1. INTRODUCTION
1.1. General information
1.1.1. About Ecreso
Founded in 1956 near Bordeaux, ECRESO was created by radio broadcasting enthusiasts and counts
today as one of the most important player on the international broadcasting stage.
Ecreso offers a line of analog and digital radio transmitters and digital television transmitters
(DVB-T/H, DAB, DAB+, T-DMB), low power or high power, either water or air cooled.
ECRESO is today part of the WorldCast Systems Group and as such, it proposes solutions for remote
control, audio measuring, sound processing, RDS encoding and transmission network monitoring.
1.1.2. About the NEXT FM
Research Program supported by the French Council of Aquitaine.
The Next FM is the first ‘All in One’ FM transmitter which includes digital audio processors, a stereo
encoder plus additional innovative features such as an RDS encoder, embedded audio backup, I/O
remote control and TCP/IP connectivity.
Ecreso’s innovative approach of combining a high quality transmitter with essential broadcast
functionality allows many savings to the broadcaster in terms of cost, real estate, time and energy.
The NEXT FM takes less space at the transmitter site, draws less power and is a highly competitive,
cost-effective alternative to purchasing a range of separate devices. With a single, integrated user
interface to control all functions, the NEXT FM also enables greater user efficiency.
Key features of the NEXT FM:
¾0.5, 20 or 100 W FM modulator and RF amplifier
¾Sound Processor: 1, 2 or 4 bands (software upgradeable in 2 or 4 bands)
¾Audio Backup
¾RDS Encoder
¾Stereo Encoder
¾Power backup system
¾I/O Remote control for a total solution
¾FM receiver for rebroadcasting and monitoring
Several applications, that can be launched from the Radio all in one portal or from the front panel, give
access to those functions, each with its own user manual :
¾Radio all in one: main application which includes RDS, audio backup, transmitter
configuration, unit status and system configuration.
¾Sound4 powered Digiplexer Sound Process: sound processing application,
¾ScriptEasy v.2.3.7 and MasterView v.1.3.1*: remote control and automation application
and creation of end-user views.
Whether remote or local, these applications work in similar ways.
Layout differences (login window, virtual keyboard) exist and are described in the applicable manual.
* Only the MasterView Viewer is available from the front screen application.
To ensure optimal performance, do not start 2 remote applications at the same time.

1.2. Before beginning
So as to preserve the safety of the devices and to ensure operations without danger, the user must
respect the following instructions, symbols and precautions:
1. The device should only be operated in the conditions described in this manual.
2. Nothing must obstruct the ventilation.
3. The device must only be used with a plug that incorporates a protective ground
contact.
4. To avoid any risk of electrocution, the protection conductor must not be cut,
intentionally or not, either on the device or on the power cord.
5. Before switching on the device, be sure that the nominal voltage specified on the
device corresponds to that of the mains’ nominal voltage.
6. To avoid any electromagnetic interference, the device must only be used when it
is closed. Shielded cables are mandatory.
7. The device should only be operated on a stable electrical network. If the electrical
network is not stable, a power conditioner, such as a UPS, must be used.
8. Any operation concerning maintenance, adjusting or repairing must be carried out
by qualified staff.
¾Caution: LITHIUM BATTERIES
If the battery is not correctly replaced, there will be a risk of explosion.
Only replace it with a battery of the same type. Contact Audemat before attempting to use
another type.
Do not throw away used batteries; send them back to us.
1.3. Licenses and options
Depending on the package you purchased, software and hardware options may be included;
otherwise, they may be or acquired.
¾Software options:
¾Full RDS:
Configure up to 10 DSN (on 2 in basic RDS),
Manage EON (up to 9 EON in addition to the main PSN per DSN),
Manage SLC,
Configure ODA.
¾Advanced Audio Backup: creation and management of embedded playlists that will
replace the analog or AES inputs in case they fail.
¾MasterView: with this application, visualize and control your site in custom views.
¾1 to 2-band upgrade.
¾2 to 4-band upgrade.
Please see Appendix A of this manual for upgrading procedures.
¾Hardware options:
¾Input / Output modules:
•Digital inputs: this module provides 16 digital inputs on a female SUB-D 25.
•Relay outputs: this module provides 8 relay closures on a male SUB-D 25.
•Analog inputs:this module provides 8 analog inputs on a female SUB-D 25.
Five slots are available on the NEXT FM, to set up to 4 digital input modules, up to 5
relay output modules and up to 1 analog input module.

