Sounded Pretty good...When it worked

I had this for 6 months and it spent about 2 months in the shop. 1st trip channel 1 had a drastic (~15dB) Difference at same settings Sent to sweetwater for repair. 2nd trip about a month later Meter Failure followed by Loss of channels 1 & 4. Sent to UA for repair and promptly sold. I really liked it when i had it but i was so discouraged by all the fixes that i just bought a 2nd apollo instead. Do yourself a favor and just get a 2-610. I liked all the features on the unit, the compressor the extra converters the tube transistor knob but it just didn't work.

4-710d Four-Channel Tone-Blending Mic Preamp w/ Dynamics

Beautiful sounding preamps from clean to mean. The wide tonal range available allows full control of harmonic content and character. Simple dynamics controls work well on all types of sources. Converters sound fantastic and have an analog vibe that is full, with a tight low presence, detailed mids, and bright high end that is pleasing and never harsh. This is one of the best deals available on the market. 4 Preamps w/ dynamics and 4 Inserts for a total of 8 channels of AD conversion on DB-25 or ADAT! Definately a lot of bang for the buck and an outstanding unit.

Four fantastic preamps and 4 inserts of UA A/D Conversion is a fantastic deal!

This 4 Channel preamp allows a blending of Tube & Class A in the preamp to taylor to your liking and source material. Has "1176" style flavored Dynamics on each channel w pad / phase / 48V Phantom and 2 settings for compressor. Features 8 channels of excellent A/D conversion up to 192, 4 for preamps and 4 as inserts you can use for other studio equipment. (At 192 only 4 of the 8 channels work) This unit is worth twice what they are asking for it! Preamps are the 710 and sound great on all sources. I start in the Class A side and blend in the tube warmth and character needed. If you put it all the way to the tube side you will notice the noise floor, though class A side has negligible noise. I have used the inserts for converting many sources and the converters sound warm and musical. I really like the built in compressor when recording electric guitars or ambient / Room mics. The pre also really shines on vocals. I bought mine when they were offering a free Octo-Core which helped me decide to pull the trigger. Even without it, it would have been an excellent purchase for what I feel I received. A studio full of these pres really would need no others.

Versatile and powerfull machine!!

This preamp is a really good choice if you need more channels with great quality in your studio.
The sound could be transparent if you want, and you can also feed the tubes and get big warm sound. It is very versatile-
Having an 1176 compressor on the chain is one of the greatest features of this machine. It is a dream to have 4 channels of an 1176 ready to use. Having 8 AD converters with the quality of UAD makes this unit even sexier.
If you need only one channel look somewhere else. Like the 610 or another brand. But if you need more than 2 channels with great features this thing is hard to beat.

I love my 4-710d. Use it to record everything and get great sounds every time. The compression is fantastic as well and the quality of the A-D conversion is stellar. I've recommended this box to several friends who've all had similar results in their studios.

Over the top blowing masters!

Well, recently aquired, i'm very happy with results. Reaching amazing depth and consequently masters sounding high as hell blowing your tympanus with overall V.U. halfway up... Not to mention the clarity of the sound... Stoked! I recomend...

Ultra clean and trasparent mic pres

it's no secret in my circle of peers that I'm a big UA fan. These jewels have plenty of head room for those high output condensor mics. When you compare these units to other high quality mic pres that are mostly either single or dual channel units you get way more bang for your buck with the 710's and you don't have to sacrifice quality either .

Box of Magic !

I use this as a front end with my Apollo for its inputs and ADAT Inserts - total lifesaver with its built in 1176 style comps and digital converters

These preamps sound fantastic and the versatility they provide leaves you with immense options. Works great as analog preamps or wonderful addition channels to my apollos via adat optical output.

It is a great blend of the clean and the soulful ways of the sound. It compliments very well my Apollo and Apollo Twin set-up. I am using it slaved via WordClock as the ADAT sync proved a little unstable. The extra 4 line ins that can be also sent via ADAT ara a great addition. The blend know is fantastic, the compressors too. I use it all the time :-)

Very very versatile and great sounding unit. Lots of timbral possibilities. The extra 4 audio inputs is great for expanding with external mic pres. I prefer clocking it via word lock from my Apollo unit as the overall stability and sound quality seem to be better. I was getting some pops over the Adat sync. I would recommend it as a natural expansion unit for any Apollo or Apollo twin set-up.
