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.

Portable Phantom Power Solution

Designed to be used in conjunction with the AKG MicroMic series this portable Phantom Power supply allows you to record wherever you are. The unit is powered by two standard AA batteries, which produces a performance time of around 30 hours. The unit features two mini-XLR-F inputs (L and R) ensuring optimal audio quality for up to two microphones. Both inputs can be switched to either mono or stereo for use with a range of different microphones. The output on the B23L is a standard 3.5mm stereo jack, allowing you to connect the power supply to a range of devices.

Mini-Recording Mixer

As well as being a versatile phantom power supply, the B23L functions as a mini recording mixer. There are two separate volume controls that allow you to set the level of each microphone independently. This feature is ideal to differentiate between two audio sources such as voice and instrument signals, allowing you to adjust the volume of each source independent of the other. On the rear panel there is also a metal clip, that allows you to attach the unit to your clothes or other things to increase its portability.
