These cables are available as accessories (see accessories listing).

4.If multiple wireless systems are being used, a multi-coupler will minimize antenna interference. A multi-coupler has one set of antennas and distributes RF signal to multiple systems. The Electro-Voice A/P4X4 will supply antenna signal and DC power to 4 systems, eliminating 3 exter- nal power supplies and 6 antennas (Figure 12).

COMPATIBILITY

The receiver and transmitter must be tuned to the same frequency in order to operate together as a system. Mixing brands of wireless components, even if units have the same frequency, will not work due to differences in companding circuits.

If two or more MS3000 and/or other VHF/UHF wire- less systems are being used in the same location, proper frequency coordination is necessary to avoid interference. Frequency mixing and spacing must be factored along with local TV stations to deter- mine if conflicts will result from a specific group.

Contact your dealer or Electro-Voice for frequency- selection assistance if you are planning to add more wireless systems to be operated simultaneously in the same location.

POTENTIAL SOURCES OF INTERFERENCE

There are many potential sources of interference for your wireless system. Any electronic component that contains digital circuitry including digital signal processors (reverb/multi-effects units), electronic keyboards, digital lighting controllers, CD players and computers all emit rf energy that can adversely affect the performance of your wireless system. It is always best to place your receiver as far away from these devices as possible to minimize this potential source of interference.
