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 ADL700 preamp has maximum headroom thanks to its Class A, discrete design that makes use of two 6922 and one 12AT7 vacuum tubes that operate with ±300V power rails. The ADL 700 also has a dual transformer design that ensures low noise operation with maximum common-mode rejection. This PreSonus preamp is housed in a 2 rackspace rugged steel chassis.

PreSonus's ADL700 preamp includes an input select switch that enables you to keep all 3 inputs (mic, line and instrument) connected at all times whilst the mic input has a choice of 4 impedances. This unit also provides you with variable input gain that uses an 8 position switch that can provide 35 dB of gain in stepped 5 dB increments. The final preamp stage can be adjusted by a trim potentiometer.

Also onboard the ADL700 is a compressor that includes a fully variable attack, release, threshold, ratio, makeup gain and bypass controls as well as a 'soft knee' compression curve. 2 separate units are able to have their compressors linked to achieve precise stereo compression.

The 4 band parametric EQ combines isolated filters and optimised per band Q that provides subtle signal-shaping without harsh artifacts. All the bands feature 16dB of cut or gain and frequency controls, with overlapping frequency ranges and fixed bandwidth. The low and high bands are also switchable between shelving and peak.

The EQ position in the signal chain can be switched to either pre- or post-compressor and front panel switches can bypass either or both. Phantom power is available, as are a 20 dB pad and polarity reverse. Fast-acting, eight-segment LED meters accurately detect fast transients and peaks. Large, back-lit, dual-mode analog VU metering enables monitoring of output and gain-reduction levels. A -6 dB switch offsets the meter for use with hot source signals and a master level control adjusts the overall output from -80 to +6 dB.
