater equipment.

Sources - your processor can directly provide audio from its built-in AM/FM tuner. It can also provide limited

video from its on-screen menu system. Typically you will want to connect a number of additional sources (VCR,
DVD player, etc.) to your processor. Your processor is designed to accommodate a wide range of audio and
video signals.

The following table lists the most popular home theater media and how the audio information is stored.

Source Media Analog PCM Dolby Digital DTS

Video Cassette X
Laser disc (LD) X X X X

Compact Disc (CD)
Digital Versatile Disc (DVD)
Satellite Broadcast
Digital Audio Tape (DAT) X X X X

Analog vs. Digital Audio - This refers to the method used to place audio information on the source material and

how they are delivered to your processor from the source. Analog signals exactly represent the sound you will
hear through a continuously varying voltage. Audio and video cassettes are analog recordings and are normally
delivered to your processor over a pair of coaxial audio cables.

Digital signals closely approximate the original audio signals with a set of numbers referred to as a bitstream. CDs
and DVDs are sources of digital audio and are normally connected to your processor through a coaxial or optical
digital cable. There are several different bitstream formats available. The simplest format is called Pulse Code
Modulation (PCM). In PCM, the bitstream directly represents the original 2-channel audio. In Dolby Digital and
DTS (see “Surround Formats” below) bitstreams are modified using a process called compression to squeeze
more information into limited space. DTS squeezes 5.1 channels into the space normally required for two
uncompressed channels, while Dolby Digital squeezes 5.1 channels into about ¼ the space required for two
channels. Your processor automatically detects the bitstream currently being provided from the source and
performs the required decompression and surround processing. If no digital signal is present your processor will
automatically switch to analog processing.

All sounds that you hear from your speakers are analog. Digital signals are automatically converted to analog by
your processor before being output to your the speakers.

If analog signals exactly represent the audio, while digital signals only approximate it, why would I want to
use digital?

All analog sources add some amount of noise and distortion to the audio signal. Additional noise can be
picked up through the cables from the source to your processor. It is impossible for the processor to tell
the difference between the desired signal and the added noise and distortion, so it reproduces both of
them. The result is increased background noise and decreased dynamic range and fidelity. Digital signals
are virtually immune to noise and distortion. The processor can, therefore, reproduce the signal with the
greatest possible fidelity. We recommend you use digital signals wherever possible. Also Dolby Digital
and DTS (see “Surround Formats” below) work only

Audio and Surround Formats - Your source material will be in one of seven possible formats described below.

Monaural (Mono) - This is the oldest format available. It contains a single, full range audio channel.

Modern recordings are seldom made in this format, but most older movies and music are available only in
this format. You may get mono from any source - digital or analog. Sound will normally come from the

with digital signals.

5

seven speaker channels, but your processor can produce mono in one to seven channels (see “Audio
Modes under Operation”). Since all modern sources are stereo, the mono information is usually
replicated from both the left and right channels.

Stereo - Stereo contains two discrete, front left and right full range audio channels. This is the most

common format for music and is also used on many movies. You may get stereo from any source - digital
or analog. Sound will normally come from the seven speaker channels, but your processor can produce
stereo in one (mono) to seven channels (see “Audio Modes under Operation”).

Dolby Pro Logic - Dolby Pro Logic is a refinement of Dolby Surround, which was the earliest form of true

surround processing. Like Stereo, Dolby Surround contains two discrete, full range audio channels. In
addition, a monaural, limited range surround channel is encoded on the two stereo channels in a process
called matrixing. The surround channel information is encoded in positive polarity on the left channel and
in negative polarity on the right channel. The Dolby Processor can detect this encoding (left minus right)
and send that information to the surround channels. Dolby Pro Logic adds additional processing to
produce a full range center channel by extracting the mono information from the left and right channel.
This is the most common format for all but the most recent movies. Music sources are occasionally
encoded in Dolby Surround. However, many people prefer to use Pro Logic processing on all of their
stereo sources. The center channel extraction process often yields improved stereo imaging, especially
when you are sitting away from the “sweet spot” at center of the listening area. The surround channel
processing often lends a pleasing ambiance even to material that is not encoded in Dolby Surround.
Dolby Pro Logic is fully compatible with stereo and you may get it from any source - digital or analog.
Sound will normally come from all seven speakers in your system, but your processor can produce sound
in one (mono) to seven channels (see “Audio Modes under Operation”).

