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 235L Discrete Noise Gate

The API 235L Discrete Noise Gate provides the ability to reduce noise in any program, with emphasis on its fast response, minimizing the chance of losing parts of the sound. When you are faced with (as an example) recorded audio with high volume background noise, the 235L lets you gate the signal at a preset threshold, or using the expander function, reduce the noise to a near inaudible level. The Expander function uses a 1:2 ratio, triggering the signal at the right time without popping or clicking. With its extreme flexibility and superb sound, this unit is ideal for studio use, live sound and a whole range of different applications.

API's Discrete Circuitry

The 235L features API's renowned All Discrete Circuitry, delivering the sonic qualities many would associate with the company's reputation for high quality sound. This unit includes the 2520 op-amplifier and API output transformer. Borrowing components from tried and tested consoles, this unit ensures the highest quality output whilst not compromising on longevity and durability.

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. 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.
