New generation of Audio Processors

The new generation of audio processors FALCON X5 continues in the tradition of quality, reliability and cost effectiveness, maintaining the name Falcon: renowned and valued in the broadcasting environment all around the world.
The new Falcon platform marks a clear break with the previous generation and offers cutting-edge technology that feats the ease of use, exceptional performances and unparalleled sound quality, allowing to generate a modern sound of the highest quality.

FALCON X5 features full connectivity with analog and digital audio I/O (over XLR connectors), 2 independent MPX outputs, USB, GPI and serial ports. The hardware bypass circuit is included in order to guarantee audio presence and programs continuity.

FALCON series has built-in some extra special-features.
The LAN port and the built-in Web Server allow to control the processor and tune audio from anywhere. The built-in digital Stereo Generator ensures an extremely precise MPX Signal. Composite Clipper, part of the Stereo Generator circuit, grant the maximum modulation level, according with the technical rules around the world. This allows each radio station to build their unique sound shape.

The optional embedded RDS Encoder performs a full digital processing, in compliance with RDS 2.0 (UECP SPB490), and provides 2 Data Sets with a wide range of static services, including Radio Text. The logging of output signal is a native feature and give many information about signals parameters. Stored information and time span can be customized and depend on the archiving size of the SD-Card or the USB flash drive.

Audio processing functions are all fully customizable: 5 bands compression control, adjustable drive and threshold, dual bands AGC, 3 bands equalization (Low, Mid and High frequency) and brightness control. The mono sounds phase control allows to give to the human voice a more natural and pleasant sound shape. The final limiter enhances the sound presence.
40 memories allow to recall factory pre-sets or save new one to be restored according to customer needs.

The FALCON X5 processors are equipped with a universal 90-260 V AC power supply, working at 50 or 60 Hz, ready to be used in every country around the world. Due to the low power consumption (max 15 W) FALCON X5  can be considered a “green” equipment.
The FALCON X5 robust design finds substance from the extensive use of steel. FALCON X5 appliances are immune to strong electro-magnetic fields and are suitable to be installed in extreme environments.

A dedicated digital test signal generator can send to all the physical outputs (analogue, digital and MPX) signal sample with variable frequency and amplitude, that helps to calibrate the whole audio system.
The Falcon X Series
Different users have different needs. This is the reason why AxelTech feature a whole processors family with various models suitable for specific workflows. FALCON X7 is the full option version while FALCON X6 is the same model but without the controls on the front panel, suitable to be remotely installed anytime we need to manage remotely the appliance via WEB interface.
FALCON X5, that includes the controls on the front panel, is the cost/effective version of the family.
The new FALCON audio processors integrate, as usual for AxelTech, many accessory features mandatory in the radio workflow – such as the RDS coding (optional) and Stereo Generation – but also looking at the innovative technologies – such as DAB and HD Radio.
FALCON series equipment ensures top quality performances and exclusive audio. It features powerful DPSs, 5-bands architecture, dual bands AGCs, 3-bands equalizer, stereo enhancer, speech detector and 5 limiters. The comprehensive and accurate control of each audio parameter allows to shape perfectly the audio to broadcast unique and exceptional branded sound.

Signal Routing and Changeover
The new FALCON processor is able to switch between any available source: Analog, Digital, MPX, AoIP…
It’s possible to add up to 10 seconds delay to MPX output to synchronize DAB signal (connected to analogue or digital output) to FM signal connected to MPX output. An embedded Test Signals Generator allows to output an audio signal suitable for testing the equipment or the whole audio system.

I/O Connections
FALCON Audio Processor new series features a complete set of input and outputs connections. Analog and AES/EBU digital audio connections are standard aside of two buffered and independent multiplexed output (MPX RDS) whit hardware bypass.
Analog Input > Analog Output | Digital1 Input > Digital1 Output | MPX1 Input > MPX1 Output | MPX2 Input > MPX2 Output
Three USB ports (one on the front, one on the rear panel and one installed on the internal circuit board), are available.
microSD allows to clone the whole setup from one Falcon to another one.
Two AUX inputs (SCA) allows to connect an external RDS encoder. Another AUX input can receive the audio from another MPX processor and switch with the internal generated MPX, allowing to build a small network managed from radio automation system. Connection setup includes a Dante license that allows to manage AoIP Dante or AE67 signals: 4 inputs and 4 outputs.

Front Panel
FALCON X5 features a wide LCD monitor, TFT Technology (480×128) that shows the input and output processing, including the corrections for each band featured from the compressor, the limiters and the multiband AGC.
Obviously it shows also the input and output of all signal levels.
Moreover trough the display it’s possible to check the system status: operating parameters, GPI/O port status and RDS parameters, including the station’s ID.
A TRS (stereo Jack 6,3 mm) connector allows monitoring both original and processed signal, checking in the faster way the differences between the available pre-sets.

Communications & Alarms
FALCON audio processors can exchange information with other equipment through some communication ports:
One LAN/WAN port, two RS-232 serial ports, two USB ports, one GPIO port with optical coupler and relays.
Information will be sent (status, alarms) or received (commands).
A panel with 40 LEDs (the LCD panel in the bigger model) shows status information.
Alarm messages can be sent via GPO, SNMP (Trap), http and email.

Web Server
Users can manage FALCON equipment via LAN, no need to install any client software.
The internal Web Server can be managed with any browsers (Chrome, Firefox, Explorer, Opera…). The GUI on the web page is clear, easy to use and responsive, suitable to be managed from any device: Personal Computers, tablets, smartphones.
SNMP (v 2.0) programming protocol allows to manage the whole command set.

FALCON firmware implements also HTTP, FTP, SNMP, SMTP, UDP, TCP and is PV4 – IPV6 addressing compliant. RDS services need a precise synchronization: the system tries to connect to a primary NTP, backup NTP and to an external GPS receiver (not supplied).
Moreover connecting an external GPS allows to geo-localize the FALCON. The WEB server supplies a page with a map that shows the appliance position.

Standard Ethernet interface can manage up to 4 independent TCP ports, up to 4 separate UDP ports and 1 SNMP port. Obviously, it shows also the input and output of all signal levels.

MPX Stereo Generator
The stereo generator integrated in the DSP structure, provides an almost ideal MPX signal, optimizing the performances of the equipment to the maximum.
All of the parameters for pilot level, phase and levels are adjustable via the web page.
Stereo Generator circuit can switch the source between the internal MPX and an external signal. Switch can be managed locally or with a command sent by an external radio automation software via Ethernet or GPI.
RDS Radio
Data System Encoder (Optional)
FALCON RDS embedded circuit is compliant with the latest standards:
UECP EBU SPB490 v7.05, Cenelec (Europe) and NRSC (USA).
The new “dynamic” feature allows to manage many kinds of services:
Connecting the RDS with the radio automation software it can show many kinds of information: song title, song artist, on-air program, speaker’s name, etc.
The native interface with RSS feed format (RSS 2.0) allows receiving directly news feed

The internal RDS embedding give more advantages:
> Allows to remove a separate appliance from the transmission chain
> Concentrate the control of all the broadcasting parameters just in one equipment
> Raise the output signal signal/noise ratio and stability
> Remove all the locking problems between the pilot phase and the RDS carrier phase