Dolby Digital - Dolby Digital contains up to five discrete, full range audio channels plus an additional Low

Frequency Effects (LFE) channel. The LFE channel contains only low frequency information for enhanced
sound effects in movies. This combination of five discrete channels plus a LFE channel is often referred
to as 5.1 channels. Dolby Digital is a digital format only. It must be delivered to your processor over a
coaxial or optical digital cable. As of the writing of this manual, Dolby Digital is commercially available on
DVD and Satellite (Also see Dolby Digital RF below). It is also possible to create your own Dolby Digital
CDs and DATs if you have the recording equipment. You can’t directly record Dolby Digital onto mini disc
or digital compact cassette since these devices add their own compression, which is incompatible with
the Dolby Digital compression. Not all Dolby Digital recordings will include all five channels, and, in fact, it
is common on DVDs to have two channel Dolby Digital with or without Pro Logic processing. Sound will
normally come from all seven speakers in your system, but your processor can produce sound in one
(mono) to seven channels (see “Audio Modes under Operation”).

Dolby Digital RF - Dolby Digital RF is identical to normal Dolby Digital except that it uses a special RF

encoding scheme to put the bitstream on Laser discs without replacing the normal stereo (or Dolby
Surround) PCM bitstream that is normally available from laser disc. In order to use Dolby Digital RF laser
discs you must have a B&K DT-1 RF demodulator or similar product from another manufacturer. For best
results with your processors Plug and Play capability we recommend the B&K DT-1.

Dolby Digital Surround EX - Dolby Digital Surround EX is a new movie sound track that greatly

enhances the sense of spatial and positioning of the surround channel sound. This system was
developed jointly by Lucasfilm THX and Dolby Laboratories, using Lucas film’s idea of improving spatial
expression and achieving a 360-degree sound positioning with Dolby Laboratories’ matrix encoding
technology. The surround back channel is matrix-encoded and inserted into both Dolby Digital SL
(surround left) and Dolby Digital SR (surround right) channels. Upon playback, the signals may be
decoded by a high precision digital matrix decoder within the Dolby Digital decoder into SL, SR and SB
channels.

DTS (Digital Theater Systems) - DTS is similar to Dolby Digital in that it provides 5.1 discrete audio

channels. However, it uses more digital data to encode the information and may provide greater fidelity
than Dolby Digital. DTS is a digital format only. It must be delivered to your processor over a coaxial or
optical digital cable. No RF demodulator is required for DTS laser discs since the DTS bitstream replaces
the normal PCM bitstream. Like Dolby Digital, you can create your own DTS DATs or CDs but not mini
disc or digital compact cassette. As with Dolby Digital, sound will normally come from all seven speakers

6

in your system, but your processor can produce sound in one (mono) to seven channels (see “Audio
Modes under Operation”).

DVD Audio (also referred to as MLP) - Meridian Lossless Packing (MLP) is a lossless coding system for

high-quality linear PCM audio. For DVD-Audio MLP performs lossless compression of up to 6 channels of
up to 24-bit material sampled at rates between 44.1kHz and 192kHz. Lossless coding does not alter the
final signal, it ‘packs’ the audio data into a smaller rate and space. Currently, DVD Audio can only be
delivered to your processor via the 6 coaxial digital inputs. The coax digital inputs may be configured
internally for use as an analog 5.1 input. Sound will normally come from all seven speakers in your
system, but your processor can produce sound in one (mono) to seven channels (see “Audio Modes
under Operation”).

