Classic tube and solid-state tones with 1176-style compression and professional A/D conversion.

By merging the best of UA’s classic analog design with smart modern features and workflow enhancements, the 4-710d is the most flexible microphone preamp in the UA lineup.

Featuring four high-end mic/line preamps with a unique tube/solid-state tone blending circuit, as well as classic 1176-style compression on each mic channel, the 4-710d also offers tons of digital I/O to expand your setup.

Track through meticulously designed UA tube preamp circuitry

Blend tube and solid-state textures for tons of flexibility

Harness classic 1176-style compression on each mic channel

Add 8 inputs to any Apollo interface via ADAT optical connection

Bring your Mic Collection to Life with a Wide Range of UA Preamp Tones

Bring your Mic Collection to Life with a Wide Range of UA Preamp Tones

At the core of the 4-710d are four channels of tone-blending “Twin-Finity” mic preamps. Each channel offers 100% tube and 100% solid-state signal path, as well as the ability to continuously blend between the two circuits. This gives you tons of textures — from creamy to crunchy — and lets you dial in the perfect amount of tube grit or solid-state sheen.

A Legendary Compression Circuit

A Legendary Compression Circuit

Each of the 4-710d’s four channels features true-bypass 1176-style compression, including specially tuned "fast" and "slow" settings. This enables quick, on-the-fly tweaking for fattening up a vocal, hold a bass guitar in place, or for adding sizzle and texture to synths and horns.

Add Inputs and Professional A/D Conversion

SUPERB

The 4 preamps are good, the 1176 style comps are very useful and easy to set up. I really like that it has 8 channels of analog to digital converter with optical adat connection, so I can send another 4 pres to my interface. I use it on drums and percussion, acoustic guitar, choir, some vocals. Superb!

I miss these converters!!

For 2 years I had this as my primary DAW front end & I LOVED it. The converters were much nicer than anything else I used prior & just as nice as anything since (MOTU, API, Antelope). The preamps were good, clean, useful on anything. I would be content using them on everything & often did. I didn't find the sonic difference between the SS and the Tube sides all that different (grains of sand, really) but it was nice to have that blend knob to find the perfect tone. I miss the limiter before the digital stage. I miss the 1176 clone compressor built in. I have 17 channels of pre's I wish were these units instead! I only sold this unit because someone offered me "New" value at a point I wanted to invest in some really nice Pres (la610 too).

Breaths new life into microphones

The 4-710d has truly brought all my microphones to life! The blend knob really helps dial in the tone and adds great character to each capture. Can't recommend this pre-amp enough!

Versatile

I picked it up used out of Nashville used and, I will be purchasing another as, I complete my gear acquisitions for the studio I'm building. I wired it into the signal path using an Apollo Twin into Cubase. Set up was easy and, intergration was seamless and hassle free. I demoed it by plugging a P-Bas straight in and it ROCKED! I then used multiple mic situations! I plugged a tube mic in and ran it heavy to the transiter side and had plenty of headroom and tube love! I then plugged up a TLM-49 and the sonic range was borderline staggering! And then, "just to make sure" I put a SM-57 and a AEA ribbon mic in front of a 50 watt Marshall!...........YEP! ......Buy it Fool!

yes, but

why does the apollo (dual/quad, not 16) not have an AES/EBU port?? I mean seriously, this would make 100% sense and they would sell A LOT more Apollo/4-710D Combo Packages... It's just stupid... sorry. ADAT is not "the same".

One star off for "made in china" - it does not feel as solid as the usa built stuff. Can't say anything about the duration so far. One year in use and not a single problem at all.

Accurate with character, incredible range of features.

The UA-4710D is not only incredibly flexible and feature packed but quality is top notch, no sacrifices made here. Clean gain available all the way to 10.

Nothing New to Report. It's Excellent

Sometimes the skies part, a beam of light comes down, and a great piece of gear lands at your feet. Or, you go to a website and order it. Either way, most will be thrilled with the 4-710d. You're just not going to find a group of four preamps that sound this good at this price. Beyond that, being able to blend between transistor and tube opens up creative possibilities that aren't readily available elsewhere. I like to go in direct with my Les Paul and then run it to my Apollo for effected guitar sounds that no one else can dial up on pretty much anything. I also route out of the Apollo into it to add tube warmth to software instruments and haven't even touched the surface of the ideas that started rolling in once I got to playing around.

