Front Panel Controls and Connectors

1. Microphone Input
Mic-level input on balanced XLR connector. This connector is only active when the Front/Rear Input Selector (5) is set to "Front" (OUT
position). Input from this connector appears in your DAW software as a mono signal on the left side of the stereo input pair.
2. Clip indicator
3. Phantom Power Indicator
This indicator illuminates when the Phantom Power Switch (9) is pressed, indicating that +48VDC power is being applied to the Mic
Input (1).
4. Microphone Input Gain
This knob controls the amount of gain at the Microphone Input (1), over a range of 0dB to +40dB or greater.
5. Front/Rear Input Selector
6. Guitar Input
Instrument-level input on unbalanced 1/4" phone connector, for use with guitars, basses or other instrument-level sources. This connector
is only active when the Front/Rear Input Selector (5) is set to "Front" (OUT position). Input from this connector appears in your DAW software
as a mono signal on the right side of the stereo input pair.
7. Clip indicator
This LED illuminates when the Guitar Input signal level exceeds –1 dBFS. If the Clip Indicator glows steadily, reduce the Guitar Input gain
level (8).
8. Guitar Input Gain
This knob controls the amount of gain at the Guitar Input (6), over a range of 0dB to +30dB or greater.
9. Phantom Power Switch
This switch activates the +48V phantom power, for use with condenser mics requiring external power. When Phantom Power is active, the
Phantom Power Indicator LED (3) lights up.
NOTE: It is safe to connect most modern dynamic microphones or line level devices to the channel inputs when phantom power is
activated. However, some older ribbon microphones may be damaged by phantom power, and certain unbalanced line level devices may
malfunction or produce an audible hum when phantom power is active. Consult the documentation for these devices if you are unsure
how to proceed.
10. Output Level Control
This knob controls the amount of output gain to the rear-panel Line Output (18) and the front-panel Headphone Output (11).
11. Headphone Output
Stereo 1/4" TRS phone jack output for connection of headphones for monitoring the output signal. The volume level is controlled by the
Output Level Control (10).
12. Power Indicator
This LED illuminates when the FireWire Solo is powered on, either via bus power or the AC adaptor.
