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. 

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 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.
