Axel Tech Falcon X6 FM/DAB+/HDRadio/WEB/DRM Digital Audio Processor

The new generation of AxelTech audio processors 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 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 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 can be considered a “green” equipment. The FALCON robust design finds substance from the extensive use of steel. FALCON 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.

Highlights

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.

The new “dynamic” features allow to manage many kinds of services:
PS, RT, RT+, PTY, PTYN. Connecting the Falcon with the radio automation software it can manage many
additional information such as song title, song artist, on-air program, speaker’s name, etc. The native
interface with RSS feed format allows receiving directly news feeds and it is RDS 2.0 ready.
REAL TIME AUDIO MONITOR
Processing delay is quite non audible and depends on the processing complexity.

Audio Processing
Clarity of sound
FALCON processors high-quality hardware design and software algorithms produce a detailed, crystal clear sound on any speaker system, always preserving original audio signature.
Voice processor
A dedicated processing section boosts presence of voice delivering a soft, silky sounding effect. Vocals are always on top of the mix making lyrics comfortably audible. Each instrument and vocalist gains dominium of its own space.
Extreme density
FALCON processors deliver full impact sound at the highest volume density preserving original audio detail, identity and mood. The dedicated ‘Bass Enhancer’ stage delivers a strong and effective ‘drum punch’ for a deep musical emotion.

And then you can extend these presets by adding new families and variants

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.

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 
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:
PS, RT, RT+, PTY, PTYN.
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
