Measuring and creating presets for loudspeakers.
a) Very expensive and advance measurement
system and logistic (anechoic chamber) is necessary
for make a presets.
b) Factory presets is the basics for any custom
preset design and warranty.
c) …. With a good equipment, growing up
experience and lucky we can make a preset from
the scratch.

…about loudspeaker Power
Electromechanical transducers transform a significant amount
of power into heat.
They can accept different power level according to the time
and dynamic of the signal apply.
long term > 2 h (AES), better know as RMS  CF < 6 dB
Program – Music > 2 h (Recommended amplifier) CF > 6 dB
short term < 2 s (peak / IEC268-5) CF > 12 dB
Eg. Long term power
Program, Music (Recommended amplifier)
Short term power IEC 268-5

Power Limiter Threshold W
• TruePower is the preferred setting to choose when
the number of speakers connected to the amplifier
channel is known.
Powersoft suggest a threshold of 1\3 of the power
specification of the loudspeaker
Eg. 750 W AES = 250 W
• Equivalent power @ 8 Ohm setting all power
calculations being based on an arbitrary 8 ohm load
(RMS voltage limiter), unknow speaker number.
Peak limiter Threshold V
• Powersoft supply a excel file for calculate it
(DesignersTool_1.2.5_a.xlsx) or you can use the
formula
Vlim =
𝑊𝐴𝐸𝑆 ∗ 𝑅 ∗ 1,7
• Eg. 2000 W AES @4 ohm = 152 V
NOTE: For very heavy use (24\7 - CF < 3 dB) I suggest
a 1,4 multiplier
• Eg. 2000 W AES @4 ohm = 125 V
