QSC Audio CMX 2000V user manual Speakon Outputs, Speaker Cabling

Speakon™ Outputs

CMX amplifiers offer a choice of output connections, with two NL4MD Speakon™ jacks and a terminal block connector. (Figure 28 through Figure 30)

The Speakon™ connector is designed specially for high‑power speaker connections. It locks in place, prevents shock hazard, and assures the correct polarity.

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 Channel 2 output signals (Figure 29), so it is especially useful for PARALLEL INPUTS, bi‑amp, or BRIDGE MONO operation (see BRIDGE MONO operating precautions on page 9). Channel 2 Speakon™ carries only the output from Channel 2.

For easier insertion, use the newer‑style NL4FC Speakon™ connectors with quick‑lock thumb latches.

Speaker Cabling

Larger wire sizes and shorter lengths minimize both loss of power and degradation of damping factor. Do not place speaker cables next to input wiring.

WARNING: To prevent electric shock, do not operate the amplifier with any of the conductor of the speaker wire exposed.
