I made some very good sounding records with this. These are actual photos of the unit. Included is everything you need to expand this 4-710d with another 4-710d, giving you a total of 8 inputs via 1 Adat light pipe connection with your interface. I've had up to 5 units (20 preamps) running with no problems using this method. The additional items are 1.
Light pipe, 1 word clock cable, 4 audio patch cables, 1 power cable. The Universal Audio 4-710d combines four 710 Twin-Finity mic pres into a single unit with A/D conversion and costs less than three original 710s combined! But that's not all. The preamps take a Class A FET preamp circuit and a completely separate Class A triode tube preamp and give you the ability to blend the two signals together to taste. While they were at it, Universal Audio also added a simple 1176-based compression section to each channel. Now it's even easier and more cost effective than ever to add a set of these fantastic hybrid preamps to your studio. Phase-aligned "tone blending" of tube and solid-state. Newly designed 1176-style compression/soft-limiting circuit on each mic channel. Discrete JFET DI with 2.2M ohm ultra-hi-Z impedance. 70dB+ of gain, +48-volt phantom power, pad (15dB), phase invert, and low-cut filter (75Hz). Front-panel hi-Z input (switched from mic/line). Rear-panel XLR mic input, XLR line input, and XLR line output. Digital output via dual ADAT optical or AES/EBU (DB-25). 8 channels of high-quality 24-bit/192kHz A/D conversion. Get the best of both modern solid state and classic tube technology with the Universal Audio 4-710 Tone Blending Mic Preamp. The 4-710 features 4 microphone/line preamps with one of a kind tube and solid state blending abilities. Each channel boasts 1176 style compression circuitry with fast and slow settings and can be blended seamlessly between continuously variable phase aligned 100% tube and 100% solid state signal path. It also features four additional line inputs for a total of 8 channels of beautiful analog to digital conversion. This is a brilliant combination of classic and modern technologies resulting in a seamless, feature rich unit. Four TEC Award-winning 710 Twin-FinityT microphone/line preamps. Dual-path 285-volt Class-A tube and transimpedance solid-state preamps. Phase-aligned tone-blending of tube and solid state circuits, creamy to crunchy. Newly designed 1176-style compression circuit per preamp channel. JFET Direct Input with 2.2MO ultra Hi-Z impedance w/auto input override. Large backlit VU meters for flexible metering of input drive, gain level, and gain reduction. 75 Hz low cut filter.
