QUICK USER GUIDE
MRK 960 - FRONT PANEL FUNCTIONS
MRK960 allows an easy and quick configuration using buttons, push knobs and displays.
The front panel is functionally divided in the following section:







Power & Booster: Receiver and antenna powering;
Monitor: monitoring audio with on headphone jack (6.3mm - ¼”);
Receiver 1: “receiver 1” configuration and monitor of radio/audio levels;
Receiver 2: “receiver 2” configuration and monitor of radio/audio levels;
Scan & Squelch: automatic scan and squelch settings;
Infrared: remote controlling and MIC setup through infrared.
POWER & BOOSTER
BOOSTER switch activates antenna powering (boosters) with 12VDC/200mA
MAX for each antenna and the green LED is lighted (a blinking LED indicates a
faulty condition; in this case power down the device and check for short circuits).
Booster supply for antenna A and antenna B are independent, switchable from
the radio->options menu.
ON/OFF square powering button turns on/off the receiver (when in off position
both power line phases are disconnected from power line).
MONITOR
Monitor 1 and Monitor 2 activates monitor on jack output (6.3mm - ¼”)
for receiver 1 and 2, respectively (a green LED is lighted when a receiver is
selected). Audio level can be adjusted with the rotary knob. A blinking red
led (CLIP) means clipping in the audio monitor output.

Setting Frequency (Menu  Radio  Channel/Group Frequency)
Current frequency can be quickly selected using the
rotary knob. Push enter button or rotary knob to
confirm current field editing and start modifying the
following field (frequency integer part  decimal
part, units=MHz).
The new selection can be saved (save button) or push
EXIT button to exit without saving.
Setting Group Name (Menu  Radio  Gr name)
Each group of frequencies can be associated to a short
name and a description. The short name can be edited
from the front panel of MRK960.
After choosing the group number with the knob, push
the knob to edit the name. Turn the knob to change
the selected character and push the knob to switch to
next character of the name (or use the buttons). Use
buttons to save/exit from the name editor menu.
Setting Squelch Level (Menu  Radio  Squelch)
Rotate the knob to modify the squelch value in the
allowed range (OFF to 1000 Volt or OFF to
60dBVolt, depending on the selected unit).
Push the knob to switch between squelch level and
squelch unit (Volt or dBVolt).
The new selection can be saved (save button) or push
EXIT button to exit without saving.
NEXT button has the same function as pushing the
knob.
Walk test (Menu  Radio  Walk test)
The WALK TEST menu allows a 90 sec recording of
the received signal for A and B antennas; the result is
displayed on the display. The sample rate is one
sample per second but the value displayed in mode
A&B, A, B (chosen with the first button) is the
minimum level of the RF signal received on each
antenna. Selecting MAX AB (pushing the first button),
the maximum level of signal received is displayed.
The unit for RF level is the same chosen for the
squelch level (dBVolt or Volt).
Change the mode (first button) to restart the recording
or just exit from the WALK TEST function.

Audio parameters (Menu  Audio)
Audio settings:
 Noise reduction (compander system): allows
choosing the preferred compander system.
 Tone sq.: tone squelch selection:
<Off>, tone squelch is off.
<On>, tone squelch is on and audio is enabled only if
the remote management sub-carrier is detected.
<Adv>, in advanced mode it is possible to use PTT (push to talk) function and manage a
remote commutation on secondary audio output or more complex commands (ex. GPI,
selectable with the config submenu, first button, active when ADV is selected; see picture
below).
 Out level: It is possible to attenuate the audio output level at 0/6/12 dB from the nominal
level. A switch for a further 30dB attenuation for MIC level output is located on the back
panel near the XLR audio connector.
 Cal tone: activating this option a 1KHz calibration tone is enabled on audio output. The
output level is 6dB below clipping and it is possible to activate audio output on LINE out,
COM out (optional) or in both outputs.
 Frequency diversity: This option is normally set to OFF. Set to YES when you need:
 to increase the reliability in case of failure
 to increase the reliability in case of transmitter batteries empty
 to increase the security against fading due to reflections on the radio link
When a receiver is set to frequency diversity YES, the audio output is calculated from the best
RF signal received from the two receivers.
WARNING: two transmitters tuned with the two receivers must be placed on the same audio
source and must have the same configuration (ex. gain, tone squelch setting, RF power, distance
from the audio source….). NOTE: the Noise reduction can be different.
Frequency diversity in each receiver can be set independently.
NOTE: With frequency diversity enabled (set to YES), the Tone Squelch menu allows only the
setting options ON and OFF (the ADV option is not allowed).

Tone squelch advanced config:
This submenu allows access to the matrix
configuration of audio outputs and GPI command
(COM and GPI are optional) depending on the
subcarrier tone from the transmitter.
 On the row TSQ OFF it is possible to activate or not the audio output on LINE and/or COM
outputs with or without subcarrier signal present.
 On the row TSQ ON it is possible to activate or not the audio output on LINE and/or COM
outputs only when the subcarrier signal is present. Without subcarrier signal all outputs are
off.
 On the first row of TSQ ADV it is possible to activate or not the audio output on LINE
and/or COM outputs plus GPI command only when the subcarrier signal is not present.
On the second row of TSQ ADV it is possible to activate or not the audio output on LINE
and/or COM outputs plus GPI command only when the subcarrier signal is present.
AUTO-SET
SCAN is an automatic scan function for all active frequencies of the selected group.
This is a quick way to find the lowest noise frequency to work with.
Once pushed, you need to select the group of frequencies to scan and an optional
voltage level line on the graph, just for your reference. Pushing START the receiver
(after one message) starts to scan all the frequencies and shows the result on the
display. Push the knob to change the x-axis of the graph between channel number and
rank; this second choice displays the less noisy channels on the left part of the graph.
Rotate the knob to switch between all the channels. Select the squelch to off to hear
the received signal even if it’s RF signal is lower than the squelch of the receiver.
Pushing SELECT button the receiver will be tuned on the selected channel thru the
knob.
SQ is an automatic way to quick setup the squelch for current frequency. The
transmitter must be off, then push SQ button to let the system find the optimal value.
This setup can be saved or not saved.

REMOTE MANAGEMENT
Network connections
MRK960’s can be easily cascade connected using the 2 usb ports ((current SW version support 4
racks cascade max for each daisy chain).
On the below example the unit on the top behave as a single 8 receiver rack (concentrating remoting
data from the below receivers); this way all the units can be easily monitored/configured thru a
single USB interface or Ethernet connection (a single IP).
