Now you can take advantage of traditional McIntosh
standards of excellence in the MXA60 Integrated
Audio System.
The Power Amplifier section of the MXA60, with
a power output of 75 watts per channel, will drive
the McIntosh Loudspeakers to a high level of perfor-
mance.
The flexible Preamplifier section provides connec-
tions for external input sources and may also be used
to drive an external Power Amplifier.
The MXA60 AM/FM/STEREO Tuner Circuitry
uses the latest in technology for the best sound quality
with superb station reception.
Audio SACD and CDs are reproduced with flaw-
less realism and the advanced mechanical design of
the transport ensures many years of smooth trouble
free operation.
McIntosh Acoustic Engineers have achieved in the
design of the MXA60 Loudspeaker System a level
of high performance. The MXA60 provides superior
spaciousness sound reproduction with unusual sound
stage depth in a full range system.
The MXA60 reproduction is sonically transparent
and absolutely accurate. The McIntosh Sound is “The
Sound of the Music Itself.”
Introduction Performance Features
• Power Output
The MXA60 consists of a 75 watts per channel stereo
Power Amplifier with less than 0.05% distortion. The
Power Amplifier uses Thermal Trak
1
Output Tran-
sistors for lower distortion and cool operation. The
amplifier bias is precisely controlled over a wide range
of music conditions
• Power Guard
The patented McIntosh Power Guard circuit prevents
amplifier clipping and protects the McIntosh Loud-
speakers.
• Illuminated Power Meters
The large Illuminated Power Output Watt Meters on
the MXA60 respond to 95% of a full scale reading to
a single cycle tone burst at 2,000 Hz signal. When the
pointer reaches its peak it pauses long enough for the
human eye to perceive its position, then decays.
• Electronic Switching
The Preamplifier uses Electronic and Electromagnetic
Switches for reliable, noiseless switching.
• Vacuum Tube Preamplifier
The preamplifier section includes vacuum tube ampli-
fication. The vacuum tube is illuminated amber dur-
ing the warmup period and green during operation.
• Balanced and Unbalanced Inputs
The Balanced Input allows the connection of a source
component using long cable lengths without a loss in

sound quality. The Unbalanced input has high sensi-
tivity for compatibility with battery powered personal
players.
• External Input Level Match and Renaming
The MXA60 External Inputs may be renamed and the
volume levels are adjustable to match the volume level
of the built-in Tuner and SACD/CD Player.
• Precision Tracking Volume Control
Volume levels are controlled by a Digitally Controlled
Attenuator System with a tracking accuracy of 0.1dB.
• Variable Rate Volume and Balance Control Selec -
tion
The Preamplifier’s Volume and Balance Control
Circuitry provides an ideal rate of change with control
rotation.
• Electronic Tone Controls with Auto Bass
Electronic Bass and Treble Circuitry allows volume
level adjustments for low and high frequencies in
precise one Decibel Steps. The Auto Bass circuit
automatically increases the volume of low frequencies
when listening at low volume levels.
• Information Service
The MXA60 will indicate various text information
such as Station Call Sign, Music Genre, Artist Name
and Song Title when transmitted by the Radio Station.
• Special FM RF Tuned Circuitry
The MXA60 RF Circuitry receives strong local FM
Station Signals without distortion and receives even
the weakest of FM Signals with low noise.
