How To Connect 8 - McIntosh C34V Owner's Manual

The green AC power outlet is on at all times and
is used for turntable power. Do not use this outlet
for any other purpose. When the turntable power
cord is plugged into the green AC outlet, the turn-
table can be used as an alternate way to switch the
AC power to the entire system on or off. When the
turntable power is turned on, a sensor circuit in the
C 34V will detect the current drain of the turntable
motor and will turn on the C 34V the same way the
red POWER pushbutton does. The red power
pushbutton must be in the OFF or out position. As
long as a turntable is connected to the green AC
outlet, the turntable current will always override the
red POWER pushbutton and turn the system on.
Some turntables draw the same or very nearly the
same current whether on or off. AUTO TURN-ON
control is not possible with this type of turntable.
Use one of the red unswitched AC outlets instead of
the green.
13. FUSE:
A 1.0 AMP fast-acting fuse protects the C 34V
turntable current sensing circuits and the green AC
turntable outlet. This fuse must be replaced with the
same type and rating 1.0 AMP fast-acting fuse. Do
not use SLO BLO fuses. The fuse does not protect
equipment connected to the black AC outlet.
14. OPTIONAL ACCESSORIES:
ADDITIONAL AC POWER AND SPEAKER
SWITCHING WITH THE SPEAKER CONTROL
RELAY
The SPEAKER CONTROL RELAY, or SCR 2, is
designed to provide both speaker control switching
and high power switched AC outlets.
The SCR 2 also has two AC power outlets that
provide additional capacity of 2400 watts switched
by the C 34V. Use these outlets to supply AC power
to amplifiers or other components when the total
load switched exceeds the C 34V rating of 1440
watts. Plug the 4-prong plug on the cable attached
to the SCR 2 into the SCR 2 socket on the rear of
the C 34V. Plug the SCR 2 heavy, AC power line
cord directly into a wall outlet. Do not plug it into
the C 34V. When the C 34V is turned on, power
from the C 34V will energize a relay in the SCR 2
which connects the two SCR 2 AC outlets directly to
the wall outlet.
Two loudspeakers can be turned on or off with the
SCR 2 by using the front panel pushbuttons SPEAK-
ER/OUTPUT 1 and 2. Use the TO MAIN SPEAKERS
terminal strip to connect the main listening pair of
10 HOW TO CONNECT
speakers and TO REMOTE SPEAKER terminal to a
remote area pair of speakers. Connect the power
amplifier output to FROM POWER AMPLIFIER ter-
minal strip. Maintain left and right orientation and
like polarity. Pushbutton SPEAKER 1 will turn the
main speakers on or off and SPEAKER 2 pushbutton
will turn the remote speakers on or off.
15. VIDEO SELECTOR:
The Mclntosh VIDEO SELECTOR, MVS-1, is
designed to enable the C 34V to control video pro-
grams as well as audio. The MVS-1 connects to the
VIDEO SELECTOR computer-type connector on the
rear of the C 34V. Follow the instruction packet
with the MVS-1 for connecting the video cables,
