Introduction
The Mclntosh MAC 4100 is a high quality, high
power AM/FM Stereo Receiver. Its design has been
governed by insistence on great flexibility, sensitivi-
ty, high performance with long life. It is easy to use.
Some of the many new improvements designed
for your listening enjoyment Include:
Low noise field effect transistor analog input swit-
ching that keeps signal leads short to reduce possi-
ble noise and hum pickup. Mechanical contact noise
is also eliminated.
LED Input indicators show which source has been
selected and help make input selection faster,
easier, surer and more convenient.
New low impedance transistor technology
reduces hum and noise interference in the phono
preamplifier.
Electronically controlled trimming of the preci-
sion stepped volume control maintains a channel to
channel accuracy of 1 dB. This high order of exact-
ness assures continuing program balance as the
listening loudness is changed.
The five band program equalizer permits the ad-
justment and improvement of the tone contrast of
the five most important listening ranges. Each can
be emphasized or de-emphasized to satisfy your
taste or listening atmosphere without affecting any
of the other ranges.
The high quality power performance is con-
tinuously assured by POWER GUARD. The POWER
GUARD circuit dynamically prevents power
amplifiers from being overdriven into hard clipping --
- which protects your speakers from potential
damage - - - which assures that the amplifier will pro-
duce its maximum output without increased distor-
tion. The power delivered is 100 watts per channel at
4 ohms to give extra dynamic life to your music •
even when you're using any combination of 3 sets of
stereo loudspeakers.
The selectively lighted dial pointer lights only the
relevant part of the tuning indicator to make tuning
easier.
Automatic AC power control is provided by the
auto On/Off circuit that conveniently shuts off the
entire system when the turntable shuts off. No need
to interrupt your pleasure at the end of the record.
Front panel tape recorder jacks allow simple plug
In of an "outboard" tape recorder without upsetting
your regular system connections.
Copies of tapes can be easily made between two
connected tape recorders. Front panel tape copying
controls function without disturbing other sound
sources.
This outstanding receiver will serve you best when
you understand its functions and what it is designed
to do. Some time invested with this manual will be
valuable in your knowledge of how it works.
