核心的组件“真空管”而言，全都先经过连续48小时工作的试炼，接着才量测其特性数据，并依据电路的特性使用特定数值配对的真空管，保证左右声道的一致性能。Reference 150由于没有采用传统的胆管外露的开放式设计，而是采用了箱式半封闭设计，所以需要辅助散热，配备有两把低噪音大口径风扇，协助机器散热。Audio Research Reference 150整体体积为48,3 x 22,2 x 49,5 cm (HxBxD)，重量41 kg，功耗420w-900w。

 

详细参数：

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.
DIMENSIONS: 19"(48.3cm)Wx83⁄4”(22.2cm)Hx191⁄2”(49.5cm)D.Handlesextend11⁄2”(3.8cm)forward.
WEIGHT: 75lbs.(34.2kg)Net;90lbs.(41kg)Shipping.