Wow, what a great multifunctional unit!

Super great product!
1. Really nice sounding preamps, that can be driven really hard if desired, with both the solid state and tube sides emitting a really nice range of distortion.
2. Actually very functional compression on each channel, with the two important main choices available...smashed fast square edge as well as smooth soft knee 1176 styles. Wow, these really work!
3. Balanced line inputs...with resulting pretty great harmonic and compression options on mixdown(!) as well as pretty great translation of synth and other non hiZ instrumental signals.
4. Really sophisticated A/D conversion, with (!) four additional inputs for other sources, with optional pre converter limiting.
5. And it all really works well! Great job UA!

Awesome! Great Options at a great value!

I tried this for the 1st time after buying a friend the single unit. I was blown away with how vocals sound on it. For the money you can't go wrong. The converters sound good and it was a nice way to pair a great converter for my Apollo Twin. I can now use my custom gear with the awesomeness these two products hold. Thanks UA for the free Quad Card!

Still waiting for the unit to return from warranty repair

One of the gain reduction meters were not calibrated correctly and therefore was not working. This was very disappointing. Support team did not even apologise for this oversight and directed the unit to an authorised repairer. I bought two pre amps and the one I do currently have works wonderfully

Welcome back Analog!

What a treat to hear such warm creamy or hot fuzzy textures from my modular synths or human vocalists and have them perfectly preserved in digital! This is now my go-to preamp. Thank you UAD!

True Hybrid

You really can't go wrong with this unit. Really well thought out for today's Analog/Digital world. The converters are totally usable, I have Lavry converters to compare them. I feel they have some color, work well coming off the 710 pre-digital out. I like it, very, Rockn'Roll. The 1176 chip on each channel just faten's things up even more, killer for vocal mics. Transparancy is also achievable by turning the blend knob to the far left and lowering the gain to minimum.
Making things simple, the channel strips are easy to use, very dumby proof. You don't need to know much to get a great sound. Read the manual, nice options for routing, really handy insert on/off switch, and a whole lot more!

Love It!

Perfect pair with an Apollo Quad for me. Even alone, it has so many options and is such great value. Well done UA

Fantastic pair to the Apollo!

While this unit indeed can easily stand on it's own, I've found it to be a dream when paired with an Apollo quad. Boom, this baby, the Apollo, a UAD satellite and a host of plugs have completely streamlined my workflow and enabled my set up to be as mobile as it needs to be.

the 4-710d is a bargain for the pre's alone and the palate that can be dialed in with them. Add in it's high end clocking and the compressor options and you get even more. The send/insert options as well as all the phase inversion options on each channel make this pre amazing, and a great value as well.

I don't know why I waited so long to buy this unit... It is absolutely brilliant and a no-brainer to use... It just makes everything sound better...

4710 D

What can i say a truly awesome unit!

As with all UA equipment this thing oozes build quality and sturdiness. I use mine on the road and have no fears.....

The manual is really very helpful and thorough without needless technical jargon for those of us who are not robots.

The preamp / blend control is certainly the highlight of this unit , offering an array of coloration from ultra detailed clean to darker tones.

the input, output, gain reduction switching on the vu is very helpful and the 1176 style compression although perhaps a little limited has really worked for me on certain applications such as drums and acoustic guitar.

would i buy another ? WITHOUT A DOUBT

Excellent DAW front end

Perfect for the front end of your Digital Audio Workstation as an audio input. The 4-710 includes four amazing mic press, compression and AD, plus an additional four AD converters and clip limiting. The ability to choose between tube, solid state or a blend gives some nice choices for recording. The DI's sound great as well. I found tracking an electric guitar track recently quite enjoyable with recording the DI signal with slight tube distortion along with three other mics for tonal variety. In the end, I used all four channels for most of the tunes on the album. Having the different channels allowed me to adjust later to the songs mood. I never thought previously that I would need four channels for tracking guitar!
