Chapter 4: Using Fast Track Duo
Setting the Output Level
Once the Fast Track Duo Line Outputs have been
connected to a mixer, amplifier or powered moni-
tors, the overall output volume is controlled by the
Output Level control on the front panel.
Recording Microphones
Use the Front/Back Input buttons to select the cor-
responding front-panel input connection. Then
connect a microphone using a standard XLR mi-
crophone cable to the corresponding front panel
XLR input.
If you are using a microphone that requires phan-
tom power, activate the back panel 48V Phantom
Power switch after connecting a microphone to
one of the front panel inputs.

In your audio software, select the appropriate Fast
Track Duo input (1 or 2) as the source for the track
you will be recording to. Adjust the Channel Gain
knob until you have sufficient audio signal without
clipping.
Recording Instruments
Use the “Front/Back Input” buttons to select a
front panel input connection or a back panel input
connection. Then connect an electric guitar, bass,
or other instrument using a standard 1/4-inch in-
strument cable (use a TS cable for instrument level
signals or TRS cable for balanced line level sig-
nals).
In your audio software, select the corresponding
Fast Track Duo input channel (1 or 2) as the source
for the track you will be recording to.
Setting Recording Levels
To set the gain levels for an input channel, turn the
corresponding Channel Gain knob fully counter-
clockwise. While the sound source is playing at its
loudest levels, slowly turn the knob clockwise un-
til the green LED of the Signal Indicator for the
channel begins to illuminate. Adjust the control so
that the green Signal indicator remains lit, but so
that the red Clip indicator does not light. At this
point, you should be ready to record with the opti-
mum gain setting.
Be sure to turn down all monitoring levels
before powering on your Fast Track Duo and
using it with headphones or loudspeakers.
Although phantom power can be used
safely with most microphones, it is possi-
ble to damage some ribbon microphones.
Always turn off phantom power and wait
at least ten seconds before connecting a
ribbon microphone.
Refer to the documentation for your
microphone for more information about
its power requirements.
