{"product_id":"audio-research-reference-160m-mkii-mono-amplifier","title":"Audio Research Reference 160M MkII Mono Amplifier","description":"\u003cp\u003eThe Reference 160M MkII monoblock amplifier combines advanced tube technology with refined engineering for exceptional musical performance. Featuring four KT150 output tubes, two 6H30 drivers, switchable Ultralinear\/Triode modes and proprietary auto-bias with tube monitoring, it delivers powerful dynamics, deep bass and outstanding clarity. A redesigned signal path with fewer, higher-grade components and a high-current power supply improves transparency and musicality. The signature GhostMeter™ display doubles as an adjustable power meter, blending style with functionality. Compatible with multiple tube types and requiring no manual bias adjustment, the REF160M MkII sets a new benchmark in performance, design and usability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Output:\u003c\/strong\u003e 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 “condition” i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not critical)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Bandwidth:\u003c\/strong\u003e (-3dB Points) 5Hz to 70kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e (-3dB points at 1 watt) 0.5Hz to 110kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Sensitivity: \u003c\/strong\u003e2.4V RMS Balanced for rated output.
