8. MULTIPLE M33 / R33 SYSTEMS

In multiple wireless system setups there must be an R33 receiver for each M33 transmitter used. Each M33/R33

combination must be on a different frequency. Simultaneous use of more than one M33 transmitter with a single

receiver will result in unsatisfactory system operation.

If two M33 transmitters are on the same frequency and are turned on at the same time, the R33 receiver will not

receive either of them properly. The weaker or most distant of the two transmitters will not be heard at all and the

stronger will have a steady, obnoxious whine in the background. Of course, use of two M33/R33 systems on the same

frequency at the same location creates an identical problem. Each M33 transmitter that is “on” must have a differ-

ent frequency.

Each M33 receiver can be hooked up with its own antenna

or can be stacked using the remote antenna connector.

Figure 7 shows three receivers using one antenna with the

remote antenna jacks coupled together using short

“stacking” banana plug cords. These are available from

your local electronics supply store or from

LECTROSONICS as part number MM-8. Up to five

receivers can be connected in this manner. When an

external antenna is used, it will be necessary to use an

Amphenol 83-1T (or equivalent) coaxial “T” connector in

order to connect to the second R33 with the MM-8 cord.

The “T” connectors and cables are commonly used with

CB (citizens band) radios and are available at stores such

as Radio Shack.
