However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 5 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 90 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first two years
  • Claim 50% cash back on the cost of the policy after 5 years if it has not been used!
  • Warranty is transferable if the item is re-sold
  • Loan or replacement equipment will be provided if the product isn't repaired within 30 days
  • If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
  • The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount

Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

The 710 Twin-Finity™ boasts a new UA mic preamp design, combining the classic retro warmth of tubes with the transient bite of solid-state, and all this in a compact 2U, half-rack unit. You can vary the tone blending between 100 tube and 100 solid-state, and use this method to adjust the preamp tone to you're liking, or perhaps discover a tone you hadn't thought of! By combining Tube and Solidstate preamps, the 710 provides you with fantastic tonal possibilities.

Innovative Circuit Design

The 710 Twin-Finity™'s innovative circuit design is key to this preamp's great sonic flexibility. It featuries a solid-state transimpedance input amp simultaneously driving separate, phase-aligned tube and solid-state gain stages, which are then summed to a single output.. Use the "Blend Knob" (labeled "∞") to control the mix between the 310 volt single-ended class-A triode tube stage and solid-state transimpedance stage.

Gain/Level Control and VU Meter "Drive" Mode

Of course, the 710 has dual gain-stage controls (Gain/Level) for you to get customising with. Radically vary the amount of coloration and distortion. You can also see how hard you are driving the input stage with the VU meter's unique "Drive" mode.

It's Versatile! Can Be Used with Electric Instruments!

The 710 boasts great versatility and it features the discrete JFET DI input circuit which can also easily handle any electric instrument. If you're a Guitar or bass player, you'll appreciate the 710s ability to bring out the best of both active and passive pickups. The 710 Twin-Finity also includes a 19" rack-kit for mounting one or two units.


"When pushed slightly into breaking up at a 50/50 mix, this thing sounded awesome on guitar amp... you can even get close to the direct guitar 'Black Dog' tone quite effortlessly with the 710" - Recording Magazine

"UA has made a fun, intuitive, versatile and great-sounding preamp. It can cover many audio bases ... we challenge anyone not to find a use for a 710 in their studio." - MusicRadar
