On the top panel of the Fast Track C600, begin
by turning the Gain knob fully counter-clock-
wise. As your sound source (instrument, voice,
etc.) is performing at its loudest levels, turn the
gain knob clockwise until the input level meters
are peaking within the yellow band of LEDs. The
red “Clip” LED (at the top of the meters) should
not illuminate as that means your signals have
overloaded the converters.
At this point, you have set optimum gain levels
and can begin recording.

If you are working with very loud sources and
the incoming signal is too loud even at mini-
mum gain levels (for example, when the Gain
knob is turned fully counter-clockwise), engage
the Pad switch. This will further reduce incom-
ing levels by approximately 20 dB to prevent
any distortion.
Connecting Instruments to
the Fast Track C600
Fast Track C600 provides two input types (DI
and Line) that correspond to the different signal
strengths output by different types of instru-
ments.
DI Inputs
These front-panel inputs are specifi-
cally designed for instruments such as electric
guitar or electric bass, which usually have a
lower output level and different impedance
than line-level devices.
Line Inputs Line-level devices, including elec-
tronic audio sources such as mixers, samplers,
keyboards, and synthesizers should be con-
nected to the Line inputs on the rear of the in-
terface.
