the Manual is used to perform, any service or repairs on any M-Audio product or part
thereof, any and all warranties of M-Audio as to that product and any service contract
with M-Audio for that product shall be voided and shall no longer apply for such product,

Test App
1. Input Gain
2. LED Meters
3. USB / Direct Blend
4. Headphone Level
5. Monitor Level
6. Power LED
7. +48V (Phantom Power) LED
+48V Phantom Power Test
1. Switch the +48V phantom power to the right (turning it on).
2. Confirm that 48V is present on pins 2 and 3 of the XLR jack using the multimeter.
3. The acceptable pass range is 45V to 52V.
4. Switch the +48V phantom power to the left to shut down phantom power function.
