Barrier Block

If the amplifi er is set for Stereo (Dual), connect the positive (+) and negative (–) leads of each loudspeaker to the appropriate Channel 1 and Channel 2 output connectors as shown in Figure 1.9.

If the amplifi er is set for

Bridge-Mono (if equipped),

connect a mono load across

the positive terminals of each

channel as shown in Figure 1.10. Do NOT use the nega- tive terminals when the amp

is set for Bridge Output.

If the amplifi er is set for Parallel-Mono (if equipped), connect 14-guage or larger jumper between the Channel 1 and Channel 2 Positive terminals, then connect a mono load to the Channel 1 positive and negative terminals as shown in Figure 1.11. Do NOT use the Channel 2 terminals when the amp is set for Parallel Output. Caution: Never

short or parallel the output channels of an amplifier to itself or to any other amplifier.

Output Wiring Tips

1.To prevent possible short circuits, wrap or otherwise insulate exposed loudspeaker cable or cable connectors.

2.Do not use connectors that might accidentally tie conductors together when making or breaking the connec- tion (for example, a standard, 1/4-inch stereo phone plug).

3.Never use connectors that could

be plugged into AC power sockets. Accidental AC input will be an electri- fying experience for your equipment. But you will find out real quick if your speakers are any good at 60 Hz!

4.Avoid using connectors with low cur- rent-carrying capacity, such as XLRs.

5.Do not use connectors that have any tendency to short.

Neutrik® Speakon®

To assemble the Neutrik Speakon NL4FC connector, complete the following steps:

1.Slide the bushing (E) and chuck (D) onto the end of the cable as shown in Figure 1.12.

Note: Your NL4FC connector kit should contain both a black and a white chuck. Use the white chuck for cable with a diam- eter of 0.25 to 0.5 inch (6.35 to 12.7 mm). Use the black chuck for cable with a diameter of 0.375 to 0.625 inch (9.525 to 15.875 mm).

2.Strip approximately 3/4-inch (20-mm) of casing from the cable end. Strip approximately 3/8-inch (8-mm) from the end of each of the conductors down to bare wire (C).

3a.Insert each wire into the top of appropriate slot of the connec- tor insert (B) as shown in Figure 1.13. Use a (1.5-mm) allen wrench or flat blade screwdriver to tighten the side connecting screws.
