may be necessary to "position" the antenna for best signal
reception. This should be done before it is permanently
located.
Avoid locating the antenna next to other wires or metal
objects. Any indoor antenna may be ineffective in houses
having metal siding or metal foil insulation.
AM ANTENNA
For local and most moderately distant AM reception the
built-in ferrite loopstick antenna may be used. The
loopstick is mounted on a swivel base and must be ad-
justed away from the chassis for best reception.
Distance reception can be improved with the use of a
copper antenna wire 50 to 150 feet in length. Suspend
the wire, horizontally, in a straight line as high as possible.
Attach the wire to an anchor at each end with suitable
glass or ceramic insulators. Connect a lead-in wire at a
convenient point on the antenna. Use a lighting arrester
for protection with an outdoor AM antenna. The arrester
should be well grounded to a ground rod or cold water
pipe.
HOW TO CONNECT A MclNTOSH EQUALIZER
POWER AMP IN and PREAMP OUT jacks are provided
on the rear panel for connecting a Mclntosh Environmen-
tal Equalizer, or other signal processing equipment. Con-
nect the left and right shielded cables from the signal pro-
cessor outputs to the Left and Right POWER AMP IN
jacks. Then connect shielded cables between the Left and
Right PREAMP OUT jacks to the equalizer inputs.
The input jacks are automatic switching jacks that
disconnect the preamplifier's output signal from the
power amplifier's input and connects the signal
processor's output with the power amplifier's input.
HOW TO CONNECT
ADDITIONAL POWER AMPLIFIERS
External power amplifiers may be fed from the
MAC 4200 in two ways:
1. Connect a shielded cable from the Left and Right
PREAMP OUT jacks to the Left and Right input of the
power amplifier. The PREAMP OUT jacks are affected by
the VOLUME, EQUALIZER, BALANCE and LOUDNESS con-
trols. Both the MAC 4200 amplifier and the additional
amplifier will be fed from the preamplifier. If the MAC
4200 amplifier is not going to be used, insert a pair of
non-shorting phono plugs in the POWER AMP IN jacks to
disconnect it from the preamplifier output.
2. The TAPE 1 or TAPE 2 OUT jacks may be used to
drive an external amplifier which has its own controls. The
output of these jacks is not affected by the VOLUME,
EQUALIZER, BALANCE and LOUDNESS controls on the
receiver. A suggested use would be to feed an amplifier
in a remote location where volume and tone re-
quirements need to be controlled at the remote amplifier
In this configuration, the TAPE 1 connections can not be
used for a tape recorder.
HOW TO CONNECT REMOTE SCAN
The remote scan switch/cable assembly plugs into the
rear panel REMOTE SCAN input jack. The cable assembly
is a Mclntosh accessory (Part No. 045-515} available from
your dealer.
