OVERVIEW

4 hybrid tube/solid state preamps and 1176-style compressors in a single unit.

The Universal Audio 4-710d is a boutique quality, 4-channel microphone/line preamplifier with unique tube and solid state tone-blending capabilities-perfect for a wide range of microphone and instrument sources. This versatile multichannel preamp offers selectable 1176-style compression circuitry on each channel, plus four additional line inputs feeding 8 channels of pristine analog-to-digital conversion. Building upon UA's classic analog design approach, combined with smart modern features, the 4-710d is the most flexible preamp in the UA lineup.

At the core of the 4-710d are four channels of tone-blending "Twin-Finity" mic preamps with true-bypass 1176-style compression, including specially tuned "fast" and "slow" settings. Each of the four mic preamp channels allows for continuously variable phase-aligned tone, between a 100% tube and 100% solid state signal path. Send and return jacks are available for external processing or signal access.

The eight analog inputs are digitized via ultra high-quality 24-bit A/D converters at selectable sample rates up to 192kHz. Digital output is available via dual ADAT "lightpipe" or AES/EBU DB-25 connectors, facilitating integration with most popular audio interfaces.

Awesomeness!!!!!!! Mind boggling...

Comments about Universal Audio 4-710d 4-Channel Mic Preamp:

Every studio should have one of these!
It is unbelievable how great it sounds!!!! It is just the most versatile pre-amp you will ever find! And for the price... it boggles my mind...
4 Mic/line pre-amps with compressors on each and a limiter for all 8 channels (1176)!!!
I use mine connected to a Motu 8pre, so I am using all 4 Mic channels plus the other 4 instrument channels... Amazing sound possibilities and different configurations with tube... solid state and everything in between!
Superb quality!!!! The sound comes ready!!!!
I can't get my mind around the fact that this is offered at this price...

    Comments about Universal Audio 4-710d 4-Channel Mic Preamp:

    I bought this because of hearing how good the mic pres were and also having the limiting function on the 4 channels. Also it gave me 4 more analog input options for using any pre amp of my choice.
    This gave my set up more options and freedom from before when using an 8 channel optical out put pre unit.
    So far I have been very happy with it! The pres sound great and I love them on the all tube mode but it's nice to have the option of not using the tubes also.
    My go to Pre for bass,guitar, and some drums is the API 3124 but when I compared them it was pretty close especially on direct bass guitar.
    I wasn't planning on using it for vocals since I have a channel strip I am very pleased with for that. But I did try it and was surprised how good it sounded. The pre's alone are a good buy but this unit has some great features I could see anybody finding useful.

        Comments about Universal Audio 4-710d 4-Channel Mic Preamp:

        The UA 4-710d is a very versatile preamp due to its dual topology and added features, which you won't find at this price point on any other preamp of similar quality. If you're looking for a preamp with 4 channels of very high quality, then this is definitely a unit to consider. Your recordings will sound pro, and the DI is really good too!

            Comments about Universal Audio 4-710d 4-Channel Mic Preamp:

            I think it's worth noting, my favorite pre is the U.A. LA-610. This 4-710 sits right above a pair of LA-610's on my rack. There's little to add that hasn't been said about these... they are a no-brainer. I'd immediately replace them if necessary. Very intuitive layout, powerful, warm and present channels.

            This may be obvious to most, but if you're here wondering... This pre's on this 4-sum won't be mistaken for those of their big brothers, the LA-610 MK II or 1176 - but where you don't need that "Special" channel strip, these are more than satisfactory. Very musical and clean. Great job (again) Universal Audio!!
            I can see owning more than one in the near future.

            I'd be 1 more notch above awesome if the comp. was a full ratio knob aside from the "fast / slow" switch... it could be similar and located beside the smaller "FET / Tube" knob. But, that said, the fact that it does have the comp. option and two nice levels at that, is already a plus.

            It's especially useful for tracking mic'd drums.

            If you have no quality pre's, this will give you 4 in one rack.
            If you have top notch pre's and need to fill some gap's these will fill many roles.
