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 SR 40 Mini Receiver provides three status LEDs indicating ON/OFF status, received signal strength (RF OK) and audio clipping (AF CLIP). The VOLUME control sets the level at the 1/4" output jack. The supplied switched mode power supply operates on any AC voltage from 110 to 240 VAC and includes EU, UK and US adapters.

The PT 40 Mini bodypack is probably the smallest and lightest transmitter in its class. A reliable mini XLR output allows you to connect every compatible AKG miniature microphone. Battery life of the transmitter is the same legendary "30 hours off a single AA battery" as for the WMS 40 models, reducing the need to replace batteries and thus saving real money in the long run.

The system includes an SR 40 mini receiver, a PT 40 mini pocket transmitter, an MKG L instrument cable, a universal power supply with US/UK/EU adapter and one AA size dry battery.
