•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 technicians are authorized 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.
WARNING: The apparatus is intended for professional use; 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.

MAIN FEATURES
MCR54 is a camera mount quad true diversity wireless-microphone receiver system in a modular
stand-alone or slot-in configuration (compatible with most camera’s slot):
•Wideband just isn’t enough anymore! Upgrade to a Multi-Band system with up 790 MHz
tuning range to find your frequency, anywhere in the World.
•With the combination of Narrowband Modulation (High Density) and Linear transmitters,
set your channels every 200kHz without intermodulation distortion and get an extra 3dB
sensitivity.
•With eight internal receiver boards, the MCR54 boasts an unprecedented capacity for
range and reliability.
•DSP delivers ENC and ENR algorithms for perfect audio in any application with less than
1ms delay –Create and shape presets for the desired sound. This enables the use of third-
party transmitters with Wisycom receivers
•Modular configurations for stand-alone or slot-in formats in many Cameras or Audio
Devices
•Monitor & control through USB C or Bluetooth 5 (long range) on Wisycom Manager 2.2
(computer SW)
•High contrast OLED display and 4 buttons enable quick manual setup
•DSP Analog & Digital Audio Output (AES3)
•Extreme low noise VCO with ultrafast spectrum scan for optimal quick & easy setup
•Wisycom exclusive digital sub-carrier telemetry technology enables:
oremote TX battery monitoring
oadvanced tone-squelch operating
oPush-to-talk function (via optional back-panel module):
Simply pushing this button (PTT), the presenter causes the remote switching of the
receiver’s output-line, from the “main line” to the additional “intercom line”, in order to
be able to talk “off-air” directly with the technical team. Then all PTT’s MICs can be
connected in pre-fading allowing a clever intercom setup.
•Rear antenna connectors and micro audio and power adapter
•40 groups of 60 channels fully user programmable (2400 frequencies)
TECHNICAL DESCRIPTION
The MCR54 is a professional quad true diversity receiver for wireless microphones reception
designed for broadcast television production, live performances, theatres and many other
professional applications.
The winning features:
▪High immunity on strong RF environment
▪Massive switching bandwidth
▪Dynamic audio performances and flexibility with analog or digital processors
▪Unprecedented reliability and durability

One of the milestones in the design of the MCR54 is unprecedented reliability: most of the circuitry
of the receiver is independent one from each other. Above a schematic with an overview of main
receiver functions.
RF layout:
For each antenna the RF signal is split in 4 to receiver 1,2,3 and 4 (antenna A and antenna B) with a
wide band splitter. Then 3 banks of filters are selected according to the frequency of the 4 receivers:
MCR54-B1 (UK)
MCR54-B2 (USA/EU)
MCR54-B3 (JP)
FILTER BANK 1:
470-800MHz Tuneable filter with 32MHz of bandwidth
FILTER BANK 2:
961-1000 MHz
823-832 MHz
806-810 MHz
FILTER BANK 3:
1045-1075 MHz
940-960 MHz
1240-1260 MHz
NOTE: the tuning frequencies of all the 4 receivers has to be in the same bank of filter!
All the 4 receivers are true diversity receivers: each one is made of two receivers tuned on the same
frequency. Subsequently the selection of the band filter between 100 kHz or 200kHz allows to work
with Narrowband (High Density) or Wideband transmitters respectively.
Each receiver has its own demodulated signal and its own RSSI signal (Receiver Signal Strength
Indication); RF squelch used measurement of RSSI level for antenna diversity and for audio enabling.
In addition to the RSSI level, each receiver measures the Channel Quality. It is a more powerful tool
than RF squelch because it actually looks at the quality of the signal from the TX relative to the noise
floor on the channel which can vary over time. With the noise squelch set to on you can set the RF
squelch to a much lower level.
A DSP selects or combines signals from section A & B to have the best audio.

Audio Layout
As shown on the above schematic, MCR54 provides the following audio signals:
•HP [HEADPHONE]: an analog monitor audio output to headphone 3.5mm jack socket.
Thanks to the “Setup>Headphone” menu the user can select which of the 4 receivers he
wants to listen to and can adjust the volume from 0 to -24 step 1dB.
•BOT [MAIN]: 4 audio signal streams come out in the connector on the bottom and
depending on the plugged slot-in can be configured according to the following table:
