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
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.
