The BMC MK II allows for two BMC MK II I/O units to be controlled by
a single remote. This allows for up to 10.2 calibrated & bass-managed
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 II 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 connections 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 1 or 2. For example
there is now a RIGHT 1 and a RIGHT 2.
CONNECTIONS AND WIRING
Because of the flexibility of a dual BMC MK II 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 MASTER I/O (Unit 1) to the AUX I/O
(Unit 2). 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.
Important notes for this type of setup:
1. SUBWOOFER GAIN 1 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 GAIN 2, in the CAL CHANNELS
menu.
3. The LFE Input on the MAIN unit (1), should be used for
connection to the LFE Channel. The LFE Input on the AUX I/O unit
(2), should be used as the LF input coming from the SUB out on the
MAIN (1) I/O unit.
4. To get the most electrical LF headroom, set both “SUB OFFSET
1 “and “SUB OFFSET 2” to -10dB. Then set the “LFE GAIN 2” to
+10dB.
5. The LFE GAIN 1 (main I/O) setting can be set to 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.