Home THX Cinema Processing - THX is an exclusive set of standards and technologies established by

the world-renowned film production company, Lucasfilm Ltd. THX grew from George Lucas’ personal
desire to make your experience of the film soundtrack, in both movie and in your home theater, as faithful
as possible to whate

ver the director intended. Currently, the Reference 20 Plus does not support Home THX

13258 0303

Bass Management - Dolby Digital and DTS formats contain up to 5 full range channels plus LFE. Only a system

with five full-range (large) speakers plus a subwoofer can directly reproduce these formats. However, almost all
commercially available center channel speakers are small and incapable of reproducing the lowest bass
frequencies without distortion or even damage to the speaker. Many people also use small speakers in the rear of
their system, while others use small speakers all around. Use of a subwoofer is almost mandatory when using five
small speakers, but people with at least two large speakers may or may not choose to use a subwoofer. Some
people may not use a center channel or surround speakers at all. In order to handle any possible combination of
large, small, or missing speakers, a home theater system must contain good bass management, a concept often
missing from two-piece systems where the Dolby Digital or DTS decoder is separate from the preamp. Your
processor contains a complete bass management system. You can use as few as two large front left and right
speakers or two small left and right speakers plus a subwoofer or as many as seven full range speakers plus a
subwoofer or any combination in between without missing any information. Wherever small speakers are used the
bass management system prevents low bass information from going to that speaker (“high pass”). This bass
information is rerouted to a speaker that can handle it, usually a subwoofer, but it can also send center, surround,
or LFE bass to large front speakers if no subwoofer is available. When center or surround speakers are not used
at all, the missing channel is sent (“down mixed”) to the front speakers.

Preamp - A preamp typically includes the capability to select from a number of sources, adjust volume levels and

route the data to an amplifier. Your processor includes a high quality preamp.

Processor - A processor typically includes the capability to decode one or more surround formats, and convert

between digital and analog as required. Your A/V system controller includes a high quality processor capable of
decoding the surround formats described above.

Zone - A zone is usually a room that has speakers installed in it. Your processor includes a full preamp/processor

for Zone 1 (A) plus an additional analog stereo preamp for Zone 2 (B). This allows, for example, watching a Dolby
Digital movie in zone one while simultaneously using the built-in AM/FM tuner in another room.

Amplifier - An amplifier takes the output of a preamp/processor and increases its level to that necessary to drive

a speaker.

Speakers - A surround sound system use to typically use 5 speakers located left front, center front, right front,

right surround, and left surround plus a subwoofer located anywhere in the room. With the new developments in
surround technology from companies such as Dolby Laboratories, DTS, and Lucasfilm, it is now possible to
improve spatial expressions with an additional channel of information for use with a 6th and/or 7th surround back
speaker. Although best results are achieved using seven large speakers plus a subwoofer, this is not always
practical. Excellent results can be achieved using small and/or fewer speakers, as long as you go through the set
up procedures described later in the manual. Your processor includes the capability of reproducing up to 6.1
channels of surround information.

Component video vs. S-video vs. Composite video - Composite video is the oldest standard for color video. It

combines the luminance (brightness or black-and-white) and chrominance (color) information onto a single
conductor. These signals must be separated again for display resulting in some degradation of the video quality.
S-video is a newer standard that uses separate conductors for the luminance (Y) and chrominance (C)
information resulting in better video quality. Component video is the newest form of video introduced with DVD.
This video format uses separate conductors for luminance (Y), red - luminance (R - Y), and blue - luminance (B ­Y). Using these signals a component video capable monitor allows for even better and higher resolution video
quality. Your processor is capable of switching composite and S-video with no support of component video
signals. Also, you unit cannot convert between video types.

It’s tempting to just plug in your new A/V processor and have great sound pour out. Before you do that, take a few
minutes to plan out how you want the processor to fit into your audio/video system. Ask yourself the following
questions:

y What source components do I want to connect to my processor? (CD, VCR, etc.)

y What equipment will be receiving the audio and video? (TV monitor, Speakers, etc.)

