10 YEAR EXTENDED WARRANTY SCHEME

The product price includes 5 years' warranty and 30 day money back guarantee.

However, the AV.com 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 10 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 180 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first 2 years in the event of an item becoming faulty
  • Claim 50% cash back on the cost of the policy after 10 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 UK, 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 AV.com and manufacturer warranty policies, and the AV.com 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.

JENO Engine

The Technics JENO Engine (Jitter Elimination and Noise-shaping Optimization) is a proprietary technology developed by Technics to provide high-quality sound reproduction. The JENO Engine moderates jitter and optimizes the noise-shaping process to deliver a clear and focused sound. This technology is featured in some of Technics' most advanced audio systems and is instrumental in establishing a more realistic listening experience.

Load Adaptive Phase Calibration

The question of matching an amp to speakers can keep you up at night. Every system is unique. That’s why Technics have integrated LAPC (Load Adaptive Phase Calibration). It works by analysing the characteristics of connected speakers and compensating gain and phase characteristics for each frequency band. This ensures sound waves from each speaker arrive at the listener's ears simultaneously, resulting in more natural sound reproduction.

Twin Power Supply

This unit is equipped with a twin power supply for both digital and analogue circuits. Fundamentally isolated from one another, the high-speed switching power supply circuit uses damping materials to absorb vibrations and reduce noise. As a result, the power supply operates practically silently, allowing for clear and precise audio output. This is a sophisticated quasi-resonant power supply upgraded directly from the premium SA-C600 network receiver.

Expansive Streaming

With Chromecast, AirPlay 2, Spotify, TIDAL, Qobuz, Deezer, Amazon HD, and DAB/DAB+/FM and internet radio compatibility, as well as easy Bluetooth connectivity, this is so much more than a regular network amplifier. Whether entertaining guests or spending an evening alone, this is the perfect addition to any modern home.

Flexible Physical Connectivity

Easily connect a TV or other HDMI devices to enjoy high-quality sound with the available HDMI ARC input. The USB A / B connections also offer lossless playback potential, while the line and digital inputs round out the plethora of choices to connect to. Plus, with a headphone connection, you can enjoy your music in peace.

Low-noise MM Phono

The Technics Grand Class grade low-noise Phono MM input is a premium audio input that is designed to minimize noise and distortion whilst giving you a direct connection to your turntable. Technics use high-quality components to ensure precise sound reproduction, an excellent choice for the discerning audiophile.

Key Features

  • Experience audiophile-grade sound with JENO Engine & LAPC technology
  • Powerful, silent-running digital & analogue circuits for low noise and interference
  • Connect wirelessly to Chromecast, AirPlay2, Wi-fi, Bluetooth & more
