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 Radial Space Heater has eight channels in four stereo pairs with DB25 or ¼" TRS inputs. Each stereo pair is designed to be 100 discreet, making sure that they can be treated independently or sent to a stereo mix bus. Every stereo pair features its own drive control, adding different amounts of colour. A level control is included to set the output level of the stereo pair. A Heat switch gives the user an opportunity to apply 25, 50 or 100 volts to the valve depending on the desired fidelity. Lower values will attract more distortion while higher voltages will ensure higher fidelity. High Pass filtering is included on all four stereo pairs to help clean up a mix.

To allow for expansion, all eight channels have separate send and receive insert jacks with the send output working as a separate output with the D-Sub allowing for parallel processing. The master section includes a level control, headphone amp, XLR and TRS outputs. The Radial Space Heater is only 1U and fits in any 19" rack frame. An external power Supply is included, accepting anything between 100V or 240V.
