REDBACK

 is a registered trademark of Altronic Distributors Pty Ltd

Since 1976 Redback amplifiers have been manufactured in Perth, Western Australia by Altronics. With close to 40 years 
experience in the commercial audio industry, we offer consultants, installers and end users reliable products of high build 
quality with local product support. We believe there is significant added value for customers when purchasing an 
Australian made Redback amplifier or PA product

Australian Made Status

All Redback house products made by Altronics will now be sporting the official Australian Made logo. Since starting manu-
facturing of commercial audio equipment in the mid 70’s we have always taken pride in producing a quality local product.

The new adoption of the Australian Made logo will help us get the word out to local and export markets that our 
products carry the official compliance seal of the Australian Made campaign. We have always pushed our ‘local is better’ 
line in all of our marketing efforts, it’s always an added boost when you are backed up by a widely recognised and
respected icon.

Industry leading 10 year warranty.

There’s a reason we have the industry leading DECADE warranty. It’s because of a long tried and tested history of 
bulletproof reliability. We’ve heard PA contractors tell us they still see the original Redford amplifier still in service in schools 
- that’s over 39  years of operation - and still going strong!
