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.

PRX800 Series

PRX800W is the first series of PA systems in its class to offer complete wireless control. The innovative PRX Connect app for iOS and Android devices connects wirelessly to each unit in the system simultaneously, providing you full control over the sophisticated built-in DSP. Offering control over an 8-band parametric EQ, speaker delay up to 50ms, mute, gain and much more, the PRX Connect allows you to achieve the perfect sound faster than ever before. This also provides you with the ability to walk around the venue during sound check and fine-tune the speakers to ensure optimal sound quality. PRX Connect also makes it easy to configure shows offline and save presets for instant recall in the future.

Next-Generation Technology

The JBL PRX815XLFW features the patented JBL Differential Drive® technology which reduces magnet mass and increases the power handling capabilities, while the updated tuning delivers flat frequency responses and smooth off-axis behaviour. At the core of the input section is the incredibly sophisticated and powerful DSP, which features user selectable system EQ, protection, input sensitivity selection, cross-over functionality, dynamic limiting and discrete component optimisation.

Professional Quality

All PRX800 cabinets are built from a combination of 25mm (on the top and bottom for addition rigidity) and 18mm lightweight plywood, with incredibly strong tongue and groove joints. Additionally, the cabinets are finished with JBL's tour-proven DuraFlex™ finish which provides additional durability. The grilles are made from a dent-resistant 16 gauge steel while all M10 mounting points are constructed from 14 gauge steel and have been tested with a yield-strength of 1000 lbs each.

''With the PRX800W family, we're excited to give bands and DJs more control over their live sound than ever before. Users can now shape their sound wirelessly, right from the palm of their hand, ensuring the best possible listening experience for themselves and their audiences. PRX800W is by far our most advanced and portable PA, and represents the next generation in smart live sound reinforcement.'' - Craig Lambrecht, Retail & Recording Solutions, HARMAN Professional Solutions.
