For the Consumer’s Protection: In order to ensure the highest level of customer satisfaction, “new” McIntosh products may only be purchased over-the-counter or delivered and installed by an Authorized McIntosh Dealer. McIntosh products that are purchased over the Internet, by phone or mail order are presumed to be “used” and do not qualify for any McIntosh Warranty.

MR85 AM/FM Tuner

Dual-Tuner Operation As an expansion option, a McIntosh Dealer may add an additional tuner module. This is ideal for multizone systems, because it creates two tuners

that can be used simultaneously.

Weighted Flywheel

For Manual Tuning An optically encoded weighted flywheel for “dialing

in” stations, reminiscent of the smooth-acting flywheel found in classic McIntosh tuners.

Custom Naming All station presets for each tuner may be labeled with a name containing as many as 8 characters. For example, FM preset 1 could be re- named “JAZZ 1” or “WHRW.”

Spatializer Enhancement This circuit can expand the sound field for FM stations

that have poor separation, or it can provide a pseudo-stereo effect for AM stations.

DMOS-FET RF Amplifier This circuit provides very high sensitivity with ultra-low distortion.

Linear Phase, Piezoelectric If Filters Never requiring adjustment,

these filters – together with the associated IF amplifier – provide more than 120dB of gain and selectivity greater than 90dB.
