Audio Research Reference 250 SE

Audio Research Reference 250 SE: (REF 250SE)

Puissance de sortie: 280 watts par canal continu de 20Hz à 20kHz. 1kHz total harmonic distortion typically 0.5% at 280 watts, below .04% at 1 watt. Approximate actual power available at clipping 270 watts (1kHz). (Note that actual power output is dependent upon both line voltage and condition i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
Bande Passante: (-3dB points) 5Hz to 70kHz
Réponse en Fréquence: (-3dB points at 1 watt) 0.5Hz to 110 kHz.
Sensibilité d’entrée: 2.4V RMS Balanced for rated output. (25.5 dB gain into 8 ohms.)
Impédance d’entrée: 200K ohms XLR.
Borniers de sortie: 4, 8, 16 ohms.
Régulation de sortie: Approximativement 0.9dB 16 ohm en circuit ouvert (Damping factor approximately 10).
OVERALL NEGATIVE FEEDBACK: 8.8dB.
Taux de balayage: 20 volts/microsecond.
Temps de montée: 1.5 microseconds.
Rapport Signal Bruit: moins de 0.2mV RMS – 110dB below rated output (IHF-A weighted, input shorted, 16 ohm output).
Energie de stockage de l’alimentation: Approximativement 900 joules.
Alimentation Eléctrique: 260 250VAC 50Hz – 770 watts à puissance nominale, 1000 watts maximum, 380 watts en veille, 1 watt off.
