MRK 960 Modular Wireless-Microphone Receiver System

19” 1U module, stackable, with dual true diversity receivers

Main Features

Wide bandwidth: up to 370 MHz with tunable filters (2 ch’s independent):

470 MHz to 840 MHz (Europe TV ch. 21/67) with internal active splitter

Extreme immunity: IIP3 > 20dBm, practically intermodulation free

Powerful and quick: thanks to the latest DSP class “shark” by Analog Design

(2Gigaflops 40bit power), providing the highest audio quality (40bit floating point)

and a delay of only 0,39 msec (AES3 output) and 0,46 msec (analogue output)

Audio quality: Analogue (electronically balanced) and digital output (AES3)

Network: 2 USB’s connectors for configuration/monitor and cascade rack

connections and a Ethernet 10/100 base TX port (RJ45) for network connection

Automatic scan: for best channels, squelch and other automatic setup

Infrared interface (i.e. for system setup, microphone programming).

Automatic reprogramming of transmitter (thru infrared)

PC Software to monitor/setup units, spectrum analyzer mode, intermodulation

free frequencies calculator, embedded database by area or to archive existing

setups

Optional (upgradable):

Multicompanding (/DIGCOM1)

Ethersound interface in alternative to AES3 (/ETH)

Patented PTT (Push to Talk) function with audio exit and GPI signals (/PTT)

Low impedance transformers outputs (/XLR on line ports or /XRC on ptt ports)

General Description

The system presents exceptional selectivity and inter-modulation immunity for best operating

performance of the wireless-microphone system even in the presence of DVTB-T transmitter’s signals.

MRK 960 is designed to be:

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

configuration utilities (USB/Ethernet), display with intuitive context menu navigation.

 “extremely flexible”, in fact each of the two receivers can work in a 240 MHz bandwidth, more than

one rack can be connected together thru a simple USB cable to act a multi-channel receiver.

Moreover, the DSP interface allows the units to work with several digital audio output (i.e. AES/EBU,

Ethersound,), multi-companding compatibilities and other digital features.

 “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 of upgrade/enhance unit’s performances with simple slot in card (pc-like thru the DEXB

expansion bus).

Moreover, MRK 960 system is already set up for the exclusive PTT function, recently developed by

Wisycom and now appreciated in the broadcast world. It’s able to work directly with the new wireless

microphones provided with built-in telemetry (either body-pack or hand-held transmitters) and Push-To-

Talk button: simply pushing this button, 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 (optionally a stuttering tone is back generated to signal the presenter of

the push to talk status).
