MAIN FEATURES
Two channels diversity receiver
DSP analogue Output (AES3)
Up to 790 MHz bandwidth in 470/1260 MHz range
Next Gen Multiband front-end filtering:
oHigh Q moving filter in 470-960 MHz
oHigh Q moving filter in 960-1160 MHz (DME)
oCountry specific saw filters:
USA 940-960 MHz &
Japan 1240-1260 MHz or 806-810MHz
Wideband and Narrowband DSP-FM operation (SW selectable):
oNarrowband allows more 50% band efficiency
oNarrowband allows about 3dB extra sensitivity and noise immunity
Extreme low noise VCO with ultrafast spectrum scan for optimal quick & easy setup
High contrast OLED display
Automatic scan & transmitter programming through infrared
DSP based for extreme flexibility and multi-companding operations
Miniature design with integrated battery pack:
- rechargeable lithium pack
- 2 x AA batteries
Operation and charger (lithium) thru USB connector
Monitor & control through USB and Wisycom Manager 2.0 (computer SW):
oThis transform MPR52 in a quick and low noise portable spectrum scanner
Please note that the two channels, in order to protect them from
potential interferences coming from having the ultra-wide band, must use frequencies included
into a 30 MHz filter range.

SAFETY INSTRUCTION
Read this safety instruction and the manual first
Follow all instructions and information.
Do not lose this manual.
Do not use this apparatus under the rain or near the water.
Do not install the apparatus near heaters or in hot environments, do not use outside the
operating temperature range.
Do not open the apparatus, only qualified service technician are enabled to operate on it. The
apparatus needs servicing when it is not properly working or is damaged by liquids, moisture or
other objects are fallen in the apparatus.
Use only accessories or replacement parts authorized or specified by the manufacturer.
Clean the apparatus only with dry cloths, do not use liquids.
Report the serial number and the purchasing date in front of the manual. It is needed to have
proper replacement parts or accessories from the manufacturer.
When replacement parts are needed, use only replacement parts authorized from the
manufacturer. Substitution with not authorized parts could result in electric shock, hazards or
fire.
Keep attention on all the labels with warnings or hazards on the apparatus.
The apparatus is intended for professional use; anyway the manufacturer alerts the user
that the headphone output power of the apparatus could exceed the level of 85 dB(A) of sound
pressure level and this could be dangerous for the hearings. Do not use the headphone with high
power level or for long time. Reduce the power or suspend the hearing in case of any kind of hearing
problem.
BATTERIES
MPR52-ENG works with standard camera battery:
-2xIEC-LR6 1.5 size-AA alkaline or NiMh rechargeable
-KLIC 8000 (lithium-ion, rechargeable)
-DB50 (lithium-ion, rechargeable)
-DR9708 Duracell (lithium-ion, rechargeable)
Battery status can be checked on OLED display or looking the status of LED indicator ON.
Charging of lithium-ion rechargeable batteries can be done with

A. dedicated charger
B. thru the integrated micro-usb-B connector
C. thru ACM50 battery charger
We don't recommend to use the device during the batteries charging with lithium-ion
rechargeable batteries inside. Don’t use the receiver without batteries . The receiver powered thru
micro-USB or mini-XLR connector without batteries doesn't work correctly.
DO NOT operate the device with some new and some old batteries. Always replace ALL
BATTERIES.
Remember to remove the batteries when the device is not in use.
