Preparing Your Receiver

Connecting Speakers

Preparing the Speaker Wires

Follow these guidelines when you select and connect speakers.

•Only connect speakers that are rated at between 8 and 16 Ohms.

•Be sure you properly connect all speakers.

•Do not connect two pairs of speakers to a single set of terminals (A or B) at the same time. When you use two pairs of speakers, connect one set to

Speakers A and one set to Speakers B.

•Realistic, Optimus, and other high- quality speakers have color-coded speaker terminals (red for positive polarity and black for negative polar- ity). Use these color-coded terminals as a guide to help you properly con- nect the speakers to the receiver.

•Use 16-gauge (or larger) speaker wire for all speaker connections, and con- sider possible speaker locations before you decide how much speaker wire you need.

Speaker wire consists of two conductors (individual wires) encased in insulation and is usually color-coded or marked with a ridge along one side so you can identify each conductor. Use these markings as a guide to help you properly connect the speakers to your receiver.

Follow these steps to prepare the speaker wires.
