BRIEF DESCRIPTION

MPR30-ENG is a compact true diversity receiver designed for professional ENG, broadcast, and

field production applications. This receiver features a real TRUE DIVERSITY configuration along

with a unique wide-band tuning range up to 232 MHz.

A double stages input filters assure an excellent selectivity even in broad-band operations.

All audio processing is managed by a powerful DSP allowing:

- multicompanding,

- audio enhancement

- digital control data.

It is very easy and versatile thanks to its:

 Oled display,

 navigation button controls,

 infrared interface (for sync and remote configuration),

 micro-usb interface (for remote configuration and battery recharge),

 automatic scan.

MPR30-ENG is designed to be:

 “easy & quick to use” thanks to

o automatic setup functions (i.e. frequencies, scan for best channels),

o remote configuration utilities (thru infrared or USB interface) using Wisycom ENG

RX Manager application

o OLED display with intuitive context menu navigation

 “extremely flexible”, with an incredible frequency agility up to 232MHz

o MPR30-ENG-L: 470/700 MHz (TV ch 21/49)

o MPR30-ENG-H:566/798 MHz (TV ch 33/61)

 “best in class performances”, thanks to the latest Wisycom technology the unit has

extreme RF sensitivity and immunity and superb audio quality

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.

Other setups can be loaded on request.

Companders provided by default are:

- ENR Wis : for the optimization of noise

- ENC Wis : to optimize the voice

- ENR-1.2* / ENC-1.2*: to use MRP30-ENG with some

type of camera (ex. Canon® C300, Canon®

XF305, Sony® Pmw200, Sony® Pmw300, Sony®

PmwF5, Sony® Fs7, Nikon® D600 or Nikon®

D800, Canon® SD mark3...) which accept a

signal with reduced dynamic. This type of

expansion doesn't add artifacts to the signal

and allows to have a less noisy signal. It allows

to improve the quality of the audio

registration (compared to the ENR/ENC

standard) increasing the S/N ratio up to 15dB.

To use these companders, it’s necessary to set

ENR on the transmitter and ENR 1.2 on the

receiver or set ENC on the transmitter and

ENC 1.2 on the receiver.

ENR-1.2 it’s used for the optimization of noise,

ENC-1.2 it’s used to optimize the voice.

NB: The compander of the receiver must be the same as

the transmitter

It allows making three types of scan over a desired channel,

group or frequency. 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.

This function can be called also using the dedicated SCAN

button.

“Squelch scan” indicates the threshold below which a channel

is considered as free or almost free.

“Scan BTN” is the parameter to set the rapid function called

pressing SCAN button.

It’s possible to set Channel, Group or Frequency scan.

“View last” allows to see the result of the last scan operation.

“Deploy” allows to send to a MTK952 the last scan.

From the transmitter it’s possible to see the graphic of the last

scan and choose the frequency to tune.
