Selecting a specific preset
Each binary file will load a family of presets into your DX1.5.
Please note that the DX1.5 will retain its current preset until instructed to change to
one of the newly loaded ones.
Change the DX1.5's settings to one of the newly loaded presets as
follows:
Press the blue

Note that the DX1.5 will default to its previous condition if the above operations are not
completed and no buttons are pressed for 20 – 30 seconds.
Input parameters
Input parameters are not usually specified within standard Martin Audio presets – hence the
Crossover only selection above.
When configuring a new system always ensure that there are no input gain, base delay or
input eq settings left on the input sections by previous users.

Amplifier power, amplifier gain, DX1.5 primary limiter
and ClipLim settings
Amplifier power
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.
Primary limiters
The primary Limiter parameters protect the loudspeaker from rms heating effects whilst the
correct amplifier power specification and ClipLim settings protect the loudspeaker from
transient overloads and clipping.
Primary Limiter thresholds are factory preset for new products and recommended in the user
guide CD controller spreadsheets for older products. Factory preset primary Limiters are set
for power amplifiers with the pro-audio voltage gain* standard of 32dB (x40). Spreadsheet
recommendations for older products show a range of primary Limiter settings depending on
your chosen amplifier gain/sensitivity.
* 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 have to use a power amplifier set to a different gain standard, make absolutely sure that
you adjust the 32dB standard factory preset or spreadsheet recommendation as follows:
