LineDrive Series

Easily upgrade your factory audio system

The “LineDrive” series of high-performance, OEM preamplifers were specifically designed to provide a premier quality interface between increasingly complex factory audio and navigation systems, which now include an array of convenience features, making it less attractive to replace your “radio” with an aftermarket CD or NAV unit.

Many of these systems now feature multi-channel amplification, some with 2 or even 3-way “active” systems, making the traditional passive, Line Output Converter (“LOC”) products not an option.

However these factory systems lack the traditional RCA low-level signal outputs that high-quality amplifiers need to work. 

So the LineDrive series provide these, making it easy to upgrade your vehicles system, without resorting to excessive DSP based processors, which typically cost several hundred dollars.

These factory power amplifiers often include built-in equalization, to help compensate for vehicle acoustic signatures.  The LineDrive preamps all accept 400 – 500 watts (35 – 45V RMS) per channel on their balanced input sections, and then provide a high-quality RCA output, at high voltage (4 – 9.5 volts), to insure additional aftermarket amplifiers work optimally.

Addressing the unique needs of vehicle acoustics

Audiomobile pioneered the high-voltage preamp concept, in the 80′s with the remarkable SP 300 preamp, which replicated all the features of a high-end home audio preamp, but specifically designed to address the unique acoustic signature of vehicles.

While the need for some of these features is now no longer necessary, as many of these advanced features are included in the factory system, the need for a high-voltage, low-noise preamplifer, to drive aftermarket power amplifers to optimum performace, is still just as relevant as ever.
