...It is possible to minimise the occurrence of unwanted "splatty" noises by using diversity receivers, and these have been available for many years.  But many are not that small.  The most compact diversity receivers were at least the size of a large paperback book.  Before the Dx2000, diversity systems were the property of "serious" drama recordists, and those of us who do portable work only dreamed of the advantages.

The Audio Dx2000 system changed all that.  They were the  first UK company to introduce a miniature (cigarette pack sized) receiver system and many recordists here have grown to love and trust that range of equipment. The Matt black diversity Dx2000 is slightly smaller than two credit cards side by side and just 3/4" thick.

Operation is simplicity itself.  You don't need to bother with the on/off switch in most circumstances as the external power input on the six pin lemo connector can be shorted by your output cable, which then effectively turns the receiver on and off when you insert and remove the output lead - a useful time saver.

The RMS2000 series of radio mics have all been distinguished by their exceptionally clean sound, and these receivers are no exception,  the sound is possibly the cleanest of all the radio mics I've used in 12 years in the film industry.

The advantages of the diversity system really become apparent at medium to long range situations which are the times when you normally expect to hear the odd unwanted crackle or splat.  I recently had to reshoot some links in a warehouse due to a change in the script. I had used my old non-diversity receivers for the original shoot, and tried out the Dx2000 receivers on the reshoot day (using the same transmitters).  On the original shoot day I was occasionally worried by radio splats as the presenter walked in and out of the metal shelves and racks - nothing that couldn't be cured by the odd retake or piece of clever post production.  Not so for the reshoot.  The Dx2000s were faultless throughout the day and not once did I hear one of those all too worrying noises just before the word "Action" - which always puts me on edge until the take has been successfully put in the bag.

In conclusion, the Dx2000 receivers are easy to set up and use, and trouble free.  I just rig them and forget them, occasionally checking to see that my batteries are OK.  They're not cheap but the extra peace of mind is worth every penny in my bank.
