Standard di misura HERTZ
Potenze misurate secondo lo standard HERTZ edizione 2007
- 12 VDC e 14.4 VDC;
- 1 kHz o frequenza di taglio del crossover;
- 0.3% THD @ potenza nominale; 1% THD @ potenza continua;
- Tolleranza: +10%, - 5%;
- Potenza continua misurata applicando una tensione RMS su carico resistivo;
- Potenza nominale misurata utilizzando una batteria da 12 VDC con un carico di 4 Ohm e tutti
i canali in funzione.
HERTZ measurement standard
Power measures taken according to HERTZ standard, 2007 edition
- 12 VDC and 14.4 VDC;
- 1 kHz or crossover cut-off frequency;
- 0.3% THD @ nominal power; 1% THD @ continuous power;
- Tolerance: +10%, -5%;
- Continuous power given by RMS Voltage measured on resistive load;
- The nominal power of the amplifier is measured upon a battery Voltage of 12 VDC
with a 4 Ohm load and with all channels in function.
