6 – Phantom Power Indicator
(48V)
This red LED illuminates when the Phantom
Power switch on the back panel is set to the “on”
position. 48V phantom power is sent to both of the
front panel microphone inputs when enabled.
7 – Front/Rear Input Buttons
These buttons let you select either the front or back
panel inputs for each channel. When the button is
out, Fast Track Duo uses the front panel input.
When it is pressed in, Fast Track Duo uses the back
panel input.
8 – Signal Indicators
The green LED indicates the presence of an audio
signal at the corresponding input. If you are send-
ing signal to the input and the Signal indicator does
not light, try increasing the Input Gain control for
the channel.
9 – Direct Monitor Button
This button switches Direct Monitoring on and off.
When Direct Monitoring is on, Fast Track Duo
provides a latency-free mix of the input signal and
the output signal of your music software. When
Direct Monitoring is off, you must use the moni-
toring option in your music software.
10 – Headphone Output
Connect your stereo headphones to this 1/4-inch
output. The headphone monitoring signal mirrors
the Line Output signal. Set the volume using the
Headphone Level control.
11 – Power Indicator
This green LED indicates that Fast Track Duo is
receiving power from the connected host com-
puter. When using Fast Track Duo with an iPad,
you will need to power it using the USB power
adapter that was included with your iPad.
