Infinity CAS 3.1, CAS 2.1 manual Bi-Wiring, Single-Stereo Amplifier

BI-WIRING

The CAS speaker’s connection panel and internal dividing network are designed so that separate sets of speaker cables can be attached to the low-frequency transducer and midrange/high-frequency transducer portions of this dividing network.

This is called bi-wiring. Bi-wiring can provide several sonic advantages and considerably more flexibility in power amplifier selection.

1.Remove strapping wires.

2.Insert the speaker wire for the high frequencies into the (HF+) and (HF–) terminals and tighten.

3.Insert the speaker wire for the low frequencies into the (LF+) and (LF–) set of terminals and tighten.

Dual-Stereo Amplifier

One amplifier drives the low-frequency sections of both speakers. A second amplifier drives the mid/high-frequency sections of both speakers.
