The Martin Audio Engineer is an advanced, powerful digital signal
processor designed to provide comprehensive control and
management of installed loudspeaker systems.

Incorporating a broad range of standard facilities; gain, EQ, limiting,
time delay and a 4 x 8 routing matrix, the Engineer features the
BassCreator and Engineer algorithms. These unique, innovative
functions offer solutions to some of the most commonly encountered
operational and environmental problems encountered in audio system
design.
