5. INSTRUMENT LED
Lights when a 1/4" plug is inserted into the Instrument jack on the right
side panel.
6. STEREO BUTTON AND STEREO LED
This button toggles between Stereo mode and Mono mode for the Mic/Line
1 input (or Instrument input) and Mic/Line 2 input. The LED lights when
Stereo mode is on.
In Stereo mode (Stereo LED is on), the Instrument and Mic/Line 1 input
signals are sent to the Left Main Out, while the Mic/Line 2 input signal is
sent to the Right Main Out.
In Mono mode (Stereo LED is off ), each pair of input signals is mixed
together and sent to the Left and Right Main Outs as a mono signal. One
pair includes Instrument or Mic/Line 1 and Mic Line 2.
This does not affect the signal that is sent to the computer.
7. 48v LED
Lights when phantom power is active for the Mic/Line 1 and 2 input pair.
Phantom power can be turned on for the combi-jack input pair via the 48V
buttons on the back panel. Dynamic microphones do not require phantom
power to operate. Most condenser microphones do require phantom power
to operate. If you are unsure about the phantom power requirements for
your microphone, consult your microphone's documentation or contact the
manufacturer.
8. MIC/LINE 2 GAIN KNOB
Adjusts the input gain level for Mic/Line 2.
9. OUTPUT LEvEL KNOB
Controls the Left and Right Main output level.
10. MONITOR MIx KNOB
The IO 22 unit gives you the ability to hear your analog input signals
directly and immediately while recording without having to adjust levels
in software and before the delay caused by digital converters and computer
recording latency. This zero-latency analog monitoring is controlled by the
Monitor Mix knob, which you can use to adjust the blend between the
live analog inputs (called "Direct") and any sounds coming back from the
computer via USB ("Playback"). To hear only the live source input signals
plugged into the IO 22, turn the Mix knob fully left to Direct. To hear only
the mix from the computer, turn the Mix knob fully right to Playback. The
output from the Monitor Mix control is routed to the Main outputs and
Headphone outputs.
11. USB LED
Lights when a USB connection is detected.
