Classic McIntosh Design: The MR87 AM/FM tuner incorporates classic
McIntosh design cues, including a black glass front-panel, rotary knobs,
illuminated logo, stainless steel chassis, & gold-plated connectors. The MR87's
smooth acting weighted tuning mechanism with glass dial and illuminated pointer
resembles that of the classic McIntosh analog tuners from the 60's and 70's.
AM/FM Tuner: The McIntosh MR87 tuner excels at receiving traditional
AM and FM broadcasts. It features proprietary radio-frequency (RF) circuitry to
receive strong FM signals from nearby stations without distortion, while
also receiving weaker FM signals located further away with little to no noise.
The included RAA2 AM antenna features a 20' long cable that allows flexibility
in placing the antenna in order to achieve the best AM reception (no FM antennas
is included). The MR87's advanced signal quality monitor can display the
multipath and noise levels of the incoming RF signal to help fine tune antenna
placement for optimal reception.
Tuning Methods: The McIntosh MR87 offers Manual, Seek,
Preset, and Direct AM/FM station tuning. You can store up to 40 total station
presets - 20 FM and 20 AM.
Stereo/Mono Mode: The MR87 tuner automatically switches between Stereo
and Monaural FM Broadcasts. You can manually activate the tuner's Mono mode for weaker FM stations to
combine left and right stereo signals to a monophonic audio signal.
RDS Text Info: The MR87 tuner supports the display of RDS (Radio Data
text from many FM radio stations, programs, & channels. When
available from a FM broadcast station, the text information appears on the
second line of the tuner's front-panel display. It may also scroll from
right to left, this is for information not possible to display at the same time.
This information may include some or all of the following -
- Station Call Letters and/or Frequency
- Type of Program and/or music format
- Name of the Artist
- Name of the Song
Balanced & Unbalanced Analog Outputs: The MR87 is fitted
with both balanced & unbalanced analog outputs to connect the AM/FM tuner to
your home audio system. There is a balanced stereo XLR output and an unbalanced
stereo RCA output. Balanced connections guard against induced noise and allow
long cable runs without compromising sound quality. The balanced
and unbalanced outputs may be used simultaneously.
Optical & Coaxial Digital Outputs: The McIntosh MR87 is also equipped
with an optical (toslink) digital output and a coax (RCA) digital output for
connection of the AM/FM tuner to your home audio system.
Front-Panel & Remote Control: The MR87 AM/FM
tuner offers front-panel controls, including Preset & Tune rotary knobs, and the
following push-button controls - Standby/On, Band, Seek Up/Down, Mono/Stereo,
Store/Exit, Display, & Category. The included IR remote provides full wireless
operation of tuner. The remote can also be used to operate other McIntosh
Fluorescent Display: The two line multifunction fluorescent display indicates artist
name, station call sign, music genre, and song title; as well as setup
functions. The brightness level of the fluorescent display can be adjusted from
Linear Power Supply: The MR87 utilizes a linear power supply with a custom-wound R-Core transformer
and nested regulation to insure optimum performance of all circuits.
Custom Integration: The McIntosh MR87 offers advanced
connectivity and control features often required for custom home integration.
- IR Input: The 3.5mm IR input allows the connection of
an external IR receiver. With an external sensor connected to the MR87,
remote control operation of the system is possible from another room and/or
when the MR87 is located in a cabinet with the doors closed. The signal from
a connected external IR receiver will have priority over the signal from the
tuner's front-panel IR sensor.
- Power Control: The MR87 has the ability to
automatically switch power on or off to and from source components via the
Power Control In/Out connections (3.5mm).
- Data Port: The MR87's Data Out Port (3.5mm) sends
remote control signals to a McIntosh source component. This Data Port
connection allows for the remote operation of basic functions using the
MR87's remote control.
- RS-232C Port: The tuner's RS-232C port requires a 3.5mm
stereo minijack to a subminiature DB 9 connector cable (sold separately) to
transmit and receive RS-232 commands.
Mounting Options: The McIntosh MR87 can be placed upright on
a table or shelf, standing on its four feet. It also can be custom installed in
a piece of furniture or cabinet of your choice. The four feet may be removed
from the bottom of the MR87 when it is custom installed. Always provide adequate
ventilation for your MR87. Allow at least 2" above the top, 2" below the bottom,
and 2" on each side of the tuner, so that airflow is not obstructed.
