4.1 Unpacking
The package contains:
1 BLUES30NV or BLUES50NV
1 User Manual
1 Mains Power Cable
The following accessories are also available from Your R.V.R. Dealer:
• Options for the machine: /TLW-BLU-E
• Spare Parts
• Cables
4.2 Features
This exciter contains a low-pass filter that reduces the harmonic emissions to
below the limits allowed by international regulations (CCIR, FCC or ETSI), and
can therefore be used as a transmitter connected directly to the antenna.
Important features of the BLUES30/50NV are the extremely compactness, the great
simplicity of construction and use, and the presence of built-in high-performance
coder stereo. BLUES30/50NV futhermore was designed to be modular: its various
functions are carried out from modules directly connected to each other with male
and female connectors or with flat cables ending in connectors. This type of design
makes maintenance operations and any required module replacement easier.
The machine is ready for both LEFT and RIGHT inputs, thanks to the stereo coder; or
can be configured to operate in Mono/MPX mode, i.e. excluding the stereo coder and
using LEFT inputs such as MONO input and BNC, always-on, such as MPX broadband
input, which is useful when youwantto transmitinstereousinganexternalstereo coder.
La macchina è inoltre predisposta per ingressi digitali AES\EBU. The equipment
comes with digital inputs AES\EBU.

5. Quick guide for installation and use
This section provides a step-by-step description of equipment installation and
configuration procedure. Follow these procedures closely upon first power-on
and each time any change is made to general configuration, such as when a new
transmission station is added or the equipment is replaced.
Once the desired configuration has been set up, no more settings are required
for normal operation; at each power-up (even after an accidental shutdown),
the equipment defaults to the parameters set during the initial configuration
procedure.
The topics covered in this section are discussed at greater length in the next
sections, with detailed descriptions of all hardware and firmware features and
capabilities. Please see the relevant sections for additional details.
IMPORTANT: When configuring and testing the transmitter in which the equipment
is integrated, be sure to have the Final Test Table supplied with the equipment ready
at hand throughout the whole procedure; the Final Test Table lists all operating
parameters as set and tested at the factory.
5.1 Prepation
5.1.1 Preliminary checks
Unpack the exciter and immediately inspect it for transport damage. Ensure that
all connectors are in perfect condition.
The main fuse can be accessed from the outside on the rear panel. Extract the
fuse carrier with a screwdriver to check its integrity or for replacement, if necessary.
The fuse to be used is this type:
Mains Fuse
BLUES30NV
@ 90÷260 Vac (1x) 3.15A type 5x20
BLUES50NV
@ 90÷260 Vac (1x) 6.3A type 5x20
Table 5.1: Fuse
Provide for the following set-up (applicable to operating tests and putting into
service:
√ 90 VAC÷130 VAC or 180÷250 VAC mains power supply, with adequate earth
connection.

10 / 28 User Manual
Rev. 1.0 - 29/11/16
BLUES30/50NV
ELETTRONICA
√ For operating tests only: dummy load with 50 Ohm impedance and adequate
capacity (30/50W minimum).
√ Connection cable kit including:
• Mains power cable
• Coaxial cable with BNC connectors for interlock signal connection
• RF cable for output to load / antenna (50 Ohm coaxial cable with N-type
connector)
• Audio cables between transmitter and audio sources.
5.1.2 Connections
Connect the RF output of the transmitter to the antenna cable or a dummy load
capable of dissipating amplifier output power. To begin with, set exciter to minimum
output power and switch it off.
Connect the transmitter INTERLOCK IN input to the matching INTERLOCK OUT
output fitted on R.V.R. Elettronica equipment to act as hybrid couplers. If your
equipment is a different brand, identify an equivalent output.
Figure 5.2: connections with amplifier
WARNING: Electric shock hazard! Never handle the RF output connector
when the e�uipment is powered on and no load is connected. Injury or death
may result. .
Ensure that the POWER switch on the front panel is set to “OFF”.
Connect the mains power cable to the MAINS connector on the rear panel.

Note: the mains must be equipped with adequate earth connection properly
connected to the equipment. This is a pre-requisite for ensuring operator safety
and correct operation.
Connect the audio and RDS/SCA signals from user’s sources to the transmitter
input connectors.
5.1.3 Encoder
The interaction between the user and the exciter control software is performed
using the encoder.
Ruotare l’encoder verso sinistra
per spostare il cursore verso il
basso, per decrementare il valo-
re di un parametro o per selezio-
nare un elemento di una lista
Ruotare l’encoder verso destra
per spostare il cursore verso l’al-
to, per incrementare il valore di
un parametro o per selezionare
un elemento di una lista
Premere il pulsante una volta per
entrare nel menù desiderato, quindi
una seconda volta per modificare il
parametro selezionato.
The operations that you can perform on the encoder are:
• rotation: moves the cursor shown on the display; if you turn the encoder to
the left (counterclockwise), the cursor moves downwards, if you turn it right the
cursor moves upwards; it also permits to increase or diminish the parameters
(turning the encoder left diminishes the paramete.
• pression: push the button once when the cursor is on the name of a menu to
enter in that menu, push it when the corsor is on the name of a parameter to
enter in modification mode (the cursor starts blinking); after the modification of
a parameter, push the button to save the new value.
After having modified the value of a parameter, the cursor goes on blinking for
approximately 15 seconds, waiting for confirmation from the user. If the user
doesn’t confirm the new value (i.e., the button is not pressed), the parameter has
not saved and remains on the selected parameter.
The first pressure of the encoder when the display is light out, or its rotation, serves
in order to activate the retroillumination.

