McIntosh MR85 Tuner

Vinyl Renaissance Not Just Another Record Store!

The MR85 features a new "smooth-dialing" flywheel system for manual tuning, permanent memory for all settings and selectable auto-mute for local/distance tuning. An alphanumeric fluorescent display indicates station frequency, station preset, signal strength and band. All nine AM and nine FM presets for each tuner can be custom labeled with any desired name up to eight characters. The MR85 ships with one TM1.

The MR85 is a very high-performance AM/FM broadcast monitor. When you add a second TM1 Tuner Module two people can enjoy superior off air broadcast reception simultaneously.

MR85 AM/FM Tuner Features

Dual-Tuner Operation

As an expansion option, a McIntosh Dealer may add an additional tuner module. This is ideal for multi-zone 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 renamed “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.
