USER MANUAL • 12 • ADDITIONAL SURROUND & SETUP INFORMATION
Using the Blue Sky BMC MK III as a multi-channel volume control
There may be applications where the user wants to use the Blue Sky BMC
MK III only as a multi-channel volume control. The "6 CH VOLUME" preset can
be used for the this purpose. To active that preset go to the PRESET MENU,
by pressing the MENU button, press the up arrow (C) button until the display
reads "6 CH VOLUME" and then press the "+" (R) button.
6 CH VOLUME
LOAD PRESS +
PLEASE NOTE: This preset will defeat the bass-management and LFE low
pass filter and the +10dB LFE gain. As with all presets, any and all settings
can be altered from the factory starting point.
The LFE Channel
The LFE Channel was originally designed for film applications as a way to
increase the low frequency "head-room" (not extend the frequency response)
of the playback system. This additional headroom was created by adding
+10dB of in-band gain to the LFE channel. This channel should only be
used when no additional headroom is available in the other channels for
low frequency effects. As an example, you may use the LFE channel to
increase the dynamic low frequency content of a movie that has many large
explosions. This is rarely the case in music, although there may be some
creative reasons to use the LFE from time to time. It is important to note
that no "significant" audio should be sent exclusively to the LFE channel.
The reason for this is that if a Dolby Digital audio track is folded down to 2-
channels, which can happen if a consumer doesn't have a surround system,
the LFE channel will not be added to the fold-down mix (all other channels
will be added to the fold-down).
