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.
IR Output - The Preamplifier has the capability to be controlled by an Infrared Data/Signal (see below). IR Data
detected from the Preamplifiers front panel, or the rear panel Data/Signal, are electrically ORed together and sent
out this IR Output mini-jack. The plug must be wired as tip (+) and the long barrel section (-). This connector may
be used as an IR blaster for further system control and interface applications.
CONTROL I/O
Control I/O - These connections are for use when interfacing other equipment such as Keypads, an external
amplifier, projection screen, etc. The PT5 allows connections to zone keypad/sensors via a 5 pin plug-in Phoenix
connector.
+12V - +12V Power to Keypad or IR Sensor
Ground - Common Ground
RS232 Xmit - RS232 One Way Transmit
Data In - Infrared Data/Signal
CTRL Out - 12V Programmable Control Out
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.
Control Out (CTRL Out) - The factory default CTRL Out settings is 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. The other Control Out (CTRL Out) option
settings are OFF, POWER and RS232.
The Control I/O CTRL Out pin 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. Connect your control cable to the Preamplifier using a mono 3.5 mm mini-jack
shown at left. The plug must be wired as tip (+) and the long barrel section (-).
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.
