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 an 8 x 8 routing matrix, the Engineer features the BassCreator
and Engineer algorithms. These unique, innovative functions offer
solutions to some of the most common operational and environmental
problems encountered in audio system design.
