Connecting A Passive (Non-Powered); Subwoofer; Connecting Dual Dynamo Iw Subwoofers - MartinLogan MP500 Operating Manual

2.3 CONNECTING A PASSIVE
(NON-POWERED) SUBWOOFER
This mode only supports subwoofers rated at 8 Ohms or
higher. Bridged Mode increases the amplifier power available
for a single speaker. This function is designed for passive
subwoofers that require external amplification and can be
enabled using the below method:
1. Remove the Euroblock connector from the MP500 by
gently pulling it until it releases.
2. Use a small slotted screwdriver to loosen and tighten each
contact on the Euroblock when inserting the speaker wire.
3. Connect the red (+) connection of the subwoofer to
the positive (Bridge Mode +) contact on the Euroblock
connector as indicated by the printing located on the
MP500 (below the connector).
4. Connect the black (–) connection of the subwoofer to
the negative (Bridge Mode -) contact on the Euroblock
connector as indicated by the printing located on the
MP500 (below the connector).
5. After attaching subwoofer wires to the Euroblock connector,
insert it into the MP500 by gently pressing it into place.
2.4 CONNECTING DUAL DYNAMO IW
SUBWOOFERS
For maximum performance, MartinLogan recommends using
an MP500 for each subwoofer in the system. When running
2 subwoofers from a single amplifier is required, the MP500
can drive dual subs in a "bridged parrallel" configuration.
Note: This configuration is only recommended with
MartinLogan Dynamo IW subwoofers and you must use
the "Dual Subwoofer DSP Preset Profiles" as outlined in
the DSP Profile Section.
1. Remove the Euroblock connector from the MP500 by gen-
tly pulling it until it releases.
2. Use a small slotted screwdriver to loosen and tighten each
contact on the Euroblock when inserting the speaker wire.
3. Connect the red (+) connection of each subwoofer to
the positive (Bridge Mode +) contact on the Euroblock
connector as indicated by the printing located on the
MP500 (below the connector).
4. Connect the black (-) connection of each subwoofer to
the negative (Bridge Mode -) contact on the Euroblock
connector as indicated by the printing located on the
MP500 (below the connector).
5. After attaching subwoofer wires to the Euroblock connector,
insert it into the MP500 by gently pressing it into place.
