- six coaxial and five optical inputs, one coaxial (Z1, Z2) and one optical output (Z1). Control Outputs - four 12 VDC @ 50 mA outputs for turning on amplifiers and controlling external systems such as a projection screen or B & K amplifier.
The following is intended to familiarize users with common terms and applications of Home Theater equipment. Sources - your processor can provide audio from its built-in AM/FM tuner. It can also provide limited video from its on-screen menu system. You will want to connect a number of additional sources (VCR, DVD player, etc.) to your processor.
Page 9
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”).
Page 10
DTS NEO:6 – DTS Neo:6 is an advanced matrix decoder. It will take any two-channel source and expand it into five or six channels, depending on the user’s speaker layout. Two-channel sources 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.
Page 11
THX Surround EX ™ - Dolby Digital Surround EX is a joint development of Dolby Laboratories and the THX division of Lucasfilm Ltd. In a movie theater, film soundtracks that have been encoded with Dolby Digital Surround EX technology are able to reproduce an extra channel, which has been added during the mixing of the program.
Page 12
Bass Management - Dolby Digital and DTS-ES formats may contain up to 6 full range channels plus LFE. Only a system with six 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.

MAKING THE CONNECTION 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: What source components do I want to connect to my processor? (CD, VCR, etc.) What equipment will be receiving the audio and video? (TV monitor, Speakers, etc.)

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.
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.

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.
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 output along with the remote control provided with your processor.
SYSTEM SETUP You should always perform System Setup after first installing your processor and after adding/changing speakers or sources or rearranging your listening area. Check that the remote is in B&K mode. From Remote From Front Panel B&K or POWER SLEEP MENU MENU...

Ideally your speakers will be the same distance away from your listening area. However, physical limitations usually require placing the speaker in other than optimum locations. Your processor contains a means to electronically move each speaker’s location. This allows for superior reproduction of the directional cues available during the playback of movie or music.
Speaker level calibration allows you to equalize the volume levels of each speaker to make up for differences in speaker characteristics and distances from the listener to the speakers. For best results it is important that you perform this calibration when you initially install your processor, whenever you change speakers, and whenever you rearrange your listening area.

simple name for the preset, which you can then change before confirming the preset save. You may wish to defeat this automatic naming so that any custom names that you have entered will not get erased each time you save a minor change to a preset. Turning auto naming off means that the name that is already present in the preset will be re-used when you save a new preset to that location.
MEMORY BACKUP Your processor continually saves any settings you have made even if power is lost. However, you may wish to save a backup of your settings in case of inadvertent changes to them. To perform a backup, follow the procedure below.
The following outlines the normal day-to-day operation of your processor from the supplied universal remote or directly from your processor’s front panel. The universal remote is also capable of controlling other equipment and storing sequences of commonly used commands. Refer to the separate remote manual for details on these functions.
CHOOSING A SOURCE In general, the selected source will appear at the Zone 1 output, the TAPE output, and the V1 output. To prevent feedback, TAPE input will not appear at TAPE output and V1 input will not appear at V1 output. D V D A n a 2 .
ADJUSTING THE VOLUME Z1 Master Volume From Remote VOLUME + or VOLUME − MUTE Note: The front panel VOLUME KNOB is used to control multiple functions and, therefore, cannot always control the volume. The VOLUME KNOB may control volume in the menu system when not used for parameter adjustments.
AUDIO MODES Your processor is designed to work with 5 audio listening modes. Under normal operation you may simply select Mono, Stereo, Surround, THX or DVD Audio via the remote control. In addition, you may choose an audio listening mode immediately followed by a speaker selection. The table below shows how your processor will route audio with the various audio modes and speaker selection combinations.
Audio Mode description MONO Sums the incoming audio information to a single channel and routes it to the desired speaker. Use this mode for listening to the FM tuner with weak RF signal strengths. It is also useful in the case of a large listening group and it is difficult to put everyone near the optimum listening position.
When listening to movies using the DTS Neo:6 movie (cinema) decoder with stereo TV shows or other surround- encoded programs, there is further enhancement to soundfield directionality, which is close to the quality of discrete 6.1-channel sound. Conventional narrow band monaural surround channel is played as stereo with a more realistic feel and movement.
Special Considerations For use with multi-channel encoded bitstreams pressing of SURROUND or THX toggles between the Movie and Music playback options. For use with 2-channel analog or digital audio, pressing of SURROUND or THX allows sequencing through the six surround decoder types, Pro Logic Movie, Pro Logic Music, Pro Logic II Movie, Pro Logic II Music, Neo:6 Movie and Neo:6 Music.

With the wide variety of audio source material available today, i.e. single channel mono, 2 channel mono, 2 channel stereo, 2 channel surround and multi-channel encoded audio, we believe that the reproduction of this material is best handled in audio categories. We have decided to define five “audio modes” which are actually different Plug and Play modes of operating our audio processor.
EQUALIZATION ‘EQ’ Selecting an EQ function via the remote control - allows you to override how the audio is currently being processed. This is where you may set the Dynamic Range to either Normal (default) or Limited for late night listening while processing Dolby Digital or DTS bit streams.
For late night listening while processing Dolby Digital or DTS bit streams and a reduced dynamic range is desired. When the dynamic range is set to limited, compression is used to raise the average loudness of the dialog, and the program peaks will be restricted much in the style of conventional television audio. From Remote EQ then 1 SEL or ENTER...
ZONE ‘Z’ Use the Z (zone) function via the remote control - For use in a second audio zone, your processor comes equipped with a fully independent 2-channel analog pre-amp. The easiest way to control this second zone is with a dedicated Zone 2 (the factory default zone ID setting of Zone B is 2) remote available from B&K and other universal remote suppliers.