The answers to your questions determine how many cables you need to connect to the back of the processor.
Good preplanning equals great sound. Keep these recommendations in mind:

y List all components in your system and indicate which jacks of the processor each component will be

connected to. Your processor has seven sets of inputs. It is convenient to connect a DVD player to the input
labeled DVD or a VCR to the input labeled V1 or TAPE, etc. However, your equipment may differ from the
labeling on the back of your processor. In most cases you can connect any type of source to any input (see
FREQUENTLY ASKED QUESTIONS). For example, if you don’t have a satellite receiver you can connect a
DAT player or a second cassette deck to SAT. You can also reprogram the source name that will appear on
your processor’s front panel and on-screen display (see SYSTEM SETUP - INPUTS)

y Also note the length of the cable for each component’s connection and describe how it should be routed or

draw your routing scheme below your list. You may want to label each cable with a name or number at both
ends. Use high quality connections to maintain high quality audio and video.

y Think about the type and length of cable you need and obstacles in the cable’s path (doorways, furniture,

walkways, etc.). To decide which ones are right for you talk to your dealer about the various cable products
that are available.

y For safety, keep all cables out of high traffic areas (hallways or doorways) and away from equipment that

radiates power, including amplifiers, power cords, heaters, etc.

y If you might expand your audio/video system later, keep these ideas in mind as you plan current cable runs.

y To provide the best tuner reception, make sure the antenna is at least several feet away from the processor

and any other equipment that may produce high frequency interference such as Personal computers, CD
players, halogen lamps, etc.

Take a look at the back panel of the processor. You will notice that the RCA-type audio input and output
connectors are identified by colors, red for right channel and white for the left channel audio. Composite video
input and output connectors are identified by yellow. Coaxial digital inputs are identified by orange. The surround
outputs are the Black connectors.

DVD Audio using the Coax digital inputs (optional) – your processor allows for an option to connect a 5.1
DVD Audio or other 5.1 surround format device, to the processor’s DVD Audio input when NO coax digital inputs
are to be used. This option calls for the setting of a push button switch internal to the unit. Please contact

B&K customer service for further details if this option is desired.

Attach one end of an audio interconnect cable to the center output on the DVD Audio source device, then attach
the other end to the Center (TV-V3) DVD Audio input on the processor. Repeat for the Left surround (V2) and Left

DIGITAL CONNECTIONS

Connect digital inputs (DVD, VLD, etc.) to the processor. You will need either coaxial or optical digital inputs to
play Dolby Digital (AC-3) or DTS surround sound processing. Digital connections are also recommended for PCM
sources. If your source has both optical and coaxial
outputs connect only one.

Coaxial digital inputs - standard RCA type connectors.
Attach one end of your digital coaxial cable to your source
coaxial digital out and the other end to the appropriate
processor coaxial digital (orange) input.

Optical digital inputs - First, remove the cap on
the optical digital input. Save the cap. Attach one
end of your digital optical cable to your source and
the other end to the appropriate digital input on the
back of the processor.

Connecting A Laser disc Player - Dolby Digital
(AC-3) laser discs use a special technique called AC­3 RF to encode the Dolby Digital bitstream. If the
laser disc player is capable of playing back Dolby
Digital discs it will have a separate output for this
bitstream in addition to the normal coaxial and/or
optical outputs. Do not connect the AC3-RF output
directly to your processor. The AC-3 RF bitstream
must first be converted to a normal (non-RF) Dolby
Digital type signal. It is recommended that a B&K
DT-1 be used to convert and select between the
Laser’s AC-3 RF and PCM/DTS signals. The output
from a DT-1 will automatically select between the
connected PCM/DTS bitstreams and the converted
AC-3 RF Dolby Digital signal. Other AC-3 RF to
Dolby Digital decoders may not make this switch

The Control outputs are programmable for each source in your system (see “Advanced Setup”). However, the
processor provides the following factory preprogrammed setup that should serve for most standard system
applications.

Control 1 - HEADPHONE - On (+12 VDC) when Zone 1 (A) is on and not in Headphone mode, off when Zone 1
(A) is off or in Headphone Mode. This mode may be used for controlling external amplifiers or powered
subwoofers in Zone 1 (A).

Control 2 - Zone 2 (B). On (+12 VDC) when Zone 2 (B) is on, off (0 VDC) when Zone 2 (B) is off. This mode is
used for controlling external amplifiers, projection screens, etc. in Zone 2 (B).

