McIntosh CR7 Owner's Manual page 8

FIGURES 1 and 2
These illustrate the interconnection of equipment to
provide remote control in one area, the main area. In
this configuration the CR7 becomes the center of con-
trol for a preamplifier, a Mclntosh remote controllable
tuner, a Mclntosh compact disc player and a power
amplifier. The Mclntosh CR7 provides switching to in-
terconnect and control the functions of these units.
Each diagram, from Figure 3 on, illustrates the expan-
sion of the basic system to additional areas. The
CR7/CR8 will provide facilities for up to 5 remote areas
in addition to the main listening area.
CONTROL CABLES
In the CR7 the infrared is decoded to control the
various tuner and compact disc functions. Provided
with the CR7 are two cables which conduct the con-
trol data from the CR7 to a Mclntosh tuner and a
Mclntosh compact disc player. The cable with the 15
pin computer type connectors on each end connects
the Mclntosh tuner to the CR7. Insert one end into
the REMOTE CONTROL socket on the tuner and the
other into the TUNER CONTROL socket on the CR7.
The captive screws on each end of the connector
must be tightened to prevent the plug from discon-
necting. The second cable has 7 pin DIN connectors
on each end. It connects the Mclntosh Compact Disc
Player to the CR7. Insert one end into the REMOTE
socket on the compact disc player and the other into
the CD CONTROL socket on the CR7.
AUDIO
Use shielded cables to connect between the signal
sources, the power amplifier and the CR7. To minimize
the possibility of hum the shielded cables should be of
parallel construction or loosely twisted together and
located away from speaker connecting cables and AC
power cords. Be certain to use good quality shielded
cables. Your dealer can best advise you on the kind
and length of cables that will best suit your installation.
OUTPUT L and R
The OUTPUT L and R jacks are connected to the
power amplifier input with shielded cable. Connect
the OUTPUT L jack to the power amplifier left input
and the OUTPUT R jack to the power amplifier right
input.
TUNER L and R
The TUNER L and R jacks are connected to a Mcln-
tosh tuner audio output with shielded cable. Connect
a cable from the tuner left channel audio output
6 CONNECTING
to the CR7 TUNER L jack. Connect a cable from the
tuner right channel audio output to the TUNER R jack.
CD L and R
The CD L and R jacks are connected to a Mclntosh
compact disc player with shielded cable. Connect a
cable from the CD player left output to the CD L
jack. Connect a cable from the CD player right out-
put jack to the CD R jack.
AC POWER:
Plug the AC power cord into a 120 volt 60 Hz wall
outlet. The plug blades arc polarized so be certain
the plug is fully inserted in the outlet to prevent
blade exposure.
CAUTION: TO PREVENT ELECTRIC SHOCK, DO NOT
USE THE (POLARIZED) PLUG ON THIS UNIT WITH
AN EXTENSION CORD, RECEPTACLE, OR OTHER
OUTLET UNLESS THE BLADES CAN BE FULLY IN-
SERTED TO PREVENT BLADE EXPOSURE.
Two types of AC power outlets are provided on the
back panel of the CR7. Two are black and one is red.
The black outlets are switched on or off when the CR7
is turned on or off. The red outlet is on at all times.
The power capacity of all the outlets is 1750 watts.
The AC power cord from the preamplifier must be
plugged into the PREAMP AC outlet on the rear of
the CR7. The AC power cord from the tuner and
compact disc player are connected to switched AC
outlets on the preamplifier.
The AC power cord from the power amplifier must
be plugged into the POWER AMP outlet on the rear
or the CR7.
REMOTE SENSOR
Should the CR7 front panel infrared sensor be hid-
den from view when installed, as in a cabinet, a Mcln-
tosh R607 Remote Infrared Sensor can be used. Figure
2 shows the addition of a Mclntosh R607 Remote Sen-
sor which can be fitted in an ordinary electrical switch
box and installed in the ceiling or wall. The R607 Re-
mote Sensor is connected to the CR7 Remote SYSTEM
SENSOR connector with up to 300 feet of RC-59/U
cable and a type F connector. Choose a location for
the remote sensor that will not be obstructed by fur-
niture, drapes, etc. and will not be exposed to exces-
sive amounts of daylight. Obstructions will interfere
with the "line of sight" infrared transmission from the
hand-held controller, while excessive infrared from
daylight can affect the performance and sensitivity of
the Remote Control System.
