Bridging (strapping)
For bridging into a single speaker load, the Orion XTR5001, XTR10001
and XTR15001 have the ability to be bridged with another amplifier of
the same model. To do this you must utilize the MASTER/COPY switch
settings. For the MASTER amplifier, set the switch setting to MASTER.
This will route the signal through RCA to the other (slave) amplifier.
On the Slave amplifier set this switch to the COPY position. Refer
to Line Output Configuration section of this manual. Set the PHASE
switch on the slave amp, move the phase switch from 0 to 180, exactly
opposite of the master amp. Refer to the Phase Switches section of
this manual.
On the slave amplifier be sure to turn off all crossovers. For the
speaker connections, connect the positive (+) speaker lead from the
speaker to the positive (+) speaker terminal of the master amplifier.
On the negative (-) speaker connection, take the negative (-) speaker
terminal of the master amplifier and connect it directly to the nega-
tive (-) speaker terminal of the slave amplifier. The remaining positive
(+) speaker terminal of the slave amplifier must be connected to the
negative (-) speaker lead from the speaker.
WARNING! The impedance of the speaker must not be less than 2Ω.
See diagram below.
NOTE: For best results, connect both negative speaker terminals on
the master amp to both negative terminals on the slave amp using at
least 12 AWG cable.
