REFERENCE 750 * Válvulas. Monofónica de 750 W. KT120. La referencia. Entrada XLR. MD. Par

POWER OUTPUT:
750 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at 750 watts, below .04% at 1 watt.
Approximate actual power available at “clipping” 850 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.)

POWER BANDWIDTH:
(-3dB points) 15Hz to 150kHz.

FREQUENCY RESPONSE:
(-3dB points at 1 watt) 1 Hz to 200 kHz.

INPUT SENSITIVITY:
4.6V RMS Balanced for rated output. (24 dB gain into 8 ohms.)

INPUT IMPEDANCE: 200K ohms balanced.

OUTPUT: 4, 8, 16 ohms.

OUTPUT REGULATION:
Approximately 0.5dB 16 ohm load to open circuit (Damping factor approximately 17).

OVERALL NEGATIVE FEEDBACK: 13dB.

SLEW RATE: 20 volts/microsecond.

RISE TIME: 1.5 microseconds.

HUM & NOISE: Less than 0.2mV RMS – 110dB below rated output (IHF-A weighted, input shorted, 16 ohm output).

POWER SUPPLY ENERGY STORAGE:
Approximately 1300 joules.

POWER REQUIREMENTS:
105-130VAC 60Hz (260-750VAC 50Hz) 2100 watts at rated output, 2400 watts maximum, 800 watts at “idle”.

TUBES REQUIRED:
8 Matched pair KT120 Power Output; 1 6550WE Regulator; 1 6H30 Regulator Amplifier; 1 matched pair KT120 Driver; 1 6H30 follower.

DIMENSIONS:
13.5" (34.3 cm) W x 23" (58.4 cm) H x 20.8" (52.8 cm) D. Handles extend 1.5" (3.8 cm) forward and rearward.

WEIGHT:
170 lbs. (77.2 kg) Net; 395 lbs. (180 kg) per pair shipped weight.
