Speakon Outputs<br />

<strong>CMX</strong> amplifiers offer a choice of output connections, with two NL4MD Speakon jacks and a terminal block connector. (Figure 28 through Figure<br />

30)<br />

The Speakon connector is designed specially for high-power speaker connections. It locks in place, prevents shock hazard, and assures the<br />

correct polarity.<br />

Each channel accepts a normal two-wire cable. In addition, Channel 1 accepts a four-wire cable. Channel 1 Speakon jack has both Channel 1 and<br />

Channel 2 output signals (Figure 29), so it is especially useful for PARALLEL INPUTS, bi-amp, or BRIDGE MONO operation (see BRIDGE MONO<br />

operating precautions on page 9). Channel 2 Speakon carries only the output from Channel 2.<br />

For easier insertion, use the newer-style NL4FC Speakon connectors with quick-lock thumb latches.<br />

Speaker Cabling<br />

Larger wire sizes and shorter lengths minimize both loss of power and degradation of damping factor. Do not place speaker cables next to<br />

input wiring.<br />

WRRNRNG: To prevent electric shock, do not operate the amplifier with any of the conductor of the speaker wire exposed.<br />
