Comprehensive but never confusing, the Zone 4 will quickly become the core of your audio system. 

The state-of-the-art Zone series from Optimal Audio was created with one core goal in mind - unparalleled control and flexibility in a user-friendly package that is accessible even for those with little experience of managing audio systems. All at a surprisingly affordable price!

The Zone 4 offers groundbreaking audio signal routing and processing and is designed as a pre-amp unit to be connected to your existing power amp. Easily combine audio sources (such as streaming services, phones/tablets, radio, computers, TVs, etc) to create separate mixes in up to four separate zones. And with a large, clear and fully labellable interface on the front of the unit and modern LED dials, you'll never need to second-guess a setting or zone again.

Optimal Audio Webapp

The Optimal Audio WebApp brings the technology behind the Zone series to the end user.

Traditionally, the control and operation of commercial sound systems has been a complicated inconvenience to many users, who just want the system to work. WebApp and ZonePad coupled with the Zone series puts effortless and intuitive control into their hands.

The WebApp has been carefully designed to bring the essential functions and daily operation of your sound system to your smartphone, tablet or laptop. With slick touchscreen-optimised controls, WebApp is designed for ease of use on any device.

The responsive and intuitive interface lays out the fundamental controls in a clean, accessible format with the deeper, lockable layers for system configuration available for integrators and system commissioners.

Zone specific and global presets for manual and time of day triggers.

Complete system configuration can be achieved through the WebApp with ducking, EQs, limiters, advanced signal routing and more.

WebApp also allows for the system configuration files within Zone series products to be saved and easily replicated across multi-site installations.

Hosted by the Zone series, there’s no installation required – just open a browser on a smartphone, tablet or laptop connected to the same network, enter the address and you’re in.

60 Day Returns Policy

We ask that you follow these guidelines to help us process your return as quickly and efficiently as possible:

  1. Please keep your order reference to hand. This confirms your original order and gives us the necessary details to authorise the product's return.
  2. Contact our Customer Services Team on 02476 369890 (or email info@audiovolt.co.uk). We will then send you an RMA number and a returns form, which needs to be completed and sent back with the returned item(s).

Returned items must be mailed within 10 days of when the RMA number has been issued. Items received with a post date 30 days after your requested return will NOT be eligible for refund.

Please note: our returns policy is quite straightforward, but there are a number of conditions that we ask our customers to comply with before applying:

  1. It is your responsibility to request a return. If you don't tell us you want to make a return, we don't know. Once you do tell us, we will do everything we can to action it.
  2. If you have not requested a return within 60 days of receiving an order, we will assume that you are intending to keep it, and we will not authorise a return.
  3. We always refund the payment according to how the original purchase was made and aim to do so within 72 hours of the return being received by us.
  4. Returned goods are liable for a restocking fee of 15% towards handling and repackaging if the order is not returned in its original, unopened packaging. This charge will be subject to our inspection of the returned goods.
  5. Delivery charges will not be refunded unless the delivered goods are faulty.
  6. Replacement products are dispatched immediately after the returned goods have been received and accepted by Audio Volt.
  7. Items that develop a fault within 30 days of delivery are eligible for a replacement or a refund. Delivery costs are also reimbursed for faulty items. Please contact our Customer Services Team on 02476 369890 if you believe your item has developed a fault.
