1. Chapter 1: Description
1.1 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 make the Martin Audio Engineer an outstanding one-box problem solver for
any installation where high quality and ease of operation are important factors.
1.2 Features
- 4 inputs and 8 outputs with complete freely routable signal path (Engineer 418)
- 8 inputs and 8 outputs with complete freely routable signal path (Engineer 818)
- 8-band fully parametric EQ on every input.
- 8-band fully parametric EQ on every output.
- Highpass and Lowpass filters on every output with slopes up to 24 dB/oct. featuring L-R, Butterworth
and Bessel filters.
- Speaker alignment delays of up to 10ms on every output.

ENGINEERHARDWAREMANUAL1.1[1].doc 7
- The most musical-sounding speaker protection limiters in the business on every output.
- Very high, musical sound quality throughout.
- Unique Engineer DSP algorithm, working 24-7 to keep a consistent sound in your venue.
- Unique Basscreator algorithm, gives small speakers the perceived low frequency response of a large
speaker.
- Flexible build-in scheduler for automated preset recalling.
- RS-232 interface for extensive PC-based setup and control.
- Windows® PC software for controlling and programming.
- Programmable remote control with RS-485 interface on industry-standard RJ-45 connector.
- Up to 4 remote controls can co-operate on one Engineer through the use of an optional Remote Spider.
