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 PowerElectromechanical 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 dBProgram – Music > 2 h (Recommended amplifier) CF > 6 dBshort term < 2 s (peak / IEC268-5) CF > 12 dB

Eg. Long term power 500 W AES Program, Music (Recommended amplifier) 1000 W RMS Short term power IEC 268-5 2000 W PEAK

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 loudspeakerEg. 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

• Eg. 2000 W AES @4 ohm = 152 VNOTE: For very heavy use (24\7 - CF < 3 dB) I suggest a 1,4 multiplier• Eg. 2000 W AES @4 ohm = 125 V
