The equipment should be situated so that its location or position does not interfere with its proper
ventilation. For example, the product should not be situated under carpeting or in a totally sealed
enclosure. Trunk-mounted equipment/amp racks should be well ventilated, using forced air cooling fans if
necessary. The equipment should be situated away from heat sources such as engine exhaust systems and
radiators.

Preface
Dear Customer,
Thank you for choosing the ALTO Mobile DRIVE20 2-way digital crossover/speaker management system.
We hope you'll love the results you get from your new digital sound processor and enjoy using it as much as
we enjoyed developing it.
The DRIVE20 is the result of considerable development work in our R&D centres in Europe and the Far East
and is a close cousin of ALTO's professional audio products. We've been designing products for musicians
and recording studios for many years - the product you now have in your hands has a fine pedigree.
The core of our digital audio products is a sophisticated DSP (Digital Signal Processor) coupled with state-of-
the-art algorithms developed by our software team over the last 7 years.
The car audio environment is worlds away from the controlled listening area of the recording studio, and yet
much of the sound processing so important to recording engineers can be applied with spectacular success
to the automotive environment. ALTO Mobile is a specialist division of audio and computer software
engineers, but above all we're car audio enthusiasts. We love the challenge of trying to reproduce studio
quality sound inside a moving vehicle.
