3.5 Line Input Level Adjustment (RIGHT
SIDE)
The “LINE LEVEL IN” is a pot that is preset in
the factory to provide proper ALC action using
the TEN-TEC USB soundcard digital mode
adapter cable model 712. An adapter to convert
the 712 ACC connector pins to the 8 pin mic
input will need to be created. See the “507 – 712
Wiring Diagram” for proper wiring instructions.
This adjustment is visible in Figure 3.
3.6 Line Output Level Adjustment (RIGHT
SIDE)
This potentiometer adjusts the signal level to
the Line Output (pin 1) of the Microphone jack.
It is typically used with a soundcard interface,
such as the Ten Tec 712. After attaching a
soundcard interface adjust this potentiometer to
give an appropriate sound level as indicated by
the digital mode software. Note that there are
level controls in the soundcard driver and digital
mode software which also affect this level.
This adjustment is visible in Figure 3.
