The new MEN220 Room Correction System by McIntosh delivers a potent suite of Room
Correction, Custom-EQ and 2-Way Crossover capabilities in one easy-to-use stereo
component. While any single feature of the MEN220 has the power to optimize the sonic
characteristics of the highest quality audio systems, combining the features can reveal a
level clarity and resolution unattainable by any other means. Styled in the rich tradition of
McIntosh audio components the MEN220 features our trademark Fiber-Optic Illuminated
Black Glass Front panel and aluminum casework. Front panel buttons and control knobs
bring a familiar, easy-to-use analog interface to this digital product just as a 2-line
vacuum fluorescent display reports status and aids in set-up of the MEN220. Full system
control and PC link are provided via RS232 while McIntosh Data, Power Control and
IR inputs offer additional remote control flexibility. Both single-ended and balanced
connections are supported; a hand-held, IR remote control is included.

ROOM CORRECTION
The effect of room acoustics on the quality of music playback is well known to music
aficionados, and it is not uncommon to see peaks and dips between +10 to –20 dB in
the frequency response. The mechanism by which this occurs is as complex as the
range of listening rooms and audio components are variable; no two situations are alike.
The MEN220 harnesses the power of RoomPerfectTM* software, an advanced room
correction algorithm that automatically creates a digital model of your listening room,
called RoomKnowledge. By using data gathered from multiple locations in the room, the
MEN220 corrects frequency response anomalies – revealing, perhaps for the first time,
the full capabilities of your fine audio system.
EQ
A 6-Band Parametric EQ Application (that runs on any Windows PC) allows the creation of
specialized Voicing Curves to suit the tastes of the user, or to solve specific issues such as
refreshing inferior but still-cherished source material, or compensating for inferior formats.

“SMART” CROSSOVER
MEN220 contains a sophisticated, phase coherent 2-way electronic crossover that allows
for true loudspeaker bi-amping or seamless integration of mono or stereo subwoofers.
