1: Description
Application
Thank you for choosing the Martin Audio Engineer for your application. The Martin Audio Engineer is a
powerful, advanced audio DSP product, built into a 19” rack mount enclosure, designed for permanently
installed entertainment audio systems.
On top of the ‘normal’ crossover and routing functionality The Martin Audio Engineer features two unique
highly advanced specialist audio algorithms.
The first one being the dream of every audio reinforcement system installer and owner: an automated sound
engineer-in-a-box called ‘The Engineer’, operating 24-7 to maintain a quality, consistent sound in the venue.
The second one being the Basscreator algorithm, a psycho acoustical effects module which gives the
appearance that small speakers are sounding like they are a lot bigger, with unexpected amounts of perceived
low-frequency output.
The device also features an advanced scheduler, to have presets recalled at pre-programmed time events.
Furthermore, the device features an external remote control panel which can be connected through a RS-485
port.
This RS-485 port can also be used for controlling the device with third party serial control systems.
The combination of these features makes the Martin Audio Engineer an outstanding one-box problem solver
for any installation where high quality and ease of operation are important factors.
