Amplifier Power, Amplifier Gain And Limiter Settings; System Configurations - Martin Audio DX2 Software Manual

Note that the DX2 will default to its previous condition if the above operations are
not completed and no buttons are pressed for 20 – 30 seconds.

Amplifier power, amplifier gain and limiter settings

We suggest you specify an amplifier capable of meeting the loudspeaker's peak
power rating – as long as you use the correct Martin Audio limiter
recommendations. The limiter parameters protect the loudspeaker from long-
term overloads whilst the correct amplifier specification protects the loudspeaker
from transient overloads and clipping.
Limiter thresholds are factory preset for power amplifiers with the pro-audio
voltage gain* standard of 32dB (x40).
* We recommend using power amplifier voltage with known gain settings if at all
possible. Manufacturers' sensitivity settings are not very useful as the resulting
gain figures will vary from model to model depending on their power
specifications causing spectral imbalance when using mixed amplifier set-ups.
If you use a power amplifier set to a different gain standard, make absolutely
sure it is set to that gain and adjust the limiter threshold settings as follows:
Power amplifier gain

26dB (Crown standard)

System configurations

Your Martin Audio DX2 Loudspeaker Management System must be correctly
patched.
