While there is no doubting the popularity and permanence of paid music streaming services, there is still plenty of free music being broadcast over the air from thousands of traditional radio stations. And McIntosh has a long and distinguished history with radio and tuners. The McIntosh MR78 from the 1970s is considered by many to be one of the best – if not the best – tuners ever made. The MR89 AM/FM Tuner carries on with this tradition of tuner excellence by letting you enjoy the abundance of free music streaming over invisible airwaves.

Features

AM and FM radio stations are tuned using the smooth acting tuning knob. The MR89 supports the FM Radio Broadcast Data System (RBDS)1, allowing the display to show various information such as station name, music genre, artist name, and song title (provided such data is transmitted by the station). The RBDS data display can be adjusted or turned off entirely according to your liking. A Seek function is available through either the front panel controls or from the included remote control. The sensitivity of the Seek function is adjustable through setup menus. The MR89 can store up to 20 preset stations in both the AM and FM band.

A pair of 60dB output meters show the signal level that's being delivered from the analog outputs of each channel. While the volume is controlled by your , , or other control device, the meters on the MR89 accurately portray the Left and Right channel audio output generated from the received station. Depending on the program received, the meters are a good indication of the MR89’s excellent stereo separation.

The MR89 can receive the following FM frequencies that are used in the listed regions as well as in many other parts of the world: 87.5MHz – 108.0MHz (Europe); 88.1MHz – 107.9MHz (USA); and 76.0MHz – 108.0MHz (Japan). For AM reception, it can receive 531kHz – 1701kHz (Europe); 530kHz – 1700kHz (USA); and 531kHz – 1629kHz (Japan).
