Speaker - Amplfier connection.
The speaker has two input/output connections. A maximum of two speakers should be connected to the PAC390.
1. INPUT jack (1/4 inch phone jack)
Connect the speaker to the amplifier unit using the supplied speaker cable. When separation of the speaker from the amplifier unit is needed, use cable with phone plugs.
2. Speaker wire connectors
Lets you connect the speaker to the amplifier unit or the second speaker using speaker wire.
Note: The wire gauge (thickness of wire) needed depends on the length of the wire. Use heavier gauge (16 gauge) for runs of about 30-50 feet. Use light gauge (18 gauge, lamp cord) for shorter runs.
