MPR30-ENG core is a power digital audio processor
that, besides an unbeatable audio quality and
flexibility, can emulate most companders systems on
the market. On this menu you can setup the audio
companding chipset emulation. ENR is emulating the
Philips™ SA572 and PTT digital data of Wisycom
transmitters. Other setups can be loaded on request.
Tone squelch ON: when the tone squelch is enabled
the audio is muted unless the correct carrier is
detected. Tone squelch allows working with lower RF
squelch, increasing the coverage and the robustness
especially in presence of digital television carriers
(DVB-T).
Tone squelch OFF: the audio is muted if RF level <
Squelch level
It is possible to set the nominal audio from +18dBu
(peak deviation) and -35 dBu:
LINE: -5 dBu ÷+18 dBu (1 dB step)
MIC: -35 dBu ÷-12 dBu(1 dB step)
To change audio phase of 0 deg or 180 deg.
This function can be called also using the dedicated
DOWN/UP button (push and keep). It allows making
a scan over a desired frequency group.
MPR30-ENG manages up to 2400 custom frequencies
organized in 40 groups of 60 channels each. This
extreme flexibility makes the scan function very
flexible.
