Make sure that the power cord is connected to a suitable AC wall out-
let. See "Connecting the Power Cord" on page 11 for more informa-
tion.
Make sure that the 01V POWER switch is set to the ON position. See
"Turning On the 01V" on page 11 for more information.
If you still cannot turn on the 01V, contact your Yamaha dealer.
Try adjusting the contrast. See "Display, Selected Channel Controls &
Meters" on page 16 for more information.
Make sure that the +48 V phantom power is turned on for that input.
If a phone plug is plugged into the same input channel, the XLR input
is disabled. See "Input Channel Overview" on page 40 for more infor-
mation.
Use the [SEL] buttons to select channels. See "SEL Buttons" on page
32 for more information.
Make sure that the GAIN control and PAD switch are set correctly. See
Gain and Pad on page 41.
Use the HOME pages to check signal levels. See "Metering Signal Lev-
els" on page 83 for more information.

(plus Return Rotary Controls)" on page 35 for more information.

sends 1 and 2. See "About the Aux Sends" on page 94 for more infor-
mation.
Probably because the inputs have been swapped. See "Swapping
Inputs 1–8 & 17–24" on page 51 for more information.
