1. External DC power input - 2-pole barrel socket. 9V DC, 1.75A (max), positive on the external pole. When
iRig Pro Quattro I/O is connected to a Lightning iOS device, using this DC In with the optional PSU (included
in Deluxe version) will charge the connected iPhone or iPad.
2. Power switch - 3 position switch. Turns the power on and off.
3. External micro-USB power input - powers up the unit by using an external USB power supply capable of
providing 5V DC and at least 1A (performance may vary depending on micro-USB cable used: cable size
22AWG or greater is recommended).
4. Host port - mini-DIN connector - connect the iRig Pro Quattro I/O to your host with the supplied cable.
5. Battery level meter - this meter displays the remaining level of the internal AA batteries. When batteries are
not in use, only the HIGH LED is on.
6. 48V phantom power LEDs - these LEDs illuminate when phantom power is active for inputs 1-2 and 3-4.
7. Input meters - each input has a dedicated 5-segments peak meter, with 1-second hold on CLIP, that
indicates the level of the input signal. The red Clip LED will illuminate when your input signal reaches -0.1
dBFS. Use the gain controls to keep the signal below this level.
8. Output meters - these meters display the signal level received back from the host. These meters have the
same range as the input meters (-50 dBFS to -0.1 dBFS).
9. Built-in microphone - iRig Pro Quattro I/O’s built-in omnidirectional microphone capsule is located at the
top of the front panel. When using the built-in microphone, orient the capsule towards the sound source
being recorded.
