Back Configuration:
USB Port:
This connection is used to connect the PJ7 to the computer running your CAD software. A USB
cable is included with the PJ7 module. Power is provided from the computers USB port so
external powering is not necessary unless running the 10W powered speaker output.
External Speaker Line Level Output:
The external line level audio output is designed to feed a self-powered speaker, such as computer
speakers. It is a stereo output and can be configured as either Per-volume or post-volume. If pre-
volume then adjustments from the front volume control will not affect the speakers level. If
post-volume then it follows the front volume adjustment. The configuration is covered in the
next section.
This output is not intended to directly drive a speaker, it is a low-level line level output.
Ex12V:
The ex12V power jack is used when utilizing the in10W speaker output. If using
external power you will need to move the internal/external power jumper (located directly behind
the power jack) and apply a center positive power supply. The power supply will need to be
rated at 3A to handle the audio level out the speaker.
