OMD-28
The OMD-28 is equipped with 3 sets of binding posts
which allows the speakers to be tri-wired/tri-amped.
The tweeter's terminals are on top, the midrange
driver’s terminals are in the middle and the woofer's
terminals are at the bottom. Gold plated shorting
straps are factory pre-installed, one strap to connect
the three negative and one strap to connect the three
positive terminals.
NOTE: BOTH STRAPS MUST BE INSTALLED IN ORDER
TO USE THE TRADITIONAL CONNECTION METHOD
In order to bi-wire the OMD-28s, the metal straps can
simply be used to bridge two sets of binding posts
(instead of three) by moving the straps up or down. To
do so, loosen all of the connectors, pull the straps
away from the binding posts and reinstall the straps to
connect two of the three binding posts. Under normal
circumstances, the gold straps should be connected to
the middle and top set of binding posts. This way one
separate set of cables would be used to drive the two
8” drivers and the other cable would drive the
midrange and tweeter.
TRI-WIRE METHOD
(OMD-28 ONLY)
In order to tri-wire the OMD-28s, simply remove the
binding post straps from the speakers, and connect
three separate set of wires to the six binding posts.
Please ensure that polarity is maintained when
connecting the speaker wires.
BI-AMPLIFICATION /
TRI-AMPLIFICATION
The OM Design series can also be connected to
multiple amplifiers. Two or even three amplifiers in the
case of the OMD-28 can further enhance the
performance of the OM Design series. However,
choosing quality electronics is a crucial part in
achieving the full benefit of bi-amping/tri-amping.
Please consult your authorized Mirage dealer for
recommendations on adequate electronics. Please
follow the same steps as described in the section
above. Instead of connecting two sets of wires to one
amplifier, simply connect one set of speaker wires to
each amplifier.
