The MR89 features exclusive McIntosh radio frequency (RF) circuitry that is capable of receiving both strong FM signals from nearby stations – something that can overload and cause distortion in lesser tuners – while also being able to tune in weaker FM signals located further away with little to no noise. The MR89's advanced signal quality monitor can display detailed signal, multipath, and noise levels of the incoming RF signals to help fine tune optimal placement of your AM or FM antenna.

A multitude of advancements have been made in the MR89 to make your radio listening more pleasurable. Sensitivity, Signal to Noise Ratio, Harmonic Distortion, Channel Selectivity, and Stereo Separation were thoroughly analyzed and thoughtfully updated resulting in substantial performance improvements for each. A variety of new features have also been added. To help with lower quality FM stereo broadcasts, Stereo Blending has been upgraded with the introduction of a new High Blend option which blends the high frequency portion of the audio frequency range more aggressively. The new Softmute feature reduces audio output when receiving low quality stations or between-station static and noise. Another added method to reduce noise and enhance your listening experience is the new Highcut function that reduces high frequency audio content. Several aggressiveness settings are available for Stereo Blending, High Blend, Softmute, and Highcut to suit station quality and your listening preferences.
