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 “condition” i.e.:

if power line has high distortion, maximum power will be aected adversely,

although from a listening standpoint this is not critical). Power Bandwidth:

(-3dB Points) 5Hz to 70kHz. Frequency Response: (-3dB points at 1 watt)

0.5Hz to 110kHz. Input Sensitivity: 2.4V RMS Balanced for rated output.

(25.5 dB gain into 8 ohms). Input Impedance: 300k ohms Balanced; 100k

ohms Single-ended. Output Polarity: Non-inverting. Balanced input pin

2+ (IEC-268). Output Taps: 16 ohms, 8 ohms, 4 ohms. Output Regu-

lation: 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. Power Requirements:

105-130VAC 60Hz (210-250VAC 50Hz) 400 watts at rated output, 700 watts

maximum, 260 watts at “idle”, 1 watt o. Tube Complement: 2 matched

pair KT150 (Power output V1-4); 2 6H30 (Gain stage V5 and V6). Dimen-

sions: Width 19.0” (48.26 cm), Height 10.25” (26 cm), Depth 18.5” (46.4 cm).

With Handles and Connectors: 20.75” (52.7 cm). Weight: 56lbs (25.5 kg) Net,

73lbs (33.2 kg) Shipping.

After two years in development, the new Reference 160M Monaural

Power Ampliﬁer is built like no other, looks like no other, and sounds like

no other ampliﬁer that you have ever heard, but it is unmistakably Audio

Research. It features a reﬁned audio topology with fewer and better

components in the signal-path than in previous designs, switchable

Ultralinear/Triode operation, proprietary auto bias, output tube monitoring

and protection, an advanced power meter, and much more. This array of

features has never been oered before in an Audio Research ampliﬁer.

The designers at Audio Research wanted to create a new style that

would complement the look of the REF6 preamp while also featuring

a transparent faceplate that allows a view of the glowing KT150

vacuum tubes. While the GhostMeter™ allows you to see the output

tubes, it also incorporates an innovative dual-layer construction

with distinctively etched markings that create an integrated power

meter. The power meter’s output-level markings illuminate via

hidden LEDs, and the illumination brightness is adjustable.
