GENERAL DESCRIPTION
MCR42 is a camera dual true diversity wireless-microphone receiver system in a modular stand-alone or slot-in
configuration (compatible with most camera’s slot).
Þ camera “slot-in” receiver (for Ikegamy, Philips, Sony cameras)
Þ camera “stand-alone” very small dual true-diversity receiver,
powered by 5 ÷ 18 Vdc external source
All audio processing is managed by a powerful DSP to allow multicompanding, audio enhancement and a digital
control data.
Very easy and versatile thanks to its:
Oled display,
navigation button controls,
infrared sinc and programming,
automatic scan.

1 multicolour RGB LEDs to easy indicate Rx1 & Rx2 power status:
- GREEN/PALE GREEN if "Receivers ON" with external power supply/battery;
- GREEN blinking/PALE GREEN blinking if low power supply/ low battery level
- RED blinking indicates power supply status of transmitter:
·
slow blinking, at 25% battery capacity;
·
fast blinking, at 12.5% battery capacity.
2 multicolour RGB LEDs to easy indicates Rx1 & Rx2 RF status. Always 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 B (blue) is active;
- YELLOW, if signal above squelch and both antenna are used.
2 multicolour 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.
