After two years of development, the all-new Reference 160M MkII (REF 160M MkII) monaural power amplifier is unique in its construction, appearance, and sound quality\u2014an amplifier you’ve never heard before, yet it is undoubtedly a classic from Audio Research. It employs a sophisticated audio topology with fewer components in the signal path than ever before, yet delivers superior performance. It supports ultra-linear\/transistor switching, boasts proprietary automatic biasing, output tube monitoring and protection, an advanced power meter, and more. These features are unprecedented in Audio Research amplifiers.<\/p>\n
Technical Specifications<\/p>\n
POWER OUTPUT- 140 watts continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 140 watts, below 0.04% at 1 watt. (Note that actual power output is dependent upon both line voltage and \u201ccondition\u201d i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not critical).<\/p>\n
POWER BANDWIDTH- (-3dB Points) 5Hz to 70kHz.<\/p>\n
FREQUENCY RESPONSE- (-3dB points at 1 watt) 0.5Hz to 110kHz.<\/p>\n
INPUT SENSITIVITY- 2.4V RMS Balanced for rated output. (25.5 dB gain into 8 ohms).<\/p>\n
INPUT IMPEDANCE- 200 k ohms Balanced.<\/p>\n
OUTPUT POLARITY- Non-inverting. Balanced input pin 2+ (IEC-268).<\/p>\n
OUTPUT TAPS- 16 ohms, 8 ohms, 4 ohms.<\/p>\n
OUTPUT REGULATION- Approximately 0.6dB 16 OHM LOAD TO OPEN CIRCUIT (Damping factor approximately 14).<\/p>\n
OVERALL NEGATIVE FEEDBACK- 14dB SLEW RATE: 13 volts\/microsecond RISE TIME: 2.0 microseconds.<\/p>\n
Physical Specifications<\/p>\n
POWER REQUIREMENTS- 105-130VAC 60Hz (210-250VAC 50Hz) 400 watts at rated output, 700 watts maximum, 260 watts at \u201cidle\u201d, 1 watt off.<\/p>\n
TUBES REQUIRED- 2 matched pair KT150 (Power output V1-4); 2 6H30 (Gain stage V5 and V6).<\/p>\n
