SAFETY PRECAUTIONS

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 a 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 a 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-serviceableparts inside. Refer servicing to qualified service personnel.

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

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

Prevent damage to the power cord. Replace the power cord if it becomes damaged in any way. Always grasp the plug on the power cord when plugging or unplugging the receiver 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.

Protect the receiver from impact and place the receiver on a level surface.

The receiver is equipped with raised feet to provide ventilation, reduce acoustic feedback, and protect against scratching the surface the unit is resting on. B&K advises against removing the feet.

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

The receiver should be located away from sources sensitive to heat.

Do not perform any internal modifications to the receiver.

Always connect the receiver's power cord to a dedicated 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.

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

•System impedance SHOULD NOT fall below the nominal impedance of the amplifier stage, i.e two 8Ω speakers in parallel = 4Ω (system impedance). Minimum stability refers to the periodic audio passages that demand large amounts of current at which time the output impedance drops.

The receiver should be serviced by qualified personnel when:

A.The receiver is not functioning properly.

B.Objects have entered the chassis.

C.The receiver was exposed to rain or any other type of moisture.

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

AUDIO / VIDEO OVERVIEW

Definitions

Sources - A source is considered any device that can be connected to the audio/video receiver or processor and transmit a signal that can be seen or heard. Typical sources include DVD players, satellite boxes, CD players, etc. Your receiver can provide audio from its built-inAM/FM tuner. Your receiver is designed to accommodate a wide range of audio and video signals.

Zone - A zone is usually a room or section of the house that has speakers and/or video installed in it. Your receiver includes a full preamp/processor for Zone A , the main theater zone, plus an additional analog audio and video preamp for Zone B - the second zone. Two zones allow for watching a Dolby Digital movie in the main theater while simultaneously using the built-inAM/FM tuner in the second zone.

Amplifier - An amplifier takes the output of a pre-amplifier/processorand increases its levels necessary to drive a speaker. In a receiver the amplifier is combined into the same box with the processor. B&K employs high current amplifiers in their receivers. These amplifiers are also available as separate components.

Speakers - A surround sound system typically uses 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 and DTS, it is now possible to improve spatial expressions with an additional channel of information for use with a 6th or 7th surround back speaker(s). 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 setup procedures described later in the manual. Your processor includes the capability of reproducing up to 7.1 channels of surround information.

A/V Preamplifier - An A/V preamplifier has the capability to select from a number of A/V sources, adjust volume levels and route the audio to an amplifier and video to a video monitor. An A/V preamplifier requires the use of an external power amplifier.

Surround 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 receiver includes a high quality MotorolaTM processor capable of decoding the various audio surround formats.

Composite video vs. S-videovs. Component video - Composite video is the oldest standard for color video. It combines the luminance (brightness orblack-and-white)and chrominance (color) information onto a single conductor. At the monitor, this composite video signal must be separated again for it’s display which results in some degradation of the original video quality.S-videois a standard that uses separate conductors for the luminance (Y) and chrominance (C) information resulting in better video quality. Component video is a form of video which first became popular with the introduction of the DVD player. Most component video signals are a variation of the red, green and blue signals that make up a television image. The simplest type, RGB, consists of the three discrete R, G & B signals sent over three video cables. Another type consists of R- Y,B-Yand Y (also known as YUV), that is also sent over three video cables. Y is the luminance channel,R-Yis the red component minus the luminance information, andB-Yis the blue component minus the luminance information. Your receiver is capable of switching composite,S-videoand component video signals, and converting between signal types. Your A/V receiver is capable of transcoding composite video andS-videoto component YUV video signals.

Transcoding - Video transcoding is the process of converting one video format to another. Video transcoding is a new technology brought about by the need to integrate these many different video formats. Video transcoding does not change the resolution of the original video signal and allows different video formats to be viewed on one video monitor. Video transcoding research is being driven by the need to integrate video technologies pertaining to computer networks, cell phone, PDAs, television and satellite. Your A/V receiver is capable of transcoding composite video and S-videoto component YUV signals.

