Line 6 GearBox 3.1 – Basic Features Guide
S/PDIF Digital Out - To send the output of TonePort to an external device digitally, connect a
75-Ohm coaxial cable into this RCA jack and then into the S/PDIF digital input on the external
device. This is the best choice for connecting to digital recording devices, such as a DAT
recorder. This S/PDIF output sends the same audio as is sent to TonePort’s Analog Outs* (with
the exception that any audio coming into the TonePort’s Monitor In jack is not routed to the
S/PDIF output). The digital signal is always sent at 24-bit resolution.
Monitor In - If you want to hear the signal from a line level source mixed with all the other audio
coming from your computer, but do not want this audio recorded, then plug the source in here.
Note that this is a stereo jack, so you should use a stereo 1/4-inch TRS audio cable for this
connection.
Analog Outs - These Left and Right balanced jacks output all the audio from TonePort; the audio
from your audio software on the computer, and anything plugged into any TonePort input. So,
these are what you want to connect to your monitoring system when using TonePort as your
computer’s sound card. Use either 1/4-inch TS or TRS cables to connect directly to your powered
speakers, mixer or power amp setup. Note that you can also use the headphone jack on the front
of TonePort if you want to use headphones for monitoring.

Microphone Inputs - You can receive input from one or two mics at the same time using these
ins. There is also a +48V Phantom Power switch that you should toggle to “on” if your mic
requires phantom power (most condenser type mics do, but check the documentation for your mic
