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.

Each channel's high-pass filter has a variable cut-off frequency of 16 to 420 Hz selected from the front panel and has an attenuation of 18 dB/Octave - also used in the ISA110 module that was introduced during the 80's. The high pass filter, phase-invert, insert point and phantom power can all be switched in and out per channel with the front panel controls.

Eight-segment LED arrays offer clear metering of both signals, whilst a calibration knob on the rear panel enables lining up of analogue signal levels to stop clipping and optimize your signal path for any DAW or recording system.

Superb sound spanning four different decades

Focusrite's microphone preamplifiers go back to the original Focusrite ISA 110 modules, when Rupert Neve was given authority by George Martin in 1985 to build a channel strip for his Neve console. Focusrite mic pres combine the very best solid-state electronics with transformer coupling and have played a key part in the recording of hundreds of hit records, making them the choice of leading artists, producers and engineers around the world.

Lundahl Transformers

ISA products have relied on Lundahl from the beginning, since their components were originally specified in 1985. The LL1538 has a 3-section winding, giving very low leakage inductance and an extended frequency response as a result of this. The Lundahl Transformers are housed in mu-metal cans to protect them from stray magnetism.

Variable input impedance and up to 80 dB of gain

ISA Two has two classic Focusrite mic preamps, with four impedance settings including the original ISA 110 setting. Variable input impedance lets you to go for an accurate, transparent sound or choose to highlight the character of your favourite vintage mic ? and anywhere in between. With up to 80 dB of low-noise gain, ISA Two can perform in even the most demanding situations.

Insert your choice of processors

A fully balanced insert point found via TRS sockets on the rear panel for each channel and is enabled with a front-panel button, making it easy to use outboard processors by plugging in your choice of EQ, compressor or limiter.
