DOWN MIX CONFIGURATION
13
The Millennium 2.4.6 can be down-mixed to accommodate two to
six channel systems, using the System Configuration switches on
the back panel. The factory default position is for six channels. If
you are missing surround speakers or a center channel speaker,
the relevant audio information may be down-mixed into your main
left and right channels.
It is recommended, however, that the down mix configuration switches remain in their factory
default (up) position when employing the Millennium 2.4.6 in any 5.1 loudspeaker application. If
you are not using a Center channel loudspeaker, then you may try placing switch #2 in the down
position, which blends the center channel information into the Left and Right Front channels. It is
also possible to down mix the surround channel information into the main Left and Right Front
channels by placing switch #1 in the down position, but this effectively defeats the purpose and
intent of 5.1 music and movie surround program material.
Be extremely cautious down mixing the LFE .1 (extended Low Frequency Effects) channel.
Since almost all music mixes employ full frequency range program material on its primary chan-
nels, you can run the risk of generating excessive bass into the main Left and Front channels.
Do not put switch #3 in the down position unless you are confident your main Left and Right
loudspeakers can handle the additional bass information, regardless.
In the up (default) position switch #4 automatically prioritizes the coaxial input of the 2.4.6. To
prioritize the TOSLINK optical input, flip switch #4 to the down position.
Switches #5 and #6 control the pass-through functionality of the Millennium 2.4.6. Keeping both
switches in the up (default) position is considered ‘normal’ for installations where the 2.4.6 is
placed between the preamplifier and the amplifier. This provides automatic pass-through of all
analog channels when there is no DTS encoded signal present.
When using the 2.4.6 as a stand-alone DTS decoder/preamp, place switches #5 or #6 in their
down positions. This will disable the automatic pass-through feature for the analog signals, thus
eliminating the “click” of the pass-through relays when a DTS disc is played, skipped, or paused.
To selectively disable the pass-through feature in the Manual mode only, place switch #5 in the
up position and switch #6 in the down position. This configuration provides normal pass-through
and volume matching when in the Auto mode, yet silences any audible clicking when in the
Manual mode.
Follow the table below to configure playback of your DTS encoded source material for proper
playback in your system.
