General Description

Wisycom MRK980 is a true diversity, ultra-wideband dual channel receiver. With its 1090MHz

of band switching, it ensures the users an exceptional band flexibility, combined with a superb

selectivity and inter-modulation immunity, for best operating performances of the wireless

microphone systems. MRK980 also features an internal DSP processor, Wisycom famous

Multicompanding system, new Dante compatibility and a completely and renewed user interface,

which make this system easy and quick to setup.

MRK980 is designed to be:

“easy & quick to use” thanks to automatic setup functions (i.e. frequencies, squelch), remote

configuration utilities (Dante/Ethernet control connections), a display with intuitive context
menu navigation and shortcut buttons on the front panel.

“extremely flexible”, with an incredible frequency agility of 1090MHz (VHF/UHF/DME); more

than one rack can be connected together thru a simple ethernet cable to act as a multi-channel
receiver. Moreover the DSP board allows the units to work with several digital audio outputs
(i.e. AES/EBU, DANTE, …), with multi-companding compatibilities and the new adaptive
squelch function.

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

RF sensitivity and immunity plus a superb audio quality.

“a durable & upgradable investment”, thanks to the very robust design (aluminum housing)

and the possibility of upgrade/enhance units performances with simple slot in card (pc-like
thru the DEXB expansion bus)

Moreover MRK980 system is already set up for the exclusive PTT function (remote command),
developed and patented by Wisycom:

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.

 ATTENTION: supply the apparatus with a correct mains voltage and with the ground

connection. Check the power cord integrity.

 The power cord must be protected from damage.

 Do not install the apparatus near heaters or in hot environments, do not use outside the

operating temperature range.

 Mount the apparatus as indicated in the instruction, do not block side grids for air

ventilation.

 If the external air filter is mounted, clean it regularly.

 WARNING: do not open the apparatus, RISK OF ELECTRIC SHOCK!

 Do not open the apparatus, only qualified service technician are enabled to operate on it.

The apparatus needs servicing when is not properly working or is damaged by liquids,
moisture or other objects are fallen in the apparatus.

hazards or fire.

o

Keep attention on all the labels with warnings or hazards on the apparatus.

 WARNING: The apparatus is intended for professional use; anyway 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 the case of any kind of hearing problem.
