Radio Microphone Receiver Pilot Tone Detection Configuration

The Receiver is supplied with pilot tone detection enabled as standard. This means that announcements
from Radio Microphone Transmitters that do not provide the required pilot tone will be blocked

2

. The pilot

tone detection can be disabled in order to allow announcements from non-tone locked transmitters, and the
squelch level can be adjusted in order to minimise the interference of in-band signals although this should
not be necessary with the pilot tone detection enabled.

The pilot tone detection is enabled or disabled by DIP switch 1 on the microphone PCB (see

Figure 22,

page

32

), with the future option of setting it via the Router configuration; see

Table 3

.

The squelch level is adjusted as described in Section “

5.3 Radio Microphone Receiver Squelch Level

Configuration

” (page

35

).

Pilot tone detection enabled.
This is the factory default setting, for secure use with
the ASL RPA01 Radio Microphone Transmitters.

For future use.
This switch position will be used to set the pilot tone
detection, the squelch level, and the frequency
selection to be controlled through the Router
configuration.

Announcements from non-tone locked transmitters are completely blocked with Radio Microphone Receiver modules of Build
Standard (BS) 2B or later. With earlier Build Standards of Radio Microphone Receiver module the audio from non-tone locked
transmitters is muted but they can still make chimes and silent routes. These silent routes can be blocked as detailed in ASL
Technical Note 39; please refer to Application Solutions (Safety and Security) Limited for further details.
