Figure 2. Various Forms of Multipath Reception

As They Appear on the MI-2 Display Screen.

Such a change may be as little as a fraction

of a foot or as much as several feet.

The MI-2 is also a very effective tuning

indicator:

1) Signal strength is shown by the vertical

position of the display trace. The higher

the position of the trace the greater is

the signal strength.

2) Correct tuning occurs when the display

trace is centered horizontally on the

screen. Since the display trace effec-

tively follows the tuner I.F. response

curve, centering the trace tunes the

detector to the center of the I.F. curve.

The Mclntosh MI-2 Multipath/Tuning Indi-

cator is a versatile instrument. Its usefulness

has been extended to show other signal volt-

ages. By turning the SCOPE TEST switch to

the L & R AUDIO position the MI-2 shows the

stereo or monaural character of the audio

signals).

1) A trace display along the L+R line will

occur with a monaural program source.

2) A trace display along the L-R line will

occur with a monaural program source

if the phase of one channel is reversed.

3) A vertical trace indicates that the pro-

gram is being delivered to the left

channel only.

4) A horizontal trace indicates that the

program is being delivered to the right

channel only.

5) Operating the balance control on your

tuner-preamplifier or system preampli-

fier can change the slope angle of the

L+R or L-R display.

6) A stereo program will be a complex and

varying circular or elliptical display of

irregular outline that depends on chan-

nel separation or on the phase ampli-

tude relation of the Left and Right

channel.
