CONTROLS
1POWER switch
Press to turn the power on (OPT./COAX. position) or
off.
• Regardless of the OPT./COAX. switch setting, the
input is switched automatically to the Dolby Digital
RF input when ever a Dolby Digital RF signal is
input.
2POWER indicator
Lights (red) when the power switch (1) is set to ON.
3RF LOCK indicator
Lights when a Dolby Digital (AC-3) RF signal is input
to the AC-3 RF INPUT jack (5)
4DIGITAL OUTPUT COAX. (coaxial) jack
Connect this jack with the AC-3 DIGITAL IN jack of
your Dolby Digital (AC-3) decoder or receiver.
• When there are simultaneous inputs from the RF
INPUT (AC-3 RF) jack and DIGITAL INPUT (OPT.
/ COAX.) jack, the RF INPUT (AC-3 RF) signal is
output with priority.
5AC-3 RF INPUT jack
Connect this jack to the AC-3 RF OUTPUT jack on
your LD player.
6DIGITAL INPUT COAX. (coaxial) jack
Connect with the COAXIAL OUTPUT jack of your LD
player.
7DIGITAL INPUT OPT. (optical) jack
Connect with the OPTICAL OUTPUT jack of your LD
player. BE sure to remove the cap before using this
jack.
8DC IN (12V) jack
Connect the inlet type power cord from the provided
AC adapter. Do not plug the power cord into the wall
outlet until all other connections have completed.

CAUTION: For continued safety,
replace safety critical compo-
nents only with manufacturer's
recommended parts (refer to
parts list). indicates safety criti-
cal components. For continued
protection against risk of fire,
replace only with same type and
rating fuse(s). To reduce the risk
of electric shock, leakage-current
or resistance measurements
shall be carried out (exposed
parts are acceptably insulated
from the supply circuit) before the
appliance is returned to the cus-
tomer.
The DC voltage is an actual
reading measured with a high
impedance type voltmeter. The
measurement value may vary
depending on the measuring
instruments used or on the prod-
uct.
