The SOUND4 IMPACT - PCIe Card has no competition among the FM/HD processing PCIe-card-based tools not only in the SOUND4 product range, but also on the market all over the world.


An innovative solution based on the latest technological developments, the SOUND4 IMPACT is a multi-functional product of advanced capabilities. Besides being a cutting-edge FM processing tool, it also provides a number of options whose price would constitute a 30-50% price increase if offered by a separate product, such as Basic and Full RDS, WebRadio Streaming, SOUND4 IP Connect (IP codec), local audio backup. The SOUND4 IMPACT effectively combines performance with cost-effectiveness to make it the smartest choice on the market.


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, all of the users who participated in the tests in critical environments found a significant improvement in terms of reception, which guarantees a larger audience in places where frequencies are disturbed.


A Unique Processing Chain

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

A common problem users report is related to loudness variation between old and new titles. In some cases, the auditor may even decide to switch the radio station during sequences of old and recent titles. This is a concern for many program managers because a changing sound leads to loss of identity, and the auditor does not recognize their radio.

With SOUND4 IMPACT, all these inconveniences are a thing of the past. 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 structure ensures perfect stability and enhanced vocals combined with a good bass presence.
