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.

Compander
MCR54 supports 5 different types of “Compander systems” (others on request through Digicom):
ENS: designed for voice and music applications.
ENR-Wisy: designed for maximum noise reduction. Ideal for use in louder environments.
ENC-Wisy: designed for maximum audio fidelity (use this in case of special vocal application or to
remote instruments). Ideal for use in quite environments.

MCR54 / MCR54-DUAL User Manual

ENR-1.2*/ENC-1.2*: to use 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 expanders, 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.
NOTE: The compander of the receiver must be the same as the transmitter
MCR54 core is a power digital audio processor that, besides an unbeatable audio quality and
flexibility, can emulate most expanders systems on the market. On this menu you can setup the
audio expanding chipset emulation. ENR is emulating the Philips™SA572 and PTT digital data of
Wisycom transmitters. Other setups can be loaded on request.

RF Squelch
RF squelch is a function that acts to suppress the audio output of a receiver in the absence of a sufficiently
strong desired input signal.

MCR54 / MCR54-DUAL User Manual
12
Noise Squelch
Noise squelch 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.
Tone Squelch
MCR54 is able to detect a digital tone squelch generated by a Wisycom transmitter (ex.
MTH410/MTH400/MTP40S/ MTP41S/MTB40S/RPU500).
Tone squelch ON: when the tone squelch is enabled the audio is muted unless the correct carrier is detected.
Tone squelch allows to work with lower RF squelch, increasing the coverage and the robustness especially in
presence of digital television carriers (DVB-T).
Audio
Max audio level output can be set:
•from 0 to -30 dBFs (1 dB step) for digital AES3 output
•from 18 dBu to -24 dBu (1 dB step) for analog BASE output
•from 18 dBu to -24 dBu (1 dB step) for analog TOP output
PTT
It’s possible to choose the status of audio output for the Base and the Top when transmitter’s PTT
button is pushed or released. The following table explains the logic used for the nomenclature:
[X]: indicates that audio output is enabled.
[ ]: indicates that audio output is disabled.
Phase
To change audio phase of 0° or 180°.
Cal. Tone
If Cal. tone is enabled, a calibration tone is transmitted from the outputs of the receiver and the
audio LED of the relative RX become blue (to turn off the calibration tone, go on the menu Advanced
>RX and press EXIT)

MCR54 / MCR54-DUAL User Manual
13
It’s possible to select the audio level between -30 dB to 0dB (referred to the maximum output level
set on the audio outputs). It represents the reference of the peak deviation (56 KHz).
The frequency of the tone can be chosen between 400/600/1000 Hz.
Sync
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 UP&EXIT buttons
together 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.