AUDIO / VIDEO OVERVIEW

 

 

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 receiver from the source. Analog signals exactly represent the sound you will hear through a continuously varying voltage. Audio cassettes are analog recordings and are normally delivered to your receiver 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 receiver through a single 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-channelaudio. In Dolby Digital and DTS (see "Audio and 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 receiver 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 receiver 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 receiver before being output to 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 receiver. It is impossible for the receiver 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 receiver can, therefore, reproduce the signal with the greatest possible fidelity. We recommend you use digital signals whenever possible. Also Dolby Digital and DTS (see "Audio and Surround Formats" below) work only with digital signals.

AUDIO AND SURROUND FORMATS

Your source material will be played back on your B&K processor in one of the following possible formats described below. Each format can be used for various listening conditions.

Monaural (Mono) - Mono is the oldest format available. It contains a single, full range audio channel. Modern recordings are seldom made in this format, however older movies and music may only be available in this format. You may get mono from any source - digital or analog. Your receiver can produce mono in one to seven channels depending on speaker and audio setup. Since all modern sources are stereo, the mono information is usually replicated on both the left and right channels.

Stereo - Stereo contains two discrete, full-rangefront left and right 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 receiver can produce stereo in two to seven channels, depending on speaker and audio setup.

Dolby Digital 5.1 - Dolby Digital 5.1 is a method of transmitting and storing 5.1-channelsoundtracks via digital media such as DVDs, digital cable, digital broadcast TV (DTV), and satellite transmissions. Dolby Digital 5.1 is transmitted over the optical digital or coax digital connections. Unlike the Dolby Surround encode/decode Pro Logic process, which sacrifices channel separation to get surround onto any stereo soundtrack, Dolby Digital 5.1 is a discrete system that keeps the multiple channels fully separated throughout the encoding and decoding processes. In addition to havingfull-rangefront left, center, right, left surround, and right surround channels, Dolby Digital 5.1 soundtracks carry a sixth (“.1”) channel recorded with lowfrequency effects. For more information on Dolby Laboratories, please visitwww.dolby.com.

Dolby Digital Surround EX - Dolby® Digital Surround EX™ provides a third surround channel on Dolby Digital movie soundtracks. The third surround channel can be decoded at the cinema's or home viewer's option for playback over surround speakers located behind the seating area. The left and right surround channels are reproduced by surround speakers to the sides. To maintain compatibility, the back surround channel is matrix-encodedonto the left and right surround channels of an otherwise conventional 5.1 mix, so no information is lost when the film is played in conventional 5.1.

A 5.1-channelsoundtrack can be played on a5.1-speakersystem. But it is not always understood that it can also be played on a 6.1- or a7.1-speakersystem. To do this, the two surround signals on the 5.1 soundtrack are spread across the three or four surround speakers. This distribution can be accomplished by a Dolby Digital EX decoder, or other proprietary methods provided in home theater equipment by various manufacturers.

Dolby Pro Logic II - Pro Logic II brings exciting features and advanced performance for decoding the many thousands of existing Dolby Surround programs, making them sound more like a discrete Dolby Digital 5.1- channel version than ever before. Pro Logic II is able to decode the thousands of existing Dolby Surround movies and TV shows already on the shelf, compatibly, and with enhanced image stability. The improvements in decoding techniques mean that the discreteness of the sound field elements are better preserved in the decoding process than was possible with the standard Pro Logic technology. Pro Logic II offers a music mode to expand stereo non-matrixrecordings into afive-channellayout in a way that does not diminish the subtlety and integrity of the original stereo recordings.

Dolby Pro Logic IIx - Dolby Pro Logic IIx is a new extension of Dolby Pro Logic II technology. This highly sophisticated algorithm processes native stereo audio signals and 5.1-channelmulti-channelcontent to produce 6.1 or 7.1 output channels. Dolby Pro Logic IIx expands the choice in playback system configuration (allowing 5.1, 6.1, or 7.1 playback channels) and, when incorporated into an A/V receiver or processor such as B&K, it allows a convenient upgrade path from a traditional5.1-channelsound system to 7.1 output channels. The two surround back channels are decoded into stereo.

Center width - The Center Width control allows the user to modify the amount of steering that is applied to Center signals. As steering is reduced, the Center signal originates increasingly from the Left and Right speakers, and is concurrently reduced in the Center speaker. The purpose of the Center Width control is to reduce the “hard Center channel” phenomenon that sometimes results from Center signal steering of stereo encoded soundtracks.

