BRIEF DESCRIPTION

MPR30 is a compact true diversity receiver designed for professional in-ear monitoring

applications. This receiver features a real TRUE DIVERSITY configuration along with a unique

wideband tuning range up to 232 MHz. Audio processing can be Stereo MPX or mono based.

The output audio stage is especially design to have maximum audio peak-dynamic of 200

mWatt.

MPR30-IEM is designed to be:

“easy & quick to use” thanks to

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

oremote configuration utilities (thru infrared or micro-USB interface) using

Wisycom ENG RX Manager application

oOLED display with intuitive context menu navigation

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

oMPR30-IEM-N: 470/700 MHz (TV ch 21/49)

oMPR30-IEM-M: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 (aluminium

housing) and the possibility to upgrade/enhance units performances.

PARAMETER

SETTING

MEANING

Out mode

Stereo

The left and right signals are available as usual. The

Balance setting serves to adjust the balance between

the left and right stereo signal.

Mix

The left-right signals are mixed and are available as a

mono signal in both headphone channels.

The Mix mode setting serves to adjust the relative levels

of the two separate channels in the mixer mono signal.

Pilot tone

Yes

When the Pilot tone is enabled, the audio output is

muted unless the correct carrier is detected. Pilot tone

allows working with lower RF squelch, increasing the

coverage and the robustness especially in presence of

digital television carriers (DVB-T).

When the Pilot tone is disable, the audio output is

muted if RF level < Squelch level

For the presence/absence of audio output, check the upper symbol in the

status display

Balance

When Out

mode set to

Stereo

This menu allows to adjust the balance between the left

and right stereo signal in 35 steps.

Push UP/DOWN button to change the balance.

Mix Mode

When Out

mode set to

Mix

This menu allows to adjust the relative levels of the two

separate channels in the mixer mono signal in 35 steps.

Push UP/DOWN button to change the level.

Pwr limit

OFF

32Ω100mW

32Ω50mW

32Ω30mW

16Ω100mW

16Ω50mW

This menu allows to limit the power output. Set the

proper impedance@power according to the earphones

used.

NOTE: if set to OFF, there is no power limit control.

Vol. boost

0/3/6/9/12dB

This menu allows to increase the volume of the output

headphones, selectable in 3 dB steps from 0 dB to 12

dB. Set the appropriate volume boost and then adjust

the volume with the control knob.

Equalizer

-12dB/+12dB

This menu allows to equalizer Low and High frequencies

of the audio (2dB steps from -12dB to 12dB )

1. Push UP/DOWN button to increase/decrease

the gain of the Low frequencies (50Hz)

2. Push SEL button to shift on High frequencies,

3. Push UP/DOWN button to increase/decrease

the gain of the High frequencies (10kHz)

4. Keep push SEL button to SAVE
