Gear Highlights for Audio Engineers and Producers the Universal Audio 4-710d is a classic preamplifier that has a four-channel microphone/line preamplifier with tube and solid-state tone blending, offering four additional line inputs, dynamics control, and eight channels of pristine analog-to-digital conversion.
belongs to the category of “a must have analogue gear for every studio”. It’s a dream come true for every recording engineer to record through this gear and it is very versatile and flexible and not that complicated to use. You can never go wrong with this gear; vocals, percussions, guitars, pianos etc can be recorded through this classic preamp.
The main feature it has is the mind-boggling blending capability of tube character and transistor character and if blending is not to your taste then you can also go 100% tube or 100% transistor. 4710d also has a built-in 1176-style compressor, including specially tuned “fast” and “slow” settings. This enables quick, on-the-fly tweaking for fattening up a vocal, holding a bass guitar in place, or for adding sizzle and texture to synths and horns.
The 4-710d combines UA’s classic design approach with several modern innovations, creating a unique studio device suited to a wide range of applications. At the core of the 4-710d are four channels of tone-blending “Twin-Finity ” mic preamps with true bypass compression.
Each of the four mic preamp channels allows for continuously variable phase-aligned tone between 100% tube and 100% solid-state. Send and return jacks are available for external processing or signal access.
The eight analogue inputs are digitized via high-quality 24-bit A/D converters at selectable sample rates up to 192 kHz. The digital output is available via dual ADAT “light pipe” or AES/EBU DB-25 connectors, facilitating integration with the most popular audio interfaces.
