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 3 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 60 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 3 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.

API 565 Discrete Filter Bank

The API 565 Discrete Filter Bank is a 500 series filter module with Highpass, Lowpass and Midrange notch filters. The three filters ensure maximum versatility when it comes to manipulating audio, making it ideal for processing inputs. The individual bypass switches for each filter section let you monitor the sound as you edit filter parameters, letting you turn the filters on and off at your desire. This is a great advantage when it comes to mixing as it enables the user to override filter sections and monitor the sound before and after its been filtered. The classic API analog sound and versatile functionality of this unit makes it ideal for audio professional and sound engineers alike.

The API 500 Series

The API 500 Series focuses on high sound quality and longevity at an affordable price range. Considering most studio rigs undergo a large amount of swapping and changing between equipment, the API 500 series is designed to last, from its high quality components down to its rugged and durable design.

A Brief History Of API

In 1968, The company "Automated Processes Inc." was formed. Best known for their now legendary "2520 amplifier", this unique amp has been and will continue to be the heart of all API discrete products. It continues to provide reliability and sonic purity unmatched by the competition. The resulting console met the needs of the music, commercial and broadcast industry.

API became the leading audio broadcast console manufacturer for radio and television networks and high profile stations. In addition, recording studios, large and small, began using API and receiving rave reviews from engineers and producers. There are over 700 API consoles across the nation and around the world, including the three major networks. Over thirty years later, many of these consoles are still in daily use in some of the most prestigious recording and broadcast facilities in the world because, to date, there are few, if any consoles of equal sound quality at a cost-effective price.