¾Redundant power supply: in case one power supply fails, the other one takes over, thus
allowing the unit to operate with no interruption. Also includes a UPS (Uninterruptible
Power Supply) to make it possible to send an alarm in case of complete power failure.
Please see Appendix B of this manual for input / output configuration.

3.1. Starting the equipment
Page 11
Head Office : Parc d’activites Kennedy - 20, avenue Neil Armstrong – F-33700 Bordeaux-Merignac (France)
Tel [phone] – Fax [phone] – www.ecreso.com – [email protected]
DO NOT PLUG IN THE UNIT.
!
1. Install the dust filter if the unit’s environmental quality requires it (see diagram next page).
2. Connect the transmitter RF output to a 50 ohm charge with a wattmeter (see connection diagram
next page).
The 50 ohm charge power to use depends on the transmitter power:
¾Greater than 2 W for a 0.5 W transmitter.
¾Greater than 30 W for a 20 W transmitter.
¾Greater than 150 W for a 100 W transmitter.
When you acquired your NEXT FM, the RF amplifier is deactivated and power is set to 0. These
settings will then be adjusted using the front panel application.
For safety reasons, always deactivate the amplifier and the power if the NEXT FM is not in
use.
3. Connect the inputs. The AES input is the default main source, but if the analog input is the only
connected input it will become the main source. Please read the sound processing manual for
input management.
4. Connect to power using provided cable (or cables with “Redundant power supply” option). Press
the reset button using an adjustment screwdriver.
3.2. Installing the dust filter
1. Using a phillips screwdriver, unscrew the 5 screws from the front panel so as to be able to
remove it.
2. Set de dust filter in front of the fan, with the grid towards the fan.
3. Screw the front panel back in place with the 5 screws.
Note: make sure the fan works properly after starting the unit. If not, the front panel might not be
properly screwed.

1 The 3 dB alarm is triggered on threshold overshoot as set on the transmitter page (see section 7).
This alarm indicates a problem with the amplifier or at the output. Check the antenna and cables which
can be unplugged or defective.
2 The VSWR alarm is triggered on threshold overshoot as set on the transmitter page (see section 7)
or when the unit goes into hardware protection mode when the VSWR is too high. This alarm indicates
a problem with the amplifier or at the output. Check the antenna and cables which can be unplugged
or defective.
3One of the PSU is not working. Check the main supply.
4If the Warning LED blinks when the main power is back on, it indicates that the unit is powered by the
UPS (“Redundant Power Supply" option) but has not started yet. Simply use the “Reset” button on
the front panel to restart the unit.
If the Warning LED is on, please contact the support department.
3.5. Configuration using the front panel application
The front panel screen gives access to the NEXT FM’s
various applications; however, it is first used to configure the
unit.
1. The front panel screen displays the status page which
gives an overview of the main functions (transmission,
RDS, audio backup…).
2. In order to be able to configure the NEXT FM, establish
the connection by touching the last icon with the
stylus.
3. Default login and password are Admin / admin (case
hen the cursor is in a text box, a keyboard
sensitive).

automatically appears. Enter the value and touch
ENTER to validate and hide the keyboard. Additional
characters keyboards are available with the <> key.
Y ncou may also connect in local mode for maintena e
purposes (default password: 1234). Remote connection
is then deactivated.
4. Once connected, the RDS application is displayed.
Default language is English.
5. Should you wish to switch t ch, touch the System
