• Noise Reduction system : DSP multi-compander emulation:
⇒ ENR (Wisycom Extended-NR)
⇒ Others, compatible with most existing systems,
thru an internal DSP emulation of SA572, SA575 and
Rms envelope compander chipset, fully user programmable
• AF bandwidth

• SND/D ratio (Analogue) : 110 dB typical [2]
• SND/D ratio (AES3)
: >125 dB typical [2]
• POWER LEDs
: 2 multicolor RGB LEDs to easy indicate Rx1 & Rx2 power status:
- GREEN, if "Receiver ON" with external power supply;
- RED, if Empty battery/power supply;
LEDs blinking indicates power supply status of transmitter:
- slow blinking, at 25% battery capacity;
- fast blinking, at 12.5% battery capacity.
• RF LEDs : 2 multicolor RGB LEDs to easy indicates Rx1 & Rx2 RF status.
Allways on in normal operation:
- RED, if both receivers RF level is under squelch level;
- GREEN, if signal above squelch level & antenna A (green) is active;
- BLUE, if signal above squelch level & antenna A (blue) is active;
- YELLOW, if signal above squelch and both antenna are used.
• AUDIO LEDs : 2 multicolor RGB LEDs to easy indicates Rx1 & Rx2 audio status:
- RED, if audio is muted cause of squelch (or tone squelch if active);
- GREEN, if audio is active and tone squelch present;
- BLUE, if audio is active and tone squelch not present.
• Front buttons
: simple operation with 4 buttons to quickly monitor and setup the receiver. One touch function for a frequency scan and sync function.
• Powering

Analogue Audio Output
• Audio line-output 1 & 2 :
• Audio line-output level :
• Audio line-output imped. :
electronically balanced on two 3 pin mini-XLR Female connector
Adjustable in a one dB step between:
-20 and +6 dBu (nominal) and MAX +12 dBu (peak deviation)
≤ 200 ohm.
To be properly used, the “basic” MCR 42
receiver has to be integrated with relevant
accessories (interchangeable by screws):
⇒ “Slot-in” execution
with SLK 42-xx rear-panel
suitable for the camera in use;
⇒ “Stand-alone” execution
with BPA 42/BPA 42 PTT rear-panel
with connecting cables for external feeding
and AF output connection.
The “slot-in” and “stand-alone” rear-panels
are connector-and screw-fitted into the receiver.
Consequently it is very simple to transform the
receiver from one execution to the other also
directly on the set.
