NL4 Outputs
CMXa amplifi ers offer a choice of output connections, with two NL4 jacks and a
Terminal Block connector.
The NL4 connector is designed specially for high-power speaker connections. It
locks in place, prevents shock hazard, and assures the correct polarity.
The upper NL4 jack has both Channel 1 and Channel 2 outputs, so it is especially
useful for Parallel, bi-amp, or Bridge Mono mode operation (see Bridge Mono
mode operating precautions on
from Channel 2.
For easier insertion, use the NL4FC connectors with quick-lock thumb latches (Not
shown).
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
amplifi er with any of the conductor portion of the speaker
wire exposed.
Terminal Block Connector
The terminal block connector requires the following assembly.
1. Strip the wires to 7 ~ 8 mm.
2. Insert the wires into the male part of the connector according to the Mode you
are using. See below.
3. Use a fl at-tip screwdriver to secure the wires. Tighten the screws to 6 in.-lbs.
4. Insert the plug into the receptacle on the amplifi er.
5. Use a fl at-tip screwdriver to secure the connector. Tighten the screws to 6 in.-lbs.
