POWER CONNECTIONS
Once all input and output signal connections are made, you can
begin to make the power connections.
LINE 2 AND LINE 3 UMBILICAL CORD
CONNECTIONS
As the Line 2 and Line 3 each have an external power supply,
an additional connection is required. Plug the Power Supply
Umbilical cord (Y) from the rear of the Power Supply into the
Power Supply Input Socket (X) on the rear of the preamplifier as
shown below in figure 11.
PREAMPLIFIER POWER CONNECTIONS
Plug the detachable Power Cord into the Power Cord socket (N)
on the back of the LINE 1 chassis or power supply (LINE 2 and
LINE 3). The
LINE Series
preamplifiers are configured for the line
voltage in the country in which they are sold. See the shipping
box or the rear of the chassis for voltage settings. If a different
operating voltage is required, please contact an authorized
Sonic Frontiers dealer or the factory directly.

HOME THEATRE ACCESSORIES (OPTIONAL)
There are two external connections provided for customization of
you home theatre set-up. These are the I.R Jack (Infra Red) and
the Relay Trigger. Both of these connections accept a 3.5 mm
stereo plug as shown below.
I.R. JACK (INFRA RED)
The LINE Series preamplifiers allow you to install an external Infra
Red Repeater (user supplied). This will allow you to operate this
preamp from a remote location or different room in your house
via an Infra Red remote control. See specifications on page 13.
RELAY TRIGGER
If you have any automated devices, they can be activated by con-
necting here. The Relay Trigger is activated when the STANDBY
button is depressed (switching to OPERATE mode), causing an
internal, isolated relay contact (normally open) to close. This in
turn can be used to control the operation of your automated
devices (such as, turning off your listening room lights, drawing
your window curtains closed, cueing a projection TV screen or
projector to be lowered, etc.). See specifications on page 13.
