Ausstattung & technische Daten
Tecnical Details
POWER OUTPUT 75 watts per channel continuous from20Hz to 20kHz. 1kHz total harmonic distortion typically 0.6% at 75 watts, below 0.05% at 1 watt. Approximate actual power available at ‘clipping’ 76 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) 7Hz to 60kHz.
FREQUENCY RESPONSE (-3dB points at 1 watt) 0.7Hz to 75 kHz.
INPUT SENSITIVITY 1.4V RMS BAL for rated output. (25 dB Bal gain into 8 ohms.)
INPUT IMPEDANCE 300K ohms Balanced.
OUTPUT POLARITY Non-inverting. Balanced input pin 2+ (IEC-268).
OUTPUT TAPS 8 ohms, 4 ohms.
OUTPUT REGULATION Approximately 1.0dB 8 ohm load to open circuit (Damping factor approximately 8).
OVERALL NEGATIVE FEEDBACK 15dB.
SLEW RATE 10 volts/microsecond.
RISE TIME 4.0 microseconds.
HUM & NOISE Less than 0.06mV RMS – 112dB below rated output (IHF weighted, input shorted).
POWER SUPPLY ENERGY STORAGE Approximately 520 joules.
POWER REQUIREMENTS 105-125VAC 60Hz (210-250VAC 50Hz) 410 watts at rated output, 500 watts maximum, 230 watts idle.
TUBES REQUIRED 2 – Matched pair KT150 – Power Output; 2 – 6H30 Driver.
DIMENSIONS 19" (48.3 cm) W x 8.75" (22.2 cm) H x 19.5" (49.5 cm) D. Handles extend 1.5" (3.8 cm) forward.
WEIGHT 47 lbs. (21.3 kg) Net; 63 lbs. (28.6 kg) Shipping.
