SOUND4 PULSE Eco 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 PULSE Eco 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 PULSE Eco processing chain, the stereo expander can be used substantially without any limitations.
With the 3-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 final limiter and is provided with a very powerful algorithm, simplified to the maximum, so that it is not encumbered with useless parameters.
One of the most significant features of the SOUND4 PULSE Eco is the 4-band parametric equalizer, which is not there to “build a sound” but rather allows some final little touch-up that may be required before the final 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 configurable encoders supporting MP3, AAC and HE-AAC v1 and v2.
SOUND4 PULSE Eco comes in a convenient, compact 1U case at affordable price and the easy-to-use remote control interface, this is the ultimate sound processing tool.
HQ Sound, main sampling process frequency of 192 kHz.
Others key points:
The SOUND4 PULSE Eco has four inputs - Digital, Analog, IP (Livewire or SOUND4 IP Connect) and PCI.
On the software interface, the input currently in use is indicated by a triangle on the left side of its name.
With the SOUND4 PULSE Eco, the first processing function is the 2-Band AGC - automatic gain control whose main purpose is to stabilize the loudness level applied to the input of the processor and prevent noticeable level differences between recent and old titles.
The Tone FX makes coloring of sound before dynamic processing possible. To do so, it groups together two types of processing functions:
The two functions offer results that are entirely different, which is why they are gathered on one single screen.
In Basic mode, use of the four parametric equalizers is simplified to the maximum. Only the gain for each correction is accessible. For FX Bass and FX Treble, dosage of the effect is also made accessible.
In Advanced mode, users have access to all equalizer parameters (gain, frequency and Q factor).
SOUND4 PULSE Eco has a true stereo enlarger, 100% mono-compatible. Its role is to sublimate the existing stereo image. It will thus never create stereo in mono sources.
In addition to embellishing the stereo image, it also has a 3-band stereo image limiter acting on the control of the energy transmitted by the stereo sub-porter at 38 kHz. This unique functionality limits issues currently caused by the traditional enlargement processes. The stability of reception in areas disturbed by multiple routes is thus greatly optimized.
The 3-band Process is the heart of dynamic processing. With SOUND4 PULSE Eco, a single algorithm guarantees the gain in each of the bands in order to complete sound stabilization. “Coloring” is controlled by the Fidelity parameter. Thus, it is possible to have a purist and a colored sound texture.
The 3-band Process is achieved through the revolutionary algorithm S.I.S. (Sound Impact System), which makes it possible to maintain the authenticity of the original sound attacks.
The main purpose of the 3-band Limiter is to prepare the work of the final limiter. It is also provided with a very powerful predictive algorithm, which has been simplified to the maximum, so that it is not encumbered with useless parameters.
The parametric 4-band equalizer is by far the most impressive feature of the SOUND4 PULSE Eco. It is not there to "build a sound"; it allows some last little touchup if necessary before the final limiting section.
In Basic mode, use of the four parametric equalizers is simplified to the maximum. Only the gain for each correction is accessible. For FX Bass and FX Treble, dosage of the effect is also made accessible.
In Advanced mode, users have access to all equalizer parameters (gain, frequency and Q factor).
The Final Limiter comprises two sections - one for FM applications and one for HD applications.
The FM Section consists of a Bass Clipper, guaranteeing powerful bass without distortion, an FM limiter and an MPX limiter.
The HD Section is specifically designed for high quality digital applications (HD/DAB/DRM). This is a look-ahead type of limiter and in this mode the outputs are not limited to 15 kHz.
The outlets of SOUND4 PULSE Eco are fully assignable. For example, the analog outlet may replicate the signal which is applied to the analog input, the digital outlet delivers an HD signal, the TX1 outlet delivers the MPX signal and the TX2 outlet drives the 19-kHz pilot signal.
