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
“a durable & upgradable investment”, thanks to the very robust design (aluminum
housing) and the possibility to upgrade/enhance units performances.

Edit RX menu
Selecting this sub-menu most of RX1 setups are
configurable
Edit RX menu > Gr-Ch submenu
Select current group and channel. Group name and
channel frequency are displayed on the right.
Edit RX menu > Frequency submenu
If the specific group/channel is not locked, then can
be edited in this menu.
Edit RX menu > Squelch submenu
This menu allows to disable the RF squelch or to
setup the desired squelch level in dBuV (note 0 dBuV
is equal to -107 dBm).
10
Edit RX menu > Expander submenu
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. ENR is emulating the
Philips™ SA572 and PTT digital data of Wisycom
transmitters. Other setups can be loaded on request.
Edit RX menu > Tone sq. submenu
MPR30-ENG is able to detect a digital tone squelch generated by a Wisycom transmitters
Tone squelch ON: when the tone squelch is enabled
the audio is muted unless the correct carrier is
detected. Tone squelch allows working with lower RF
squelch, increasing the coverage and the robustness
especially in presence of digital television carriers
(DVB-T).
Tone squelch OFF: the audio is muted if RF level <
Squelch level
Edit RX menu >LINE submenu
It is possible to set the nominal audio from +18dBu
(peak deviation) and -35 dBu:
LINE: -5 dBu ÷+18 dBu (1 dB step)
MIC: -35 dBu ÷-12 dBu(1 dB step)
Edit RX menu > Sig. phase submenu
To change audio phase of 0 deg or 180 deg.
Edit RX menu > Scan submenu
This function can be called also using the dedicated
DOWN/UP button (push and keep). It allows making
a scan over a desired frequency group.
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.
11
Once started a scan operation the receiver asks for group
to be used*.
Then it prompts to turn off all
transmitters.
Then finally
start the scan!
After few seconds, scan results are displayed on a chart.
Pushing simultaneously UP and DOWN button, the results
can be also displayed
sorted by level,
making easier to pick
up the best one.
(*)As per Wisycom standard, group 00 and group 01 are special; respectively the “center
frequency” (474,482/... MHz) and the intergap frequency (i.e. 470/478/486/... MHz). A scan on
group 00 will reveal in few seconds the overall DVB-T occupation on the area, while a scan on
group 01 will give possible working frequency, usable also in presence of strong DVB-T signal
(sort to speak working in the band-guard of 2 digital television channels).
Edit RX menu > Cal.Tone submenu
Calibration Tone function generates a 1 KHz sine
audio at the audio outputs (LINE and headphone) at
the level selected (-18dB or 0dB). Select the level and
push SEL Button to start calibration tone function.
Then push EXIT button to stop it.
12
Display menu
This menu allows to configure display setting
Edit Display submenu
3 LED setting are available:
Full: LED indicators works normally
Alarm: LED indicators lights up only when an alarm
happened
OFF: LED indicators remain off
Change contrast display from 0 (min) to 5 (max).
Low timeout sets the timeout from 5 to 60 seconds
to decrease the brightness display.
Off timeout sets the timeout from 10 to 120 seconds
to turn off the display. With OFF setting the display
never turns off.
Infrared menu
By this menu, MPR30-ENG can be connected to IRDA
for setup or firmware upgrades.
NOTE: while in this menu display is not automatically turned off.
13
Sync menu
The SYNC function is useful to tune a transmitter
on the same frequency of the receiver via the IR
interface. Before starting the sync function tune the
receiver on desired channel, manually or using the
SCAN utility. After this, enable the IR interface on
the transmitter. Now press SYNC button or enter in
the Sync menu to start the SYNC function. Keep the
IR window of the transmitter in front of the IR
window of the receiver and, as soon as the
connection is done, the receiver will send to the
transmitter all the information needed. If the
operation is not possible,
(i.e. the frequency range of the transmitter is not
compatible with the frequency of the receiver), the
display will show an error message. If the transmitter
has the function “NAME” enabled, when the sync
function is completed it will show the same name of
the synchronized receiver
