8.4
Engineer
Installed system digital management processor
The Martin Audio Engineer 4in/8out and 8in/8out digital management processors provide comprehensive
control and management of installed loudspeaker systems.
In addition to crossover, EQ and limiter functions, Engineer processors offer a flexible event scheduler,
automatic programme level and tonality control to compensate for variations in programme sources and a
unique psycho-acoustical BassCreator algorithm.
BassCreator is capable of extending the perceived range of small loudspeakers 1 to 1½ octaves below the
resonance frequency of a loudspeaker without overloading the loudspeaker and without creating sub-sonic
sound leakage.
Engineer processors are supplied pre-loaded with a limited range of Martin Audio presets. Bl
presets will be made available shortly from
www.martin-audio.com
for loading via a pc.
A note on the illustrations
Please note that for simplicity only the left channel is shown and each line in the diagram represents a pair
of wires.
The illustrations show systems configured using the cost-effective Martin Audio M3
+
controller. Larger,
zoned systems may require the more comprehensive facilities offered by Martin Audio digital controllers like
the DX1, DX2 or Engineer. See above for details.
The M3
+
controller’s internal crossover card must be properly configured for the system to be used. Please
see the
M3
+
configuration notes
later in this user guide for further information.