5.2 First power-on and setup
Perform this procedure upon first power-up and each time you make changes to
the configuration of the transmitter this component is integrated into.
Note : Standard factory settings are RF output power off (Pwr OFF) and regulated
output power set to upper limit (unless otherwise specified by customer).
5.2.1 Power-on
When you have performed all of the connections described in the previous
paragraph, power on the exciter using the suitable power switch on the front
panel.
5.2.2 Power check
Ensure that the ON LED turns on. Equipment name should appear briefly on the
display, followed by forward power and modulation readings. If the RF output is
disabled, those readings will be zero.
When the PLL locks to operating frequency, the LOCK LED will turn on.
5.2.3 How to enable the RF output
Check output power level and set it to maximum level (unless it has already been
set) from the Power Setup menu that you will have accessed by pressing the
following sequence of key: ESC (opens Default Menu) ⇒ENTER (hold down for
5 seconds) ⇒SET ⇒use keys to set bar to upper limit.
Check the state of the Pwr output power by the Fnc menu. If it is set to OFF, press
ENTER to bring the selection to ON.
5.2.4 Output power level control
NOTE: The exciter incorporates Automatic Gain Control (AGC) and output power
is modulated based on the power level set by the user and actual operating
conditions, such as temperature, reflected power and other parameters. Please
read section 5.3 for more details of RF power modulation.
To change the power level set, hold for about 5 seconds the ENCODER until to
you can get into edit mode.

The screen in edit mode will look like this:
The bottom line gives the instantaneous power (50W in this example), to increase
the level, turn to the right to turn to the left. Once you reach the desired level, press
the ENCODER to confirm and exit to the default menu. Note that the set value is
stored anyway, so if you leave the timeout without pressing any key, the power
will be the last level set.
The value at the side of SET provides a percentage indication of power setting;
please consider that the forward power readout provided on the display (FWD:
xxxx W) reflects actual output power reading, which may be lower than regulated
power supply when Automatic Gain Control is running in power supply
limitation mode (please read section 5.3 about RF power supply modulation for
more details).
NOTE: Output power may be set using the Pwr OFF control. In this condition, the
output power readout (Fwd) on the display will read 0 (zero); the SET bar will reflect
any adjustments you make using the keys and provides a graphic indication of how
much power supply will be delivered the moment you return to Pwr On state.
5.2.5 Changing the Power Good alarm threshold
Change Forward Power Good alarm setting PgD from the Fnc menu as desired
(factory setting is 50%).
5.2.6 Setting equipment I2C address
Change the IIC address in the MIX (Miscellaneous) menu as desired (factory
setting is 01).
5.2.7 Adjustments and calibration
The only manual adjustments are the level adjustments and the audio mode
adjustment.
The rear panel holds the trimmers for all transmitter inputs. Trimmer identification
is printed on the rear panel. Input sensitivity can be set within the limits set out in
the tables below through the trimmers:

When setting input sensitivity, please consider that the default menu reports
instantaneous modulation level and an indicator provides a 75 kHz reading. To
ensure correct adjustment, apply a signal with the same level as user’s audio
broadcast maximum level and then adjust using the trimmer until instantaneous
deviation matches the 75 kHz reading.
To set subcarrier input levels, you may use the same procedure and option “x10”
available in the Fnc menu. With this option, modulation level is multiplied by a factor
of 10, which means that default menu bar meter reflects a 7.5 kHz deviation.
A special menu with separate indications of Left and Right channel levels and
relating indicators of nominal levels for maximum deviation (75 kHz) is provided.
The settings of pre-emphasis, the impedance inputs of L & R, MPX and AES/EBU,
and the operation mode of the machine are operation that you can perform through
the Set menu.
5.3 Operation
1) Power on the exciter and ensure that the ON light turns on. Equipment name
should appear briefly on the display, quickly followed by modulation and forward
power readings (Menu 1), provided that the transmitter is delivering output
power.
Menu 1: x10 is Off Menu 1: x10 is On
NOTE: the indication aMod identifies that the audio input is set to Analogue;
the indication dMod identifies that the audio input is Digital.
NOTE: xMod identifies that the modulation display mode is selected in x10
through Fnc menu.
