McIntosh MI3 User Manual

SIGNAL STRENGTH (VERTICAL)
MULTIPATH CONTROL
This control adjusts the position of the Multipath
trace display along the vertical scale of the indi-
cator screen.
DEVIATION (HORIZONTAL)
MULTIPATH CONTROL
This control adjusts the maximum width of the
multipath trace display along the horizontal scale
of the indicator screen.
LEFT GAIN (VERTICAL)
AUDIO CONTROL
This control adjusts the maximum vertical indicator
trace deflection for a left channel audio signal.
RIGHT GAIN (HORIZONTAL)
AUDIO CONTROL
This control adjusts the maximum horizontal indi-
cator trace deflection from a right channel audio
signal.
SIGNAL STRENGTH INPUT (TP1)
This input connects to a Mclntosh tuner Test Point
No. 1, which supplies a voltage proportional to
Signal Strength for vertical deflection of the indi-
cator trace.
DEVIATION INPUT (TP2)
This input connects to a Mclntosh tuner Test
Point No. 2, which supplies a voltage pro-
portional to deviation of the FM trans-
mission for horizontal deflection of the
indicator trace.
LEFT AUDIO INPUT
This input connects to the left output of a
tuner, preamplifier, or power amplifier.
The left channel audio signal voltage
causes vertical deflection of the indicator
trace. This input jack is in parallel with the
left audio output jack.
LEFT AUDIO OUTPUT
This output jack is in parallel with the left
audio input jack. This parallel connection
makes it convenient for connecting a pre-
amplifier or tuner output to both the Ml 3
and the power amplifier.
RIGHT AUDIO INPUT
This input connects to the right output of a
tuner, preamplifier, or power amplifier.
The right channel audio signal voltage
causes a horizontal deflection of the indica-
tor trace. This input jack is in parallel with
the right audio output jacks.
RIGHT AUDIO OUTPUT
This output jack is in parallel with the right
audio input jack. This parallel connection
makes it convenient for connecting a pre-
amplifier or tuner output to both the Ml 3
and the power amplifier.
1A SLO BLO
A 1 ampere SLO-BLO fuse protects the
Ml 3 indicator circuits. This fuse does not
protect additional equipment connected to
the back panel AC outlets.
350 WATTS AC OUTLET
A 117 volt AC outlet is provided for extra
equipment drawing as much as 350 watts
power. The outlet is not fused and is on
whenever the Ml 3 power cord is connected
to an AC outlet.
