Mixed mono operation using a 400 BDG Bridging Module is the approach to
use when you want to add a subwoofer to the a single amplifier system. This
mode can be used to provide more power to the subwoofer while maintaining
stereo left and right. In this system, the 400 BDG Bridging Module accepts
the stereo inputs and turns one channel over 180 degrees (inverts the channel).
Both channel outputs of the amplifier are now connected to the subwoofer
with the inverted channel being used as the
negative
input. This works be¬
cause the two channels are 180 degrees out-of-phase.
A REMINDER: The speakers must never be grounded to tho car chamits or
body. To do so will cause severe noise problems and, in the case of bridging,
cancel out the two phase operation.

DIN CONNECTOR
All ORION Accessorial anil
Amplifiers have this DIN
configuration.
The left mid/high speaker is connected
normally,
but the connections to the
right mid/high speaker must be turned
over
to retain the stereo effect. This
means that the yellow lead now becomes the negative lead and the black/
yellow lead becomes the positive lead.
'Phantom Power' (+15V & -15V) is supplied to dll
ORION accessory modules by the amplifier through th«
DIN cable. (When ORION amplifiers are not UMd,
ORION PPS 100 Phantom Power Supply is requimd )
