RESEARCH REF 75 SE
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.
Tube Complement: 2 – Matched pair KT120 – Power Output; 2 – 6H30 Driver.
Dimensions: Width 19" (48.3 cm)
Height 8.75" (22.2 cm)
Depth 19.5" (49.5 cm)
Handles extend 1.5" (3.8 cm) forward.
Weight: 47 lbs. (21.3 kg) Net; 63 lbs. (28.6 kg) Shipping.
