dual true diversity receiver

OPTIONS:

Name

The options 

naMe

 allow you to change the name of 

the receiver. This is the name displayed in the top of 

the display in the main view and is the name sent 

to the transmitter with the sync function (for trans-

mitters with this advanced capability). Use the knob 

to change the name and the buttons to save or exit 

from the function.

LCD contr.

 & 

LCD light

With these two functions it is possible to change the 

contrast or the backlight intensity of the LCD display. 

Use the knob to change and the buttons to save or 

exit from the function.

or information of your MRK950 receiver:

 

»

 Range of frequency

 

»

 Internal temperature

 

»

 Serial number

 

»

Internal errors counter (could be read and re

-

set from the 

Wisycom Manager 

software)

 

»

 Bootloader firmware version

ond time to exit this function.  

Restore preset

The 

ResToRe PReseT

 resets the following setups

-

tion system (ENR), audio output level (12dBu), cal 

tone (OFF), audio matrix, booster supply (OFF) and 

headphone selection (OFF).

Note: receiver names, frequencies, groups or 

channels information are NOT changed.

Noise red.

The 

noise  RedUcTion  sYsTeM

  is  used  to  se-

lect your current noise reduction system in the audio 

path. If the DSP board is not installed it is possible 

to  change  only  between  ENR  (the  n.  r.  system  of 

the  Wisycom  wireless  microphones)  and  “NONE”. 

The NONE position excludes the audio expander and 

the receiver works as a normal FM receiver with 50 

microseconds  of  de-emphasys  and  20KHz  of  audio 

bandwidth. If the DSP board is installed then it is pos

-

sible to choose different types of audio processors. 

Use the buttons to save or exit from this function. 

Depending on selected NOISE REDUCTION SYSTEM, 

tone squelch function and transmitter battery status 

could be enabled or disabled  (since not all the wire-

less microphones have this enhanced functionality).

Tone sq.

The 

Tone sQUelcH

 function is an advanced func-

tion  (whose  behaviour  depends  on  selected  noise 

reduction  system).  This  chapter  explains  TONE 

SQUELCH operations when associated to a Wisycom 

wireless  microphone  with  the  ENR  as  active  noise 

reduction  system.  Other  types  of  wireless  micro-

phones could have different behaviour or could not 

work properly. Here-after the complete tone squelch 

function,  whenever  the  receiver  does  not  have  all 

the  options  installed,  some  functions  will  be  hid-

den.  The tone squelch selection could be OFF, ON 

or  ADV  (advanced).  Tone  squelch  OFF  enables  the 

audio output on LINE and COM (if present) connec
