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.

PreSonus HP4 4 Channel Distribution Amplifier


The HP4 from PreSonus answers the project studio owner's needs for headphone distribution with professional specifications and more in a small package with an affordable price. The unit comes in a 1/3-rackspace chassis similar to the TubePre. The HP4 accepts balanced/unbalanced inputs and outputs (1/4" TRS). The input can either be set to stereo or mono. The mono selector button on the front channel simply copies both inputs to both sides.

Small yet versatile

Ideal for a modular setup with PreSonus' other popular compact units (TubePre, Comp16, and EQ3B), the HP4 comes packed into a 1/3-rackspace chassis that's super-efficient, durable, and frankly, cool-looking. Its small size is deceptive: you get an incredible amount of functionality and versatility out of this unit, making it perfect for your individual setup!

Four headphone outputs

The HP4 has four headphone outputs on the front panel each with its own volume potentiometer and 250mW of amplification per channel. For such an affordable unit, you get a great monitoring tool for any studio application.

Ultra-quiet, ultra-controllable

The HP4's -98 dB noise floor and wide frequency response enables it to be ultra-quiet. The HP4 allows control over control room monitors with a separate volume potentiometer that can be muted using the MONITOR MUTE button. The HP4 is powered by an external wall mounted power supply.