Panorama - The function of the Panorama mode is to create a more enveloping front surround field. It is equally useful when applied to Dolby Pro Logic IIx processing.

Movie or Music - Surround programs are primarily movie based. Even TV dramas are essentially mixed like movies. When programs are mixed in surround, they are monitored through the surround decoder that will be used for playback in the cinema or home. Movie mode is the reference decoder mode for any such surround-encodedprogram.

Music, on the other hand, is commonly mixed for stereo playback, and no surround monitoring is done by the mixer. When played back through a surround decoder, the results may not always be optimal. This is because a movie-typedecoder is expecting a signal that has been deliberately surround encoded. Music mode brings the benefits of a highly natural and balanced multichannel surround sound field to content that was not specifically encoded for surround playback.

DTS 5.1 (Digital Theater Systems) - DTS is a multi-channeldigital audio compression format transmitted over optical digital or coaxial digital connections. DTS is dedicated to delivering the “Ultimate Entertainment Experience.” DTS has created amedia-deliveryformat that makes audio tracks sound more dynamic, more realistic and more closely matching the original than other digitally encoded soundtracks and consumer media. Coupled with themulti-dimensionalplayback benefit of surround sound technology, DTS audio quality dramatically improves and enhances content. DTS 5.1 is an ultra realistic home theater environment, it delivers discrete channel precision plus theall-envelopingrealism for which DTS is renown. For more information on the various DTS formats, visitwww.DTSonline.com.

DTS NEO:6 - An advanced matrix decoder. It will take any two-channelsource and expand it into five or six channels, depending on the user's speaker layout.Two-channelsources include VHS tapes, broadcast television, stereo CDs and DVDs. DTS Neo:6 provides separate, optimized modes for stereo music materials and matrix surround motion picture soundtracks. DTS Neo:6 also decodes acenter-surroundchannel from Extended Surround matrix soundtracks. Music and movie filters can be applied to the NEO:6 decoder. The differences between these two filters apply primarily to the differences in the type of soundtrack being played back.

DTS-ES6.1 (Extended Surround) - The Extended Surround (ES) adds a discrete backcenter-surroundchannel to the existing5.1-channelarray.DTS-ESDiscrete 6.1 is the only home format that can deliver 6.1 discrete channels.DTS-ESis fully compatible with all types ofmulti-channelsystems. All sounds will be heard even when played back on a system with less than 6.1 speakers

DTS Neo:6 Movie - Movie steers decoded material toward the center channel while preserving the integrity of the stereo mix. When listening to movies using the DTS Neo:6 movie decoder with stereo TV shows or other surround-encodedprograms, there is further enhancement to soundfield directionally, which is close to the quality of discrete6.1-channelsound. Conventional narrow band monaural surround channel is played as stereo with a more realistic feel and movement.

DTS Neo:6 Music - Music steers the effects into the soundfield by utilizing the surround channels for a more spacious, 3-dimensionalfeeling. When listening to music using the DTS Neo:6 music decoder, stereo music recordings are able to provide a wide and deep soundfield. DTS Neo:6 music decoder allows you to tailor the Center Image to your own preference. The Center Image control allows the sound of the center channel to be placed between its own speaker and the left and right front speakers.

Bass Management - Dolby Digital and DTS-ESformats may contain up to 6 full range channels plus an LFE (Low Frequency Effects) channel. Only a system with sixfull-range(large) speakers plus a subwoofer can directly reproduce these formats. However, almost all commercially available center channel speakers and bookshelf speakers are considered small and incapable of reproducing the lowest bass frequencies without distortion or even damage to the speaker. Many people use small speakers in the rear of their system, while others use small speakers for all channels. Some people may choose not to use a center channel or surround speakers at all. Use of a subwoofer is mandatory when using small speakers to reproduce low frequencies. In order to handle any possible combination of large, small, or missing speakers, a home theater system must contain good bass management. Your B&K receiver contains a complete bass management system. You can use as few as two large (full range) front left and right speakers or two small front left and right speakers. Wherever a small speaker is used, the bass management system filters low frequency information from going to that speaker ("high pass"). This bass information isre-routedto a speaker that can handle it, usually a subwoofer. If no subwoofer is present, it can send the low frequency and LFE to large front or surround speakers. The bass management crossover point can be adjusted by the user according to the types of speakers being used.

