Bridging (strapping)

For bridging into a single speaker load, this amplifier has the ability to be bridged with
another amplifier (must be the same model). To do this you must utilize the MASTER/SLAVE
and PHASE switch settings. On the master amplifier, set the switch setting to MASTER. The
signal is then routed through RCA Line Out to the RCA Line In on the other (slave) amplifi-
er. The slave amplifier must have the MASTER/SLAVE switch set to the SLAVE position. On
the master amplifier make sure the PHASE swtich is set to the 0 position (factory default).
On the slave amplifier set the PHASE switch 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 the Intelli-Bass control to 0 (zero). 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 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 1W.
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.

AMPLIFIER INSTALLATION

Choosing Mounting Locations

The location of your amplifier will depend on several important issues. Due to the low pro-
file size of the Orion amplifiers, there are many possible installation locations that will yield
satisfactory amplifier performance. Always mount the amplifier in a place that protects the
amplifier from the elements. In addition, mount the amplifier on a stable, flat surface.
