The BMC MK III allows for two BMC MK III I/O units to be controlled
by a single remote. This allows for up to 10.2 calibrated & bass-man-
aged channels, to be controlled from a single master gain control.
IMPORTANT: The BMC remote connects to each I/O unit via the included 6
conductor phone cable. It is important that you clearly label the I/O units,
along with the cables. This is because you must connect the BMC MK III I/O
units to the remote's MAIN and AUX inputs the same way, each time they are
connected. This is because calibration information is stored in each I/O unit
and if you accidentally swap I/O units, as it relates to the MAIN and AUX con-
nections on the remote, you will need to redo some or all system settings.
If you are adding a second I/O unit to an existing single I/O unit system.
Make sure to connect the second I/O unit to the AUX connector on the
remote. Settings for the MAIN I/O unit will not be corrupted and will be
saved in memory.
Once two units are connected, calibration settings are now available for all
12 channels and each channel is marked with a MAIN or AUX. For example
there is now a RIGHT MAIN and a RIGHT AUX.
CONNECTIONS AND WIRING
Because of the flexibility of a dual BMC MK III I/O system, it is difficult to
detail every possibility, with regard to system configurations. However there
are some basic rules and general guidelines which are detailed below.
SYSTEM CONFIGURATIONS
"X.1" System Setup: This setup applies to any system with two I/O units,
where the bass is being routed from the MAIN I/O (MAIN) to the AUX I/O
(AUX). This can be any system beyond 5.1 and all the way up to 10.1. The
general overview, with regard to connections and setup is shown on page
17.

USER MANUAL • 13 • DUAL BMC MK III I/O UNIT SETUP
Important notes for this type of setup:
1. SUBWOOFER MAIN GAIN should be set to 0dB, in the CAL
CHANNELS menu.
2. Overall system subwoofer level should be set on the BMC I/O
unit connected to the AUX connector on the remote. This channel
will be marked SUBWOOFER AUX GAIN, in the CAL CHANNELS
menu.
3. The LFE Input on the MAIN unit, should be used for connection
to the LFE Channel. The LFE Input on the AUX I/O unit (AUX),
should be used as the LF input coming from the SUB out on the
MAIN I/O unit.
4. To get the most electrical LF headroom, set both "SUB
OFFSET MAIN "and "SUB OFFSET AUX" to -10dB. Then set the
"LFE GAIN 2" to +10dB.
5. The LFE MAIN GAIN (main I/O unit) setting can be set to
either +10 or 0dB, depending on the format being used (Dolby
recommends +10dB for Dolby Digital).
"X.2" System Setup: This setup applies to any system with two I/O units,
where the bass for each I/O unit is being routed directly to a subwoofer.
This setup requires a minimum of two subwoofer. This can be any system all
the way up to 10.2 channels. Because there are no accepted standards for
this type of configuration, we have no specific recommendations. However,
all settings which were available in a 5.1 system are now also available for
up to 10.2 channels and can be configured to your liking.
