Music Modes - Bryston SP 1 Series Instructions Manual

10. Stereo and Stereo Downmix Mode
If this button is selected and the supplied bitstream is more
than 2 channels, the decoder will automatically implement a
stereo downmix. Otherwise, analog or digital two channel
signals are passed as conventional stereo.
11. Mono and Mono Downmix Modes
If this button is selected and the supplied bitstream is more than
1 channel, the SP1 software will create a Mono mix of all signals.
Pressing this button repeatedly, will direct the mono signal to
different speakers, if your system has them available and the
SP1 was setup to recognize your speaker layout during initial
calibration. The options in order are:
Mono LR (Left, Right),
Mono Centre
NOTE: Downmix [stereo or mono] is a software based automatic mixing
function available within the SP1. This process exists because whenever
the number of active decoder outputs or loudspeakers selected in setup is
less than the number of channels in the Dolby Digital program, some
channel combining will be necessary to present the program on the
available number of channels/loudspeakers.
As a part of any program's production, its producers can set
and adjust the type and ratios allowed for downmixing
somewhat to ensure optimum results without compromising
the full Multichannel balance.This is accomplished by
including specific data within the Dolby Digital bitstream
which represents different mixing coefficients for the centre
and surround channel signals.
These will be detected by the SP1 and used to produce the
downmix if this mode is selected.

12. Music Modes

Pressing this button will illuminate the LED and sequentially select
one of the five available music decoding modes.The five options
are: Party, Natural, Stadium, Club, and DTS Music (see * page 21) .
NOTE: When you choose to listen to a DTS encoded music CD or music
video DVD or LD, please switch to the DTS Music setting and de-activate
any other settings such as THX processing as they are not needed.
Please see Appendix -- A for more details on each of these
proprietary music modes.
