PA324 Input and Output Connections
SPEAKER CONNECTION
Here are three ways in which speakers can be connected to the PA324: A single speaker can be connected to either the A or B jack of AMP 1 and AMP 2, two speakers can be connected in parallel to both the A and B jacks of AMP1 and AMP 2, or a single speaker can be connected to the BRIDGE jack (bridge connection). For each of these, the required speaker impedance will differ.
Refer to the following diagram, and make sure that the speaker impedance is not less than the specified value.
Additional, or alternative amplifiers can be connected to the MAIN OUT and MONITOR OUT jacks on the front panel.
When connecting one speaker to POWER AMP 1 and one speaker to POWER AMP 2, use speakers with a 4 – 8 ohm impedance rating.
When connecting two speakers to POWER AMP 1 and two speaker to POWER AMP 2, use speakers with a 8 – 16 ohm impedance rating.
When the POWER AMP S are in BRIDGE use a speakers with a 4 – 8 ohm impedance rating.