Control 3 - Z1 + Z2. On (+12 VDC) when Zone 1 (A), Zone 2 (B), or both zones are turned on. Off (0 VDC) when
both zones are off.

Control 4 -REMOTE. It will repeat a received 38 kHz modulated IR signal. The processor will transmit received IR
signals even in sleep mode.

Note - The control outputs can output a maximum of 50 mA. Check to see that the source you are connecting to
the control out requires 50 mA or less current.

WARNING - Not all manufacturers adhere to the +12 VDC control specification. Check to see if your
sources control inputs are +12 VDC compatible. Do not connect your processor’s control outputs to a
source with control or remote inputs rated at +5 VDC or other voltage rating. Damage to your source may
result.

IR Inputs - Your processor can be controlled by a directly connected IR repeater system in combination with or in

place of the supplied remote control. Connect your IR input cable to the processor using a mono 3.5 mm jack
shown above. The plug must be wired as tip (+) and the long barrel section (-). The inputs are standard 38kHz
modulated IR type with a voltage range of +5 to +12 VDC.

FREQUENTLY ASKED QUESTIONS

My collection of equipment differs from the labels on the back of my processor, how can I hook them up?

Your processor provides 5 identical sets of inputs - V1, V2, DVD, CD, and SAT. Each of these has analog
audio, composite video, S-video, coaxial digital audio, and optical digital audio. It is convenient to connect
components as labeled on the back of your processor, but since all the inputs are identical, you can connect any
compatible source to any set of inputs. For example, you can connect a DAT player to V1 instead of a VCR. You
can program your processor to display any 5-character name for any input (see System Setup - Inputs).

The sixth input, TV, is identical to the others except that there is no optical digital. You can also connect
portables to any other coaxial digital input using adapters or special cables. If you have a source with only optical
digital output don’t connect it to TV.

The seventh input, TAPE, has analog audio, composite video and S-video, but has no digital inputs. It is
primarily intended for analog recorders such as VCRs or cassette decks. If you have a three-head cassette or
reel-to-reel tape deck you will prefer the TAPE input since it allows a full tape monitor capability. Tape monitor
allows you to listen to what is actually on the tape as you are recording it. The V2 input also provides full tape
monitor capabilities for Zone 2 (B). If you don’t use Zone 2 (B) you can use V2 as a second independent analog
tape monitor loop. V1 includes a line level output but does not provide true tape monitor capability.

My DVD player (or other source) has both optical and coaxial digital outputs. Should I connect both?

No, connect only one digital cable per source.

Do I need an AC-3 RF demodulator (B&K DT-1 or equivalent) to playback Dolby Digital
DVDs?

No, this is required only for Dolby Digital laser discs.

Do I need an AC-3 RF demodulator (B&K DT-1 or equivalent) to playback DTS laser discs?

No, this is required only for Dolby Digital laser discs.

Do I need to connect both analog and digital audio from my DVD player (or other digital audio source) to
the processor?

In general, it is simpler to connect both. However, if you can meet all of the following criteria you need
only connect digital:

1. I do not use Zone 2 (B). (Zone 2 (B) is analog only - if you use Zone 2 (B) you must connect both left and
right analog to hear audio.)

2. I do not own any old laser discs. (Early laser discs contained only analog audio tracks - you must connect
both left and right analog audio to play these back.)

3. I do not use Tape Monitor. (It is possible to tape digital-only sources. However, if you wish to listen
directly to the tape as you are recording - you must connect both left and right analog audio - the tape monitor
loops are strictly analog.)

If the tape monitor loop is strictly analog, how do I make an analog recording of a digital-only source?

Do not select TAPE. Select the source you wish to record. Select STEREO 9, the LtRt mode. If that
source is digital, the converted digital-to-analog will appear at the tape and V1 outputs. V2 out, like Zone 2 (B)
out, is analog only. (See also Operation - Zone 1 Operation - Mode.)

I want to make direct digital recordings from my CD player (or other digital source) on my CD Recorder,
DAT (or other digital recorder). Can my processor make this connection for me?

