The menu is navigated by rotating the scroll wheel, and pushing it to open a submenu.
When in a submenu, pressing the ‘exit’ button will return to its parent menu.
5.1.2 Editing a parameter
To edit a parameter, navigate to it in the menu using the knob - square brackets [ … ]
will surround the currently highlighted parameter. Press the knob to select the
parameter, then rotate the knob to change it. When the desired value is attained, press
the knob to accept, then press exit to return to navigation mode.
Some parameters require a bit more space to edit –like text fields. For these parameters,
a dialog box will pop up allowing more space.
5.1.3 Text fields
When editing a text field, a ‘qwerty’ keyboard graphic will appear allowing entry or
modification of the full text. Turn the knob to select the letter, press it to set the letter. In
this menu, button 2 will toggle the ‘keyboard’ between upper case and lower case, and
button 3 acts as backspace/delete.
Scrolling through the text –the selected character will have a yellow rectangle around
it;
Modifying the current character –the character will be highlighted (it’ll be black on a
yellow background).

5.2 Display
5.2.1 Status box
This selection of the display gives real-time information on the status of the transmitter.
A Frequency The programmed frequency of operation. When the
transmitter is out of lock, such as at start-up, this will flash
between half and full brightness. When the exciter is locked, it
will show full brightness.
B Power The actual output power of the transmitter. After the exciter
has locked on frequency, the power will ramp up to the set
level. During this time the power display will flash between half
and full brightness. When the programmed power is reached,
the display will show full brightness.
If the RF has been muted either manually or automatically, this section will
show ‘RF MUTE’. If the reverse power is greater than 10% of the forward
power, this section will alternate between ‘FWD’ and ‘REV’ to display both
readings.
C Deviation Shows the current peak FM deviation of the transmitter. If the
deviation falls below 30kHz for 30 seconds, the deviation display will
flash to indicate abnormal modulation.
D Alarms Indicates which of the three alarms are set or triggered. The
presence of the letters A to C indicate when an alarm is
enabled, and when it is triggered.
If greyed out, the alarm is enabled but not triggered; If flashing, the alarm
is triggered.
For example:
Not shown = no alarms set.
ALM A=only alarm A is enabled.
ALM A B C =all alarms are enabled.
ALM A BC = all alarms enabled, A and C triggered.
An indication that an alarm has been triggered will also be shown on
the screensaver.

E PA Temperature / power supply voltages / reverse power.
This section displays the power amplifier temperature, the voltages of
the power amplifier power supply and the reverse power.
If FSK is enabled, this section will read FSK ACTIVE while the transmitter
is keying. This will only display for around 15 seconds every hour.
5.2.2 Menu Box
This is the main section of the user interface. Navigate by rotating the control knob and
select a menu option by pushing.
Button 1 is the ‘back’ button in this menu, and will move the menu selection up one
level.

6.1 Quick Start
Important: Never power on an FM transmitter without a suitable antenna or dummy load
connected. The V3 series transmitter’s protection circuitry will prevent any internal
damage, but it is not advisable to run an FM transmitter without a load connected.
The transmitter should be installed in a properly grounded rack or enclosure, the front
and rear ventilation slots should not be blocked in any way. Please note that the airflow
is front to back.
Note that the transmitter is shipped with the removable power supply modules not fitted.
Prior to use, these should be installed, as follows:
1. Unscrew the locking nut securing the removable ventilation grille.
2. Carefully slide the power supplies into the slots on the left.
3. IMPORTANT: Be sure to insert the correct way up –the locking tab at the bottom
with its arrow pointing up, as shown below.
4. Ensure that the power supply slides all the way in, and that the locking tab
engages.
5. Replace the grille, hand-tighten the locking nut.
Setting up a V3 series transmitter couldn’t be any easier. First connect either analogue
audio to the left and right back panel connectors (12), digital audio AES/EBU into the
RJ45 connector (if necessary use the supplied adaptor) (13) or feed the MPX input (14)
from an audio processor. Connect the RF output (7) to a 50ohm antenna of the correct
power handling capability. Connect the required remote control / monitoring ports
(Ethernet, RS232, Alarms/Triggers Port).

The transmitter’s frequency and power are both set from the RF Settings menu:
Input selection, pre-emphasis, processing and the stereo parameters are set in the Audio
Settings menu:
Input source Selects analog or digital input to the transmitter’s built -in stereo
encoder/audio processor. For analog, connect to left and right
XLR inputs. For digital, connect an AES/EBU connection to the
‘digital’ RJ45 connector, if necessary using the supplied XLR-RJ45
adaptor (which adheres to the StudioHub wiring convention).
Also selects whether the unit is fed from an external mpx generator
or digital mpx over AES signal.
MPX1/2 Input Allows selection of usage of the MPX1 and 2 input connectors.
MPX1/2 Output Allows selection of what signal is available at the
MPX1 and 2 2 output connectors.
MPX Generator Sub-menu: Settings for the internal MPX, multiplex or
‘composite’ generator.

set/check the proper pilot injection level.
12. Check the documentation that came with your RDS encoder on how to
set/check the proper RDS injection level.

In this setup, the audio stereo multiplex is generated in the audio processor. The RDS
data is fed into the audio processor where it is combined with the audio multiplex. This
combined signal is fed directly into the transmitter exciter. Note that the transmitter’s
onboard processing will have no effect on the signal in this configuration.
This is the best connection in terms of pilot and RDS subcarrier phase synchronization and
MPX spectrum cleanliness, if you’re not using the V3’s internal RDS and stereo
generators.

7.1 RF Setup
Note: Never power on an FM transmitter without a suitable antenna or dummy load
connected. The V3 transmitter’s protection circuitry will prevent any internal damage,
but it is not advisable to run a transmitter without a load connected.
7.1.1 Basic setup
1. Set the desired Frequency. Note that the frequency displayed in the status
box will flash for a few seconds, indicating that the system is out of lock and has
not yet reached that frequency. Once locked, the display will become steady.
2. Set the required Power. The system will take time to ramp the power to the
selected value. During this time, the value displayed in the status box will
flash.
3. Set the 100% modulation level: This will usually be 75kHz deviation –and should
only be adjusted under special circumstances and then with caution.
4. Select whether you require the unit to send the FSK ID every hour. If enabled,
enter the FSK ID (applies only to translator application in the USA).
5. RF Mute must be switched to off once the unit is set up, to allow it to transmit.
7.1.2 Power Scheduler
This feature will switch the output power of the unit to an alternate value set in Power
Scheduler | Power during the selected time interval. This is to allow you to lower the
power of the transmitter, for example at night, to reduce power consumption.
To set up this feature, enter the Power Scheduler sub-menu:
1. In Power set the power that the unit will switch to during the scheduled
interval;
2. Set the start time at which the unit will switch to this power level;
3. Set the finish time, when the unit will switch back to its normal power level;
4. Current time is the system time. This is displayed here as a reference for use
when setting the start and finish times. It can be adjusted if required.
5. Set Enable to On. The power scheduler is now running.
