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.

Audio Technica BP40 Large-Diaphragm Dynamic Broadcast Microphone

The Audio Technica BP40 Large-Diaphragm Dynamic Broadcast Microphone delivers natural condenser-like sound with clear and articulate reproduction. Perfect for a variety of applications including radio, overdubs and post-production, the BP40's patented floating-edge construction promises to maximise diaphragm surface area and overall diaphragm performance, while the humbucking voice coil prevents electromagnetic interference. When working in close production environments, the hypercardioid polar pattern provides isolation of the desired sound source and off-axis rejection. The microphone’s design, inspired by the visual representation of a waveform, features rugged, all-metal construction for dependable use in professional broadcast environments. The BP40 comes standard with the AT8483 mounting clamp.