Yes, your processor’s digital outputs act much like the analog tape outputs. When you select a source, if

that source has a digital connection to your processor, then that digital signal will appear on the processor’s
coaxial and optical digital outputs. Simply connect all of your sources digital outputs to your processors digital
inputs. You can then connect up to three digital recorder inputs to your processor’s three digital outputs.

20

13258 0303

My laser disc player (or other digital source) has only optical output, but my CD recorder (or other digital
recorder) has only coaxial input. Do I need some sort of converter to make direct digital recordings?

No, your processor will convert optical to coaxial and coaxial to optical. The currently selected digital input
(optical or coaxial) will appear at both of the processor’s digital outputs (optical and coaxial).

Do I need to connect both analog and digital audio from my processor to my CD, DAT, MD, recorder,
etc.?

In general, yes. If all of the sources you wish to record are digital, then you need only connect digital to
your recorder. However, your processor does not provide digital outputs for non-digital inputs. If you wish make a
digital recording from an analog-only source you must also connect analog from your processor (Tape or V1 out)
to your recorder.

Can I connect a phonograph directly to my processor?

No, you will need a separate outboard phono preamplifier. The output of the phono preamp can then be
connected to any analog input on your processor. We recommend our Phono 10 phono preamp. In addition to it’s
superb analog audio processing, it has an option for S/PDIF coax output. Talk to the dealer where you purchased
your processor.

Do I need to connect both S-video and composite video to my processor?

If all of your video equipment has S-video then you need only connect S-video. S-video is a higher quality
video format and you will probably not want to use composite. If all or most of your video equipment is composite
then it is simplest to just connect the composite and omit S-video.

Can I connect mixed composite and S-video sources?

Yes, but your processor will not convert S-video to composite or composite to S-video. If your monitors
and VCRs accept only composite video then there is no point in connecting S-video from other sources. If you use
mixed S-video and composite sources you must connect both

S-video and composite to your monitors and VCRs.
You will need to change your monitor or VCR S-video / composite inputs manually when you change sources.
This can normally be done via the monitor’s or VCR’s remote control (or the supplied universal remote). Some
monitors or VCRs may require you to physically disconnect S-video before they will accept composite video.
Some monitors are capable of automatic switching between S-video and composite. Your processor must be
setup properly in order to work with auto switching monitors - refer Setup Displays.

To assist you, the processor’s on-screen display will tell you what video is currently selected whenever
you change sources or hit the SEL (remote) or ENTER (remote or front panel) key, but it cannot switch your
monitor or VCR input for you. If you are watching S-video, but the source is composite video only, you will see

“Switch Monitor to Composite” on your Monitor. If you are watching Composite video but your source is S-video
only, you will see “Switch Monitor to S-video” on your monitor. These displays appear only if your processor is
setup for manual monitors.

Can I connect mixed composite and S-video monitors and VCRs?

Yes, but you must connect both S-video and composite from all of your sources - your processor will not
convert between S-video and composite. Refer to the previous question if not all of your sources have both S­video and composite outputs.

For example, it is common to have an S-video monitor and a composite VCR. Connect the monitor to the
Zone 1 (A) S-video and composite outputs and the VCR to the V1 or TAPE composite output. The composite
inputs will appear at the composite outputs for TAPE and V1. (The S-video inputs also appear at the TAPE and
V1 S-video outputs, but, in this example, they are not connected.) To prevent feedback, TAPE IN will not appear
on TAPE OUT and V1 IN will not appear on V1 OUT - this also applies to the audio outputs. Zone 2 (B) works the
same for Zone 2 (B) OUT and V2 OUT with feedback prevention on V2.