Notch Filters (Parametric Equalization)- Notch filters are used to enhance the frequency response of a given room. The full range frequency spectrum in an ideal scenario is completely flat. This means that there is no variation in the decibel level between any of the frequencies as you sweep up or down the frequency range. This type of response is almost impossible to achieve. Due to the physical geometry of any given room, the sound waves will bounce off walls, doors or windows within the room. This reflection of sound

waves is a desirable effect to a point. Different locations in the room will have waves that collide with one another. This collision can cause a superposition (addition or subtraction) of the audible wavelength. In either case, these locations are referred to as nodes. If a positive node occurs in the primary listening position, that frequency drowns out all other frequencies at that location, resulting in limited frequency response for that location in the room. A node can occur at any frequency, however nodes are much more prevalent in the lower frequency ranges (below 130Hz). In these lower frequencies, the wavelengths are physically long enough that a superposition can have a more dramatic effect than frequencies at a higher (shorter) wavelength. A notch filter provides a means by which the receiver can effectively ‘notch’ out resonant frequencies to achieve a balanced frequency response for a given room. Once the frequency response has been returned to its reference level, a fuller, more dynamic audio reproduction can be heard. B&K supports three separate notch filters for the frequency range of 20 Hz to 300Hz.

DVD-Audio(also referred to as MLP) -DVD-Audio(also referred to as MLPTM) - MeridianR Lossless Packing. MLPTM is a lossless compression system forhigh-qualitylinear PCM audio. ForDVD-AudioMLPTM performs lossless compression of 1 to 6 channels of 14 to24-bitmaterial sampled at rates between 32kHz and 192kHz. With lossless compression, the decompressed signal isbit-for-bitidentical to the master, just 'packed' into a lower data rate which ultimately results in a reduced size to be stored on the disc. Currently,DVD-Audiocan only be delivered to your receiver via the analog 5.1 inputs. Sound will normally come from your front left, front right, center, left surround, and right surround speakers, as well as your subwoofer, but your processor can produce sound in one (mono) to seven channels. Dolby Pro Logic IIx is used to matrix the surround back left and surround back right channels if a seven channel configuration is used.

SACD (Super Audio CD) - Is a new audio recording format aimed at providing higher fidelity audio reproduction than the compact disc. It was developed by Sony and Philips . The sound of SACD comes directly from Direct Stream Digital (DSD) recording technology. SACD disks generally contain a 2-channelstereo mix. Many also contain a 5.1 surround sound mix. DSD's simplified mechanism for recording and playback results in a frequency response over 100kHz and a dynamic range over 120dB across the audible frequency range. DSD increases the resolution of music by more closely following the original wave form of the music, which results in music reproduction that is remarkably pure and faithful to the original.

Cinema Processing - Cinema is an exclusive set of standards and technologies that can be applied to any B&K surround mode. In a typical movie theater the front left, right, and center speakers are located behind the screen. The screen tends to block high frequency information. Therefore, movie soundtracks often have boosted high frequency content to compensate for the effects of the screen. This boost can cause some soundtracks to sound overly bright in a home theater where speakers are typically not behind a screen. B&K cinema mode adjusts the front left, right, and center frequency response to compensate for the boost applied for the movie theater.

High Current Amplifiers - A high-currentamplifier is capable of delivering power into low impedance speakers without going into protection and/or shutting down. Ideally, an amplifier's output power would double every time the load presented at its output is halved. In a typicalamplifier-speakercircuit, voltage and current are delivered to a very complex load consisting of speaker drivers, resistors, inductors, and capacitors. Voltage may be thought of as the potential to do work, and current as what actually flows to do the work. Although basic power may be calculated by the simple multiplication of voltage and current, it is the delivery of the power from the amplifier to the complex speaker load that accounts for why two amplifiers may have the same power rating into identical impedances (speaker loads), but deliver a significantly different sound quality. Some of these sound quality differences may include perceived loudness, depth, and clarity. High quality speakers can have nominal impedances from 8 - 2 Ohms. During very loud and dynamic audio passages, the speaker load may dip below 2 Ohms. These low impedance drops may cause a high voltage power amplifier with limited power storage capacity to sound harsh and distorted. Ahigh-currentamplifier operates with much less effort and typically does not have any problem with low impedance speakers. B&K amplifiers and receivers are High Current Power amplifiers.
