WIRING THE SYSTEM

IMPORTANT: Make sure all equipment is turned off before making any connections.

For speaker connections, use a high-quality speaker wire with polarity coding. The side of the wire with a ridge or other coding is usually considered positive polarity (i.e., +). Heavier-gauge wire should be used when more than 50 feet (15m) of speaker wire is required.The wire channels on the rear of the Beta ES250 will accommodate most types of 14- to 18-gauge wire.

NOTE: If desired, consult your local Infinity dealer about speaker wire and connection options.

To ensure proper polarity, connect each + terminal on the back of the amplifier or receiver to the respective + (red) terminal on each speaker, as shown in Figure 8. Connect the – (black) terminals in a similar way. See the owner’s guides that were included with your amplifier or receiver to confirm connection procedures.

IMPORTANT: Do not reverse polarities (i.e., + to – or – to +) when making connections. Doing so will cause poor imaging and diminished bass response.

Figure 7. This example shows how to connect bare wires to the terminals.
