Speaker Connections; Bridging - Orion 12000 Owner's Manual

Speaker Connections

The Orion 300D, 600D, 1200D, and 2500D amplifiers offer two positive and two negative
output terminals for ease of connecting the speakers to the amplifier. Since these are mono
amplifiers, the speaker connectors are paralleled internally. Each amplifier is stable to 1W.

Bridging

For bridging into a single speaker load, the Orion 600D and 1200D have the ability to be
bridged with another amplifier of the same model. To do this you must utilize the
COPY/GAIN/MASTER switch settings. For the MASTER amplifier, set the switch setting to
MASTER. This will route the signal through RCA to the other (slave) amplifier. Refer to
Auxiliary Output Configuration section of this guide. To 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 guide.
On the (slave) amplifier be sure to turn off all crossovers. For the speaker connections, con-
nect 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 negative (-) 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. The impedance of the
speaker must not exceed 2W.
NOTE: There is no Copy/Gain/Master switch on the 300D.
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.
WARNING! The Orion 2500D is not designed to work in a bridged or strapped configu-
ration. Attempting to apply these configurations will damage the amplifier
and will not be covered under warranty.