Things get a bit more complicated for the Zone 1 (A) output because it contains your processor’s internal
on-screen display system. You must be sure that you tell your processor if you have a monitor which can
automatically switch between S-video and composite outputs, or one which must be manually switched (see
Setup Displays)

SETUP

For best results, perform the following set up procedure when you initially install your processor and anytime you
change or add sources, speakers, etc. or when you rearrange your listening area

THE MENU SYSTEM

Setup of your processor will require you to navigate through the menu system. We recommend that you use a
video monitor connected to the Zone 1 (A) output along with the remote control provided with your processor. It is
also possible to set up your processor from the front panel. Do not leave your video monitor on with the processor
in the menu system for long periods of time. This can result in permanently burning the menu display into your
monitor’s screen. This would take several hours so there is no danger of it happening during normal setup
procedures. The following are general instructions for using the menu system. A complete guide to the menu
system is included at the back of this manual.

MENU - If you are not already in the menu system, the MENU button will activate the menu system. Once you are
in the menu system, the MENU button will return you to the next higher-level menu or, if you are already at the
highest level, it will exit from the menu system.

UP/DOWN ARROWS - Once you are in the menu system, use the UP/DOWN ARROWS to move to the desired
menu selection. The currently active menu line is highlighted in a contrasting color.

SEL (remote) or ENTER (remote or front panel) - Some menu selections cause another menu to be activated.
Use the UP/DOWN ARROWS to move to the desired menu line. Pressing SEL or ENTER will activate the next
menu.

NUMERIC KEYS (remote only) - From the remote control you may also go directly to a menu line by typing the
corresponding line number. If there is another menu below that line it will be activated immediately (no ENTER
required).

LEFT/RIGHT ARROWS (remote) or VOLUME KNOB (front panel) - Some menu selections allow you to change
one of the processor settings. Use the UP/DOWN ARROWS to move to the desired menu line. Pressing the
LEFT/RIGHT ARROWS will change the setting. There are no LEFT/RIGHT ARROWS on the front panel. While in
the menu system, the VOLUME KNOB acts as the LEFT/RIGHT ARROWS. This means that you will not be able
to adjust the volume from the front panel while in the menu system. The remote control volume will work in most
menus.

TEXT EDITING - some menu selections will require you to edit text. Use the UP/DOWN ARROWS to change the
current (blinking) character. Use the LEFT/RIGHT ARROWS (or VOLUME KNOB) to move to another character
position.

EXIT (remote only) - From the remote control you may instantly EXIT the menu system.

UNIVERSAL REMOTE - Remember that when you press a source button (DVD, CD, etc.) the remote now
controls the selected device. To return control to your processor, you must press B&K or AUDIO. ALWAYS
check that your remote is set to B&K or (AUDIO) before attempting to control your processor. B&K or
(AUDIO) will be displayed in the remote’s LCD window.

Speakers

The speakers menu lets you tell your processor how many speakers you have in your system, the relative size of
the speakers, and their location in the room. This is the most important setup procedure you will perform. The
processor comes from the factory setup for 7 small speakers and a subwoofer. If this does not match your
speakers then audio information will be lost. For example, if you do not currently have a center channel speaker
and you do not perform this setup procedure, the center channel information will be lost. If you perform this setup
correctly, the processor will know that you have no center channel speaker and send this information to your front
left and right speakers (along with the normal front left and right information) so no audio information is lost.

Speaker Size

Speaker size generally refers to the size of your speakers. Audio material, particularly Dolby Digital and DTS
movies, often contain large amounts of bass. If this bass information is sent to small speakers that are incapable
of reproducing so much bass, then the bass information will be lost or distorted. MANY SMALL SPEAKERS MAY
BE DAMAGED BY TOO MUCH BASS. By telling your processor the size of your speakers, it will be able to
intelligently route the bass to speakers that can reproduce it correctly. Typically, all bookshelf or satellite speakers
are considered small. Smaller floor standing speakers with single woofers 8” or less should also be considered
small. Floor standing speakers with 10” or larger woofers or multiple smaller woofers may be considered large.
These are general guidelines only - if you are unsure consult your speaker manufacturer or check with the dealer
if they are unsure. If you have all small speakers we strongly recommend use of a subwoofer. If your front left and
right speakers (or more) are large then you may not require a subwoofer, but you may still get better results using
a subwoofer, especially with Dolby Digital and DTS movies. All THX certified speakers are small, regardless of
their physical size, and should be used in audio systems along with a subwoofer.
