corresponding audio signals will be switched simultaneously.
VCR1: Connect cables from either the S or Standard VCR1 Video Output to the video in-
puts of a VCR.
VCR2: Connect cables from either the S or Standard VCR2 Video Output to the video in-
puts of a second VCR.
Use either S or Standard Video connectors for all inputs and outputs. Do not mix
connector types.
27. SUB WOOFer
This switch turns the subwoofer channel on or off in MONO, STEREO and HALL operating
model The subwoofer always operates in CINEMA 1 and CINEMA 2 modes, regardless of
this switch setting.
28. HIGH PASS FILTERS
Set the switch to ON to filter all low frequencies below 80Hz from the Left Front, Center
and Right Front speakers. This mode of operation is preferred when all three front speakers
are small and compact. A Subwoofer will then be necessary to handle all bass frequencies
of 80Hz and lower. Set the switch to OFF when full range front speakers are used. The HIGH
PASS FILTERS switch, functions in all operating modes.
29. 6 CHANNEL OUTPUT
This connector accepts a 25 conductor shilded subminiature "D" male-to-female com-
puter type cable that feeds all six program signals and the AC power control signal to the
matching 6 channel (THX) connector on the rear panel of a Mcintosh MC7106 Six channel
power amplifier. A single cable connection between a C39 and MC7106 makes an easy and
convenient installation for a Mcintosh Home Theater system.
30. DATA PORTS
The 14 DATA PORTS provide data signals to be fed to compatible audio and video ac-
cessories. This allows you to control the accessory components with their own remote con-
trollers transmitting to a C39 sensor.
The HOME DATA port is provided for connecting to the HC-1 Home Controller. This allows
you to control accessories such as lights or viewing screen motors.
The SUM DATA port is used for connecting to the Mcintosh Model RCT-1 Remote Control
Translator. Any IR signal transmitted to a CR39 sensor results in data signals at this port.
The RCT-1 is a learning device and will allow the C39 to remotely control most major brands
of accessory components.
All cables connected from the DATA ports use shielded wire with 1/8" mini phone
plugs. Connections are to the sleeve and tip of the plug.
Use either S or Standard Video connectors for all inputs and outputs. Do not mix
connector types.
31. EXTERNAL SENSORS (AREA "A" and AREA "B")
Connect a coaxial cable from the AREA "A" EXTERNAL coaxial connector to an R649 Wall
IR Sensor or WK-1 Keypad. This allows the C39 Remote Controller to send control signals
to the C39 for Area "A" functions without aiming it at the C39 front panel. An example would
be if the C39 were installed behind a cabinet door that would block the front panel sensor.
Connect a coaxial cable from the AREA "B" EXTERNAL SENSOR coaxial connector to
an R649 Wall IR sensor or a WK-1 Keypad installed in the remote Area "B". This allows you
to turn on Area "B" and select all the available system operating modes and program selec-
