Specifications

THX POWER AMP and other Mclntosh high power
amplifiers.
AUTO MUTING
The outputs are muted for 2 seconds during power
up to prevent hearing annoying clicks and pops
generated by other equipment.
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.
HOME CONTROL
The C39 provides for expanding your control to other
devices in the home. With the use of the HC1 HOME
CONTROL MODULE one has 6 circuit closures that are
programmable for PUSH ON, PUSH OFF. or MOMEN-
TARY (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 HC1 is a 12VDC power supply
capable of delivering 1.5 amperes to these contacts for
operation of external relays etc.
DOUBLE SHIELDED POWER TRANSFORMER
Copper and steel shielding eliminate hum pickup from
the power transformer.
ELECTRONICALLY REGULATED POWER SUPPLY
Regulators maintain stable operation even during
"Brown Outs" or low line voltage.
HEADPHONE JACK
A HEADPHONE JACK and amplifier are provided for
private listening. The jack is located behind the
motorized door.
MORE ILLUMINATED GLASS AREA
The front panel is all glass with control nomenclature
illuminated, even for the push buttons.
GOLD PLATED INPUT AND OUTPUT JACKS
Gold plating is chosen because of superior corrosion
resistance.
