Introduction

Dear Customer,

LTO

Thank you for choosing this ALTO Mobile ADP Series Full-Range Class-D Power Amplifier. We hope you will enjoy using this product as much as we enjoyed developing it. The ADP Series is the result of considerable research and development in our R&D centers in Europe and the Far East. It is a very close cousin of ALTO's professional Class-D amplifier models. We've been designing products for musicians and recording studios for a long time, so the car audio product you now have in your hands has an unusually fine pedigree.

You have purchased a technologically advanced and powerful amplifier. Don't let its size fool you. Its very high efficiency means that, unlike a conventional Class-AB amplifier, it doesn't require a large, heavy heatsink to dissipate heat. Instead, far more of the power going in is sent out in the form of acoustic power to drive your speakers. If your new ADP power amp used conventional circuitry, it would be at least three times the size and four or five times heavier. So you could say it really is a 'little monster' of an amp!

If you have not had your new amplifier installed in your vehicle, that is obviously the first thing you will need to do. We strongly recommend that you have the unit professionally installed by a specialist company authorized by the ALTO Mobile distributor in your country. The installation instructions in this manual are not intended to be a thorough explanation of all the steps involved in correctly fitting this unit. The instructions assume that the person installing the equipment has been trained to carry out such work.

You are an important member of our team. We listen to what our customers say and take on board their suggestions. It is this feedback that helps us create the products you want. So if you have any comments, please let us know via email to "feedback@altomobile.com".
