Speakon™ Outputs; Speaker Cabling - QSC CMX2000V User Manual

Speakon™ Outputs
CMX amplifiers offer a choice of output connections, with two NL4MD Speakon™ jacks and a terminal block connector.
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
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.
WRRNRNG: To prevent electric shock, do not operate the amplifier with any of the conductor of the speaker wire exposed.
