McIntosh does not warrant, in any way, products that are purchased from anyone who is not an Authorized Dealer or products that have had their serial number altered or defaced. 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.
