CONNECTIONS: OUTPUTS

OUTPUTS: PL2A amplifiers offer a choice of output connections; Neutrik NL4MD Speakon jacks and "touch-proof" binding post outputs.

SPEAKER CABLING: Always use the largest wire size and shortest length of wire practical for any given installation. Larger wire sizes and shorter lengths minimize power loss and degradation of damping factor. Do not place speaker cables next to input wiring.

BRIDGED-MONO PRECAUTIONS:

Do Not Use 2 Ohm Loads in Bridge Mono Mode! 4 Ohms is the minimum impedance for bridge mono operation!

This mode puts a high demand on the amplifier and speaker. Excessive clipping may cause protective muting or speaker damage.

Ensure the speaker has a sufficient power rating.

Output voltages greater than 100 volts rms are available between the amplifier's bridged terminals. CLASS 3 wiring methods, as specified in accordance with national (NEC) and local codes, must be used to connect the speaker. To prevent electric shock, do not operate the amplifier with any conductors of the speaker cable exposed.

Speakon™ Outputs: The Speakon connector is designed specially for high-power speaker connections. It locks in place, prevents shock hazard, and assures the correct polarity. For easier insertion, use the newer-style NL4FC Speakon connectors with quick lock thumb latches.

The upper Speakon jack (CH1) has both Channel 1 and Channel 2 outputs, so it is especially useful for parallel, bi-amp, or bridged mono operation. The other Speakon carries only Channel 2’s output. See the illustrations below.
