Bridged Mode Connections
In general, it is recommended that the BRIDGED mode not be used in multi-room applications where several
speakers are driven through room volume controls and the like.
For such applications, use the STEREO mode. Use the BRIDGED mode for single speaker, higher power
applications, such as in surround sound systems. Use speakers with an impedance rating of 8-Ohms minimum.
To make connections for the BRIDGED mode, follow the steps given before for stereo connections, but with the
following differences:
1. You may connect the RCA-type patch cables from the OUTPUT jacks of the driving preamp or other source to
either the LEFT or the RIGHT input jacks of the bridged pair, as shown in Fig. 6. Do this for just the amplifier pairs
you wish to run in the bridged mode.
CAUTION: Be sure Power is OFF when connecting or switching the amp into or out of BRIDGED operation.
2. Slide the MODE switch to the BRIDGED position.
NOTE: Do this only on the amplifier pairs you wish to run in the bridged mode!
3. Connect one speaker wire pair between the 4-terminal "SPEAKER" connectors on the PA435X and the speakers
as shown in Fig. 6. Be sure to use only the two outer terminals marked "+” and "–" on the 4-terminal connector as
shown on the panel for BRIDGED connections.
NOTE: Only
one speaker is connected per amplifier pair in the BRIDGED mode!
