Speaker Connections; Bridging - Orion HCCA-D1200 Owner's Manual

Speaker Connections

The Orion HCCA-D1200, HCCA-D2400, and HCCA-D5000 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. See diagrams below.

Bridging

For bridging into a single speaker load, the Orion HCCA-D1200 and HCCA-D2400 have the
ability to be bridged with another amplifier of the same model. To do this you must utilize
the MASTER/SLAVE switch settings. For the MASTER amplifier, set the switch setting to MAS-
TER. This will route the signal through RCA to the other (slave) amplifier. On the Slave
amplifier set this switch to the SLAVE position. Refer to Auxiliary Output Configuration sec-
tion of this guide. 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. 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.
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.
