With the VOICE ULA2, SOUND4 has developed a cutting-edge product to meet the strictest customer demands in terms of affordability, design and functionality.
Universal Lan Audio Version
Although the SOUND4 VOICE exists in several versions, the Livewire & RAVENNA compatible version deserves special mention as it is the first multichannel voice processor 100% compatible with all Axia and RAVENNA products.
Livewire* is the audio-over-Ethernet standard created by Axia Audio that provides easy routing and sharing of broadcast-quality audio. "Everyone agrees that IP-Audio is the future. There are already more than 1,500 studios around the world powered by Axia Livewire networks," says Axia Vice-President Marty Sacks. With the Livewire* system, a single Ethernet cable carries in real time all mics, as well as uncompressed digital audio, device control messages, program-associated data and even routine network traffic. One of the advantages of the SOUND4 VOICE ULA is its capacity to work as a resource that can be routed and inserted anywhere in the Livewire* chain.
An especially cost-effective solution, the SOUND4 VOICE ULA will catch your Mic ID (from nodes or mixers), process separately each channel and then send it back to the mixer on a new ID.
Much more than a simple combination between a noise gate and a compressor
SOUND4 VOICE ULA is powered by the revolutionary HQSound 192kHz Audio Processing Engine – a SOUND4-patented technology.
Its processing structure includes an advanced DeEsser, a 3-band noise gate, a 3-band processor, a 4-band parametric EQ, as well as a brick wall limiter. All those features make it much more than just a combination between a noise gate and a compressor. SOUND4 VOICE ULA is flexible and offers impressive adaptability to all kinds of voice. A wide range of possibilities is at your disposal – from natural to loud and structured, all tones can be achieved in just a few clicks.
Due to its advanced set of features, the SOUND4 VOICE ULA is also the perfect solution for production studios.
A Voice Processor Dedicated to Live Studios
A stand-out new feature that our team introduces with the SOUND4 VOICE ULA is the “Session Recall”. It allows you to save all Mic affectations and loaded user presets, then recall all in one click. SOUND4 VOICE ULA is also externally automatable for dayparts automatic sessions recall.

The SOUND4 VOICE ULA2 can process separately up to 2 microphones.
Thanks to the Multi-Studio mode, a SOUND4 VOICE ULA can distribute resources over several studios. This means that if a user has two studios to equip with three microphones each, a single SOUND4 VOICE ULA2 provides an easy solution due to the fact that it can function as two processors, operating separately for each studio. Moreover, studios can Save and Recall their own sessions.
In-House User Presets Centralization
This function facilitates work in multiple live and production studios. As long as there is a SOUND4 VOICE ULA in each of them, animators, interviewers, journalists and DJs will have access to their own presets in each studio.
If a User preset is modified from one studio, thanks to the “in-house user presets centralization”, all other studios will be automatically updated.
SOUND4 VOICE ULA2 offers the possibility to create a preset for each user. Usually, sound processors are running with the same level adjustment. Due to its one-of-a-kind preset function, however, the SOUND4 VOICE ULA2, sound level can be adjusted and the following basics can be adapted depending on the user:
- Input Gain
- Output Gain
- Output Mode - independent or grouped in a bus mix (2 bus mixes are available in SOUND4 Voice ULA)
- Phase Invert and Phase Rotator
- Low Pass & High Pass Filters
- 3-band frequency adjustment
In SOUND4 VOICE ULA, the De-Esser tracks automatically the sibilance frequencies, the user just needs to set up the gain attenuation and the Q Factor which defines the correction width.
One the left side, a graph shows the De-Esser working in real time.
3-Band Noise Gate
In broadcast voice processing, Noise gate is a crucial functionality for general voice sound optimizations. Thanks to HQSound algorithms, the SOUND4 Voice ULA Noise Gate is extremely reactive in opening and closing Gates. This is a real advantage compared to major solutions on the market which usually "eat" the first syllables.
The 3-Band Process
The 3-band Process is the heart of dynamic processing. The SOUND4 VOICE ULA 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.
Advanced mode allows access to "Smart Gate Threshold", Ratios, Fidelity, SIS, Drives, Thresholds, Attack Time, Release Time and Mix Output Gain.
The 4-Band Parametric EQ
The Parametric EQ provides the final touch in a sound setup. The SOUND4 VOICE ULA is powered with a 4-band parametric Equalizer.
Advanced mode offers access for each band to Frequency, Q factor and Gain correction.
The Brickwall Limiter
The Brickwall Limiter is an advanced algorithm which provides strong gain limitation, guaranteeing that there are no overs and no clipping.
