Cable Considerations
Be sure to use the proper cable for connecting the matrix to the customer lanes. For audio it is HIGHLY
RECOMMENDED to use Hamilton cable (E0680) for distances up to approximately 180 feet. This
cable contains a 16AWG twisted pair for the speaker, a 20AWG twisted pair for the call button and a
20AWG twisted, shielded pair for the microphone. For distances over 180 feet it may be necessary to
use a heavier gauge of wire for the speaker to prevent excessive loss due to the wire resistance.
If you don't use E0680 cable, make sure the microphone pair is individually shielded with it's own
drain wire. DO NOT use cable with an overall shield. DO NOT use cable with individually shielded
pairs that has a common drain wire. If your cable has individually shielded pairs, with each pair having
it's own drain wire, only connect the drain wire for the microphone pair.
Another option for audio is to use Category 5 cable (5E & 6 are also acceptable) for distances up to
1000 feet. Using this type of cable requires the Cat 5 Lane Speaker Driver Kit (E0958-KIT). 110VAC
must also be available at the lane. This kit can also be used to extend the length of standard E0680 audio
cable to a maximum of 1000 feet. See the section "Cat 5 Lane Speaker/Driver Kit Installation" for more
information.
For video applications use 75 ohm coax cable designed for CCTV applications. Belden 1426A is a very
good cable to use for reference. It has a solid copper center conductor and a copper braid providing 95%
shielding. Another option for video is to use twisted pair cable with video baluns. The specifications of
the video balun manufacturer must be followed as to the category of cable that is acceptable and whether
power is required.
Matrix Installation
Mount the audio (and video) matrix in an accessible but out of the way location near where the consoles
will be located. Figure 1 shows two mounting methods for all but the 5003 audio matrix which has a
small plastic enclosure with mounting tabs.
