Specifications
CONNECTING TO MclNTOSH MX110
TUNER-PREAMPLIFIER WITH M
SERIAL NUMBERS
Remove capacitor C130 (.005 MF) con-
nected between the test point and ground.
Solder the center lead of a 1 foot low-loss
shielded cable to the junction point of R139
(10K) and C125 (.1 MFD). Solder the outer
shield of the cable to the tuner chassis
ground. Use one of the 1 foot long low-loss
shielded cables, stripped and tinned on one
end, (female jacks on the other end) sup-
plied with the MI-2.
Use a connector with male plugs to con-
nect the soldered in cable from the tuner to
the Deviation (horizontal) Input on the MI-2.
Connect a 3 foot low-loss shielded cable
from the test point (on top of tuner chassis)
to the Signal Strength (vertical) Input on the
MI-2.
CONNECTING TO MclNTOSH MR65B
TUNER
Remove capacitor C27 (.005 MFD) con-
nected between TP1 and chassis ground.
MR65B tuners serial numbers 300U0 and
above do not have this capacitor.
Connect a 3 foot low-loss shielded cable
from the MR65B TP1 (Test Point 1 on tuner
back panel) to the Signal Strength (vertical)
Input on MI-2.
Connect a 3 foot long low-loss shielded
cable from the MR65B TP2 (Test Point 2 on
top of tuner chassis) to the Deviation (hori-
zontal) Input on the MI-2.
CONNECTING TO MclNTOSH MR65 and 65A
Remove capacitor C31 (.005 MFD) con-
nected between the test point and ground.
Connect a 3 foot low-loss shielded cable
from the MR65A Test Point (jack on top of
tuner chassis) to the Signal Strength (verti-
cal) input on the MI-2.
Connect a 3 foot low-loss shielded cable
from the MR65A MPX out jack on the tuner
back panel to the Deviation (horizontal) Input
on the MI-2.
If an external multiplex adapter is being
used with the MR65, a "Y" connector will be
needed in the MPX output jack. This allows
both the MPX adapter and the lead to the
MI-2 to be connected.
CONNECTING TO MclNTOSH MR66 TUNER
Remove capacitor C125 (.005 MFD) con-
nected between the test point and ground.
Connect a 3 foot low-loss shielded cable
from the TEST POINT (on top of tuner chas-
sis) to the Signal Strength (vertical) Input on
the MI-2.
Connect a 3 foot low-loss shielded cable
from the FM Multiplex output jack on the
tuner back panel to the Deviation (horizontal)
Input on the MI-2.
CONNECTING TO MclNTOSH MR55A TUNER
Remove the feed-through capacitor L43
(1000 MMF) connected to TP-1. This capaci-
tor can best be removed by unsoldering.
Solder the center lead of a 1 foot low-loss
shielded cable to the Test Point end of R27
(100K resistor). Solder the outer shield of
the cable to the chassis where the feed-
through capacitor was soldered. The cable
can feed through the hole in the chassis
where the capacitor was soldered. Use one
of the 1 foot long low-loss shielded cables,
stripped and tinned on one end, (female
jacks on the other end) supplied with the
MI-2.
Use a connector with male plugs to con-
nect the soldered-in cable to the Signal
Strength (vertical) Input on the MI-2.
Connect a 3 foot low-loss shielded cable
from the multi-out (multiplex output) jack on
the tuner to the Deviation (horizontal) Input.
If a multiplex adapter is being used with
the MR55A, a "Y" connector will be needed
in the MULTI-OUT Jack. This allows both the
multiplex adapter and the lead to the MI-2
to be connected.
CONNECTING TO MclNTOSH MR55 TUNER
Solder a wire across resistor R62 (1 meg)
connected to the test point on the tuner
chassis.
Connect a 3 foot low-loss shielded cable
from the test point on top of the tuner chassis
to the Signal Strength (vertical) Input on
the MI-2.
Connect a 3 foot low-loss shielded cable
from the MULTIPLEX OUTPUT jack on the
tuner to the Deviation (horizontal) Input on
the MI-2.
