The product price includes a one year warranty and 30 day money back guarantee.

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 dbx 286s is a microphone pre-amp channel with five dynamic processors which can be used independently or in any combination. Why mic up vocals and instruments through a noisy, blurry mixer? The dbx 286s is equipped with a sonically pristine mic pre-amp including all the features you need- a wide-ranging input gain control, switchable 48V phantom power and an 80Hz high-pass filter. Use the 286s features the patented OverEasy compressor to transparently smooth out uneven acoustic tracks or deliver that classic "in your face" rock vocal. Take out vocal sibilance and high frequency distortion in cymbals with the frequency tunable De-Esser. Fine-tune the Enhancer's HF Detail control to add sparkle and crispness to tracks. LF Detail control adds fullness and depth to vocals and bass instruments while simultaneously cleaning up muddy low midrange frequencies. The Expander/Gate provides separate threshold and ratio controls allowing you to subtly reduce headphone leakage or radically gate noisy guitar amps.

The dbx 286s has a full complement of metering and status LEDs, visually guiding you to achieve the right sound. A XLR mic input accepts balanced or unbalanced inputs, whilst an additional 14" TRS phone jack can accept balanced/ unbalanced line signals to process live electronic instruments or pre-recorded tracks at mixdown. An insert jack between the 286s mic pre-amp and signal processing sections can be used to "loop out" to external processors (such as EQ) or to mix the pre-amp's signal out to an external destination.

The cost and hassle of patching together multiple processors for use on one track can be frustrating. The dbx 286s gives you all the tools you'll need in one box, with the shortest signal path to help keep your music sounding clean.
