Introduction
More than 30 Years of Experience
Delivering the best at all times is not an easy task but the team of SOUND4 makes it seem
effortless thanks to over 30 solid years of experience in the eld. What we excel at, above
everything else, is audio signal processing. Launched back in 2007, SOUND4 began with analog
technologies and went on to achieve groundbreaking results in the digital world as well, having an
instant impact on the market with a string of innovative products. The launch of a set of FM/HD
processing tools was quickly followed by the release of networking audio-over-IP solutions.
2010 was signicant in the company’s illustrious history as SOUND4’s very rst multichannel
voice processor was introduced on the market and the company integrated the Livewire Audio
IP standard, which most of our equipment today is compatible with. This revolutionary product
immediately received the acknowledgement of the industry in the form of two prestigious prizes –
The 2010 Innovation Trophy in Paris and the Pick Hit Award at the 2012 NAB Show in Las Vegas.

a Cool Stuff Award upon its presentation at NAB 2012.
Today, SOUND4 is a household name in the competitive, fast-developing world of broadcasting
technology and enjoys a deserved reputation for proven quality and reliable service.
The SOUND4 – DEVA Partnership
2016 was a landmark year as two of the most respected companies in the industry – SOUND4 and

General Information
SOUND4 IMPACT is sound processing technology at its best. No small detail is overlooked in
this product which delivers innovation, multifunctionality and dependability in equal measure to
produce the consistently loud and clear sound you need. It has a powerful processing chain which
includes 2-band input Automatic Gain Control, based on signal strength and no longer on electrical
average values. It automatically detects differences in levels to smooth out variations in sound
perception. Its structure ensures perfect stability and enhanced vocals combined with a good bass
presence.
The SOUND4 IMPACT introduces an innovative process - mono and stereo parts of the signal
are processed separately to obtain perfect consistency in terms of both sound and level. Therefore,
in moving reception, when the FM receiver switches from stereo to mono and back to stereo,
the sound variations and changes in level are reduced by over 90%. In the SOUND4 IMPACT
processing chain, the stereo expander can be used substantially without any limitations.
With the 6-band processor, a single algorithm guarantees the gain in each of the bands in order
to complete sound stability. “Coloring” is controlled by the Fidelity parameter, which means that it
is possible to have a “purist” and a “colored” sound texture. The 3-band limiter prepares the work
of the nal limiter and is provided with a very powerful algorithm, simplied to the maximum, so
that it is not encumbered with useless parameters.
One of the most signicant features of the SOUND4 IMPACT is the 4-band parametric
equalizer, which is not there to “build a sound” but rather allows some nal little touch-up that
may be required before the nal limiting section.
What is more, this tool has reliable backup capabilities and a number of options. These include
Basic and Full RDS, Streaming Extension, IP TX + RX and Dual IP TX + RX to name but a few. It
can also perform Internet radio streaming and has six fully congurable encoders supporting MP3,
AAC and HE-AAC v1 and v2.
SOUND4 IMPACT comes in a convenient, compact 1U case and has a dual power supply,
which is a standard feature of all SOUND4 In-box products and provides constant, uninterrupted
operation of your unit. Combined with an affordable price and the easy-to-use remote control
interface, this is the ultimate sound processing tool.

Mounting
RACK REQUIREMENTS
The SOUND4 IMPACT mounts in a standard 19-inch equipment rack and requires only 1¾
inches (1U) of vertical rack space. In order the painted nish around the mounting holes to be
protected, the use of plastic washers is recommended.
HEAT DISSIPATION
Having very low electricity consumption, the SOUND4 IMPACT itself generates negligible
heat. The unit is intended for operation within an ambient temperature range, extending from
freezing to 120°F/50°C. But because adjacent, less efcient equipment may radiate substantial
heat, be sure that the equipment rack is adequately ventilated to keep its internal temperature
below the specied maximum ambient.
FUSE HOLDER
The fuse holder is placed inside the unit, next to the voltage selector. Apply downward pressure
and pull the cap outward to access the 5mm mains fuse. The reverse process will release the cap.
