ELECTRO MAGNETIC SWITCHING
Zero distortion, high reliability Electro Magnetic
Switches are used for all audio switching.
SERIAL DATA OUTPUT PORTS
A Serial Data Output Port is provided for each input
selection. In many instances this output can be
connected directly to a foreign piece of equipment
allowing it to be controlled through the Mclntosh
system.
REMOTE POWER ON AND MUTE INDICATION
On each keypad and remote sensor there is an LED
that lights when that area is POWERED and blinks on
and off when the area is MUTED.
NEW REMOTE SENSOR POWER SUPPLY
The design of the remote sensor power supply has
been changed to provide power to operate up to four
sensors or keypads wired in parallel on the same coax
line.
CONTROL CONNECTOR FOR POWER
In addition to the AC outlet that is powered when
any area is turned ON, there is a DIN connector that
provides parallel data to the Mclntosh PC-1 POWER
CONTROLLER. This POWER CONTROLLER provides
remote control of 5 AC outlets for AUDIO program
source equipment, 2 for VIDEO equipment, 3
unswitched and 4 for the four area POWER AMPLIFIERS.
The five outlets for the AUDIO equipment come on when
any area is powered, the VIDEO when any area selects
VIDEO and each POWER AMPLIFIER only when that
specific area is turned ON.
CASCADING CONTROLLER CONNECTORS
Two 25 pin subminiature "D" connectors are
provided. One is for the input of audio and control
signals, the other for output. This permits the extension
of the system to include more CR10s for additional areas
or for the inclusion of a full featured "MASTER" preamp.
VIDEO EXTENSION
For small systems the CR10 has a VIDEO input that
can be used for the audio from a stereo TV or VCR.
If more VIDEO capability is desired the Mclntosh MVS3
VIDEO AUDIO SELECTOR can be added. The MVS3
has Super VHS, normal VIDEO and AUDIO input
switching for 5 more program sources. Its audio output
is fed to the VIDEO input on the CR10. The VIDEO
Serial Data Output from the CR10 is fed to the MVS3
for switching control. With is arrangement one can
select TV, LASER, VCR1, VCR2 OR V-AUX from any
area. VIDEO signals or TV channel 3 or 4 can be sent
to other areas via coax cable. VIDEO switching is
arranged so that one can be recording or dubbing while
listening to any of the audio sources.
HOME CONTROL .
The CR10 System provides for expanding your
control to other devices in the home. With the use of
MHC1 HOME CONTROL MODULE one has 6 circuit
closures that are programmable for PUSH ON, PUSH
OFF, or MOMENTARY (push and hold) type of operation;
three circuit closures for PUSH ON, PUSH OFF only and
4 sequenced closures or openings operated from a single
button. Also included in the MHC1 is a 12VDC power
supply capable of delivering 1.5 amperes to these
contacts for operation of external relays etc. The
internal relays are sealed and have 20A, 240VAC
contacts.
Not only can one access the MHC1 from the CR10,
he can also operate it from up to eight keypads.
