A1.5 DX1 Loudspeaker Management System
Martin Audio can provide factory set configuration cards for a variety of off-the-shelf
crossover systems (contact your dealer or Martin Audio Ltd for further information)
but the Martin Audio DX1 Loudspeaker Management System is strongly
recommended for all new Wavefront system designs.
The Martin Audio DX1 is a very high performance DSP-based controller and
provides crossover, protection, delay and alignment functions. As a Martin Audio
product, the DX1 is kept up-to-date with preset crossover and limiter functions
suitable for a wide range of system configurations and power amplifiers.
DX1 Factory Preset Examples
W8 Rear panel Active/Passive switch
Please note that the W8 rear connector panel is equipped with an Active/Passive
switch.
Active mode (DX1 factory presets 21, 23, 24 or 25)
In Active mode each driver (low-mid, high-mid & high) is driven by its own power
amplifier channel. These power amplifier channels are sourced from the appropriate
DX1 output to ensure optimal crossover and limiter alignment.
The advantages of active mode are:
Ø
Smoother high-mid/high amplitude and phase response
Ø
Smoother high-mid/high vertical polar response
Ø
Improved high-mid/high amplifier headroom
Ø
Improved high-mid/high limiter action
