Speaker connections

One or more speakers (4, 8 or 16 Ohm) speakers can be connected
to the amplifier with or without transformers. However, before you
connect any speakers to the amplifier, the total speaker impedance
must be calculated in order to avoid damage to the amplifier. A total
speaker impedance greater than 16 Ohms or less than 4 Ohms can
cause this damage to occur.
To begin with, in order to ensure equal volume from each speaker,
all connected speaker should have the same impedance.
A proper total
achieved by combing series and parallel speaker connections. Please
see the diagram which follow which explain how to accomplish this.
Finally always use the shortest length of speaker wire possible of
proper gauge. Usually 18 gauge wire is adequate for lengths under
25 feet, while 16 gauge is used for greater lengths.

Connector options

The PA305 offers several different connection points for speaker
hookups. These include screw terminals, a 6. 3mm jack, and a pair
of banana plug connectors.
It is not proper or recommended to connect all the speaker outputs
simultaneously. In addition, please note that when the 6. 3mm jack
is used, all the screw terminal and RCA signal outputs are
disconnected.
