The SOUND4 BIG VOICE² – 3-Band Processor is powered with the revolutionary HQ-Sound 192kHz Audio Processing engine, a SOUND4 patented technology which has been used for years in other products. Its processing structure includes an advanced DeEsser, 3-band noise gate, Pre-EQ 4-band parametric, 3-band dynamic processor, Post-EQ 4-band parametric, brick wall limiter… Yes much more than a simple noise gate and compressor and we don’t stop there, Big Voice² products offers further enhancements with our own plugin extensions like Reverb and more.

SOUND4 BIG VOICE² processors are flexible, and adapt perfectly to all voices. From Natural tone to Big, everything is possible in a few clicks. The SOUND4 BIG VOICE² is the perfect tool for production studios for that smooth Voice Over.


Dominate-it... Let the lead Talent LEAD!


SOUND4 BIG VOICE² includes the revolutionary “Dominate-It” function so the Lead talent is always the leader. This unique feature invented by SOUND4 gives priority to the main talent and will automatically back off guest mics when the main talent speaks.

SOUND4 BIG VOICE² can even share the “Dominate-It” function with other BIG VOICE² processors to control other mics if needed!


Dedicated to "Live Studios"...


SOUND4 Big Voice² has been designed for Live studio requirements. The dedicated graphical user interface shows 2 Mics, status, affectations and Users Names. Recalling a Mic to a user is done in two clicks… More and more… SOUND4 introduces now the “Session Recall”: it is possible to save all Mic’s affectations + loaded users presets, and then recall all in one click! SOUND4 BIG VOICE² is also externally automatable for dayparts automatic sessions recall…


Bus-Mix… Auto-Mix all mics to one output and save fader space in consoles!

The Bus-Mix function groups selected channel outputs to one physical output. This acts as an Auto-Mix function and is always protected from bus overloads. SOUND4 BIG VOICE² is limited to 1 Bus-Mix and is not sharable with other devices.


Preset Sharing...


SOUND4 BIG VOICE² Preset Sharing function, another SOUND4 invention, offers the ability to automatically share presets with other BIG VOICE² processors across the network. Presets modified in one studio are instantly updated in all other studios. This saves a considerable amount of time and ensures your carefully tuned sound stays consistent no matter which studio is in use.
