panel. The CM16a uses terminal block

 

 

connectors for the audio inputs. They are

 

 

sometimes called “Phoenix” or

 

 

“Euro”connectors. These connectors al-

 

 

low the installer to pre-wire the input ter-

 

 

minations before the CM16a is installed in

 

 

the rack. It also allows for re-routing of

 

 

audio inputs by simply interchanging connector locations without the need for any

 

tools. See Appendix (page 38) for connector manufacturer’s part number reference.

BALANCED INPUT CONNECTION

Balanced connection is recommended for all inputs.

The illustrations to the right show the proper connection of audio program input sources for both balanced and unbalanced inputs.Use balanced connections when- ever possible. If unbalanced audio sources are used, it is preferable to use an appropriate audio transformer (or other unbalanced-to-balanced “converter”) to provide a balanced input to the CM16a. If this is not possible, then it is recommended the negative terminal and shield terminal be connected to one another with a jumper wire.

Terminal Block Connector Hints-

Strip length : 6 to 8 mm ( 1/4 to 5/16 inch) .

Be careful not to nick or cut the conductor strands .

After each conductor has been stripped, insert it fully into the connector and tighten the retaining screw. When stranded wire is used, carefully twist the conductor strands together so when they are inserted into the connector assembly, no loose strands short adjacent terminals.

UNBALANCED INPUT CONNECTION

STRAIN RELIEF

For heavy-duty input cables, the use of connectors with integral strain relief is recommended. These connectors have a large plastic tab molded as part of the assembly which provides an area to tape or tie-wrap the cable to. At the time of this writing, only the 3-pin with the strain relief was available through QSC . See Section 6 (Appendix) for connector part numbers.
