AUDIO MODES & SPEAKER SELECTIONS
B& K incorporates a state-of-the-art software and hardware system that will prioritize the incoming audio
signals (Plug n Play) and accordingly select the appropriate number of speakers, two-channel surround
decoder (Dolby Pro Logic IIx or DTS NEO:6) or multi-channel surround mode (Movie or Music) depending on
the user’s preference. Multi-channel encoded bitstreams (DTS and Dolby Digital) are automatically detected
and selected for any input. When a Dolby Digital or DTS multi-channel bitstream is detected, the number of
speakers in the speaker setup menu are selected automatically. Plug n Play will give priority to digital
bitstreams. If there is no multi-channel or two-channel digital bitstream present, Plug n Play will revert to the
analog audio (left and right) inputs using the default audio mode.
This receiver includes five audio listening modes; mono, stereo, surround, cinema and DVD-audio. Each
input (7 inputs) can be configured for each audio mode (4 audio modes), plus the DVD-Audio mode (see
page 29). The receiver will store user preferences for each audio mode resulting in a one touch solution for
recalling specific settings for various types of multi-media formats. For normal operation, the Setup Inputs
preferences should be configured for the “favorite” (default) setting for each input. Occasionally, you may
want to change the audio mode or speaker selection being used with an input. To quickly change the audio
mode simply select Mono, Stereo, Surround, Cinema or DVD Audio via the remote control or the front panel
Mode button. In addition, you may choose an audio listening mode immediately followed by a speaker selec-
tion. For example pressing STEREO-7 will select 7 speaker stereo mode. Pressing SURR - 5 will select 5
speaker surround. If you are listening to a 2-channel bitstream, you may change the surround decoder
(Dolby Pro Logic IIx or DTS Neo:6) and the operating mode of the surround decoder (Movie, Music, Game)
using the corresponding buttons on the remote. From the front panel use the MODE button to step through
surround modes and decoder types. Use the UP and DOWN arrows to select the desired number of
speakers.
Audio Mode Usages
MONO - The audio signals are summed or downmixed to produce a single mono channel which can then be
distributed evenly to the desired number of speakers. It is also useful in the case of a large listening group
when it is difficult to put everyone near the optimum listening position. To quickly recall the mono mode from
the remote control, press the MONO button then the number of desired speakers 0-9 (see table page 47).
From the front panel, press the MODE button then the up and down arrows to select the number of speakers.
STEREO - The unmodified Left and right audio signals are evenly distributed to the desired number of left
and right speakers. The center channel speaker receives a mono mix. Use this mode for true stereo listening
or for expanding the stereo image to additional speakers. To quickly recall the stereo mode from the remote
control, press the STER button then the number of desired speakers 0-9 (see table page 47). From the front
panel press the MODE button, then the up and down arrows to select the number of speakers.
SURROUND - This mode is used to extract multi-channel surround information from a 2-channel audio
source using one of the two available surround decoder types (DTS NEO:6 & Dolby Pro Logic IIx). To quickly
recall the surround mode from the remote control, press the SURR button then the number of desired
speakers 0-9 (see table page 47). To select surround from the front panel press the MODE button to scroll
through the audio modes, then the UP and DOWN arrows to select the number of speakers. Movie or music
mode have their own discrete IR command buttons for selection.
You have a choice of two methods for simulating multi-channel sound from a two channel source - Dolby Pro
Logic IIx and DTS Neo:6. These decoders use different formulas for creating the simulated multi-channel
soundfield. Each decoder type provides a MOVIE and a MUSIC mode. MOVIE places greater emphasis on
the back speakers and MUSIC places greater emphasis on the surrounds. Dolby Pro Logic IIx and DTS
provide an adjustable MUSIC mode. MUSIC mode adjustments are for the center image (width), surround
image (dimension), and front-to-surround image (panorama). Use the IMG+/-, DIM+/- and PAN+/- buttons on
the remote to adjust the various parameters for how the surround field is created. MOVIE mode is fixed and
has no adjustment options. Continued on next page...
