A revolutionary processing chain...
 

The SOUND4 IMPACT incorporates a unique processing chain with innovative approach which is even described as revolutionary by its first users.

Everybody complain of loudness variation problems between old and new titles. In some cases, the auditor may even feel to switch radio during sequences of Golds and recent titles… This is a concern for many program managers, because a changing sound leads to a loss of identity, and the auditor does not recognize his radio...


With SOUND4 IMPACT you can just forget all these inconveniences, the 2-band AGC is based on the signal strength and no longer on the electrical average values, it automatically detects differences in loudness to smooth out variations in sound perception. Its 2-band structure ensures perfect stability, the vocals are enhanced while ensuring a good bass presence.

Another problem frequently observed in FM comes from variations in perceived levels of reception when the moving receiver switches from stereo to mono and vice versa. These changes affect the tone (loss of treble) but also the overall level of sound perception, so the sound "goes up and down" in addition to a “changing sound”...


The SOUND4 IMPACT incorporates an innovative process: mono and stereo parts of the signal are processed separately to obtain a perfect homogeneity in terms of both sound and level. Therefore in moving reception, when the FM receiver switches Stereo / Mono / Stereo,  the sound variations and changes in level are reduced by over 90%! In the SOUND4 IMPACT processing chain the stereo expander can then be used substantially without restraint.

A 3-band limitation section after the 6-band processing of  dynamics: yet another different choice from all other products on the market. Why only 3 bands ? Just because the outputs of the limiter are added and then feed the final limiter. The facts are simple, the sum of signals on three bands induces less variation in levels than 6 bands. The final limiter job is then more stable and therefore less subject to distortion when the processor is used for very important loudness.
 

On the loudness side, the IMPACT is a real monster, it is able to compete with the biggest market products. The structure of the final limiter consists of 3 limiters: one for basses + one for FM + one for the MPX. This is guaranteed to reach the expectations of demanding managers programs.

An optional IP Audio Codec Solution...
 

The SOUND4 IMPACT has an empowered audio IP transport built-in option which allows to carry audio signals into IP from the studios to multiple transmitters. This option is called SOUND4 IP Connect, and can carry a signal up to 32 destinations!
 
It is possible to re-broadcast a Link to other locations without decoding and re-encoding. Security is at the heart of SOUND4 IP Connect: backup links with automatic switching, multi-gateway to use several modes of transport on the same card, alarm management with SNMP and Alarm Stacker...

A Basic or Full RDS encoder...
 

The SOUND4 IMPACT optionally includes a basic or a full RDS encoder, the latter being compatible UECP. At least the “Basic” RDS allows scrolling PS!

An integrated Audio Backup solution…
Much more than a mere processor, the SOUND4 IMPACT has Audio Backup functionalities. The only limit will then be the capacity of the hard disk to store audio files. It is thus the first processor that guarantees continuity of the On Air program!

Positioning in the product line...

The SOUND4 IMPACT is the biggest FM / HD processing product in PCIe card in the product line.


Concentrate of technology, the SOUND4 IMPACT is a multi-fonction product : besides being an FM processing fireball, it also has several options which are sold 30 to 50% cheaper than external product : Basic and Full RDS, WebRadio Streaming, SOUND4 IP Connect (IP codec), local audio backup… Just make the comparison by adding all these functions as external products + a “big FM processor”, you will get a saving of 30 to 40%!

The
SOUND4 IMPACT is also the first product in the range having unique features that significantly improve FM reception in degraded environments. When developing the product, 100% of the users who participated in the tests in critical environments found a significant improvement in terms of reception, that’s the guarantee to gain more audience in places where frequencies are disturbed.

 

Six Streaming Encoders...
 
The SOUND4 IMPACT is ready for Internet radio broadcast on all media. It has six fully configurable encoders supporting MP3, AAC, HE-AAC v1 and v2. This option is compatible with most popular servers (Icecast, Shoutcast, Flash, Wowza...).


Better yet, this option has the Adaptive Process for very low bitrates (ie: HE-ACC 24kbps). In this case a compensation algorithm corrects in real time the codec in order to lose the least amount of quality: it is surprising to hear, you would not believe it’s very low rate!

Link&Share...
 

Like all PCIe card products, SOUND4 IMPACT is compatible Link & Share. This is a Telnet-like protocol that makes integration easier. 100% of the parameters are externally accessible, it is even possible to create scripts that will be sent by the broadcast automaton to change a PS, change an input in mix mode, change an IP route, an audio Preset... Everything is possible!
