Squelch
field strength: with externally adjustable threshold and adaptive-mode working (the receiver adapts itself to the differensituations of medium signal-strength levels and fading speeds).
tone-squelch: with decoding of the matching sub-carrier, digitally modulated, generated by the relevant transmitter. This function can be switched-off for the compatibility with other brand TXs.
Squelch-controlled
is controlled by the squelch circuit. When the AF output line is active, DC output-power the DC input-power is connected to pin 2 of the XLR4-M-DC input-connector on rear panel (max current = 2A).
“Noise Reduction” system
compander circuit, can be internally pre-set (or switched off) to:
ENR (Wisycom Extended-NR).
NR (standard-NR), to be compatible with other systems.
AF line output
transformer balanced, floating • Output impedance = < 50 ohm.
AF output level
+10 dBu (2450 mVrms), @ ±40 KHz deviation.
AF bandwidth
20 Hz ÷ 20 KHz.
Frequency response
< ±0.5 dB (±0.2 dB typ.) in the 30 Hz ÷ 20 KHz range.
Distortion
< 0.3 % (0.15 % typ.) @±40 KHz deviation (< 0.5 % @ peak deviation).

Diversity technology
true-diversity (Twin receiver circuits, with high-speed and low-noise electronic switching).
Remote diversity function
the MSR916 receiver, along with audio signal on the line-output, is signalling also the RSSI level. A Centralized Automatic Selector (i.e.: RDA41, suitable for 4 remote receivers) can use this voting information to use in any time select the best audio signal.
