Overview
Simply put, the REF150 is a breakthrough in stereo power amplification. Replacing the REF110—which was one of the most respected modern stereo amplifiers—was a daunting task, but it has been accomplished. The REF150 offers more power, greater dynamic thrust, a more vivid and resolved presentation, greater finesse, and quieter operation. It is the new benchmark.
Specification
SPECIFICATIONS
POWER OUTPUT: 150 watts per channel continuous from20Hz to 20kHz. 1kHz total harmonic distortion typically 0.6% at 150 watts, below 0.03% at 1 watt. Approximate actual power available at ‘clipping’ 160 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) 5Hz to 80kHz.
FREQUENCY RESPONSE: (-3dB points at 1 watt) 0.5Hz to 120 kHz.
INPUT SENSITIVITY: 2.0V RMS BAL for rated output. (24 dB Bal gain into 8 ohms.)
INPUT IMPEDANCE: 300K ohms Balanced.
OUTPUT POLARITY: Non-inverting. Balanced input pin 2+ (IEC-268).
OUTPUT TAPS: 16 ohms, 8 ohms, 4 ohms.
OUTPUT REGULATION: Approximately 0.6dB 16 ohm load to open circuit (Damping factor approximately 14). OVERALL NEGATIVE FEEDBACK: 14dB.
SLEW RATE: 13 volts/microsecond.
RISE TIME: 2.0 microseconds.
HUM & NOISE: Less than 0.1mV RMS – 114dB below rated output (IHF weighted, input shorted).
POWER SUPPLY ENERGY STORAGE: Approximately 1040 joules.
POWER REQUIREMENTS: 105-125VAC 60Hz (210-250VAC 50Hz) 730 watts at rated output, 900 watts
maximum, 420 watts idle.
TUBES REQUIRED: 4 – Matched pair KT120 – Power Output; 4 – 6H30 Driver.
