ANTENNA CONNECTIONS
The FM jack is a standard screw on F-type connector. The AM is a
push type. Strip ¼ inch of insulation off your AM antenna wires
and insert one wire end into each hole while holding the tabs
down. Release the tabs to lock in the AM antenna wires.

CONTROL OUTPUT / IR INPUT
Control Output - This connection is to be used for
controlling other equipment such as an external B&K
Components, Ltd. amplifier, projection screen, etc.
Connect your control cable to the Preamplifier Tuner
using a mono 3.5mm mini-jack shown at left. The plug
must be wired as tip (+) and he long barrel section (-).

Connect your control cable to the Preamplifier Tuner
using a mono 3.5mm mini-jack shown at left. The plug
must be wired as tip (+) and he long barrel section (-).
The Control output is programmable for each source in your system (see “Advanced Setup”).
However, the
Preamplifier Tuner provides the following factory preprogrammed setup that should serve for most standard
system applications
Control - HEADPHONE - On (+12 VDC) when the unit is on and not in Headphone mode, Off when the unit is off
or in Headphone Mode. This mode may be used for controlling external amplifiers or powered sub woofers in an
audio zone.
Note - The control output is capable of sourcing a maximum of 12VDC @200 mA. Check to see that the source
you are connecting to the control out requires 200 mA or less current.
WARNING - Not all manufacturers adhere to the +12 VDC control specification. Check to see if your
sources control inputs are +12 VDC compatible. Do not connect your Preamplifier control outputs to a
device with control inputs rated less than 12 VDC before checking compatibility with the manufacturer as
damage to your source may result.
IR Inputs - Your Preamplifier Tuner can be controlled by a directly connected IR repeater system in combination
with or in place of the supplied remote control. Connect your IR input cable to the Preamplifier Tuner using a
mono 3.5mm mini-jack shown above. The plug must be wired as tip (+) and the long barrel section (-). The input
is standard 38 kHz modulated IR type with a voltage range of +6 to +12 VDC.
