Troubleshooting
Symptom Advice
Cannot turn on the 01V.
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.
The display is difficult to read.
Try adjusting the contrast. See “Display, Selected Channel Controls &
Meters” on page 16 for more information.
Connected a condenser-type
microphone but it doesn’t work.
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.
The SELECTED CHANNEL PAN and
EQ F and G controls adjust the
wrong channel.
Use the [SEL] buttons to select channels. See “SEL Buttons” on page
32 for more information.
Input channel signal levels are too
low or too high.
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.

Cannot access input channels 17
through 24.
Input channels 17 through 24 are available only when an optional
Option I/O card is installed. See “About Option I/O Cards” on page
216 for more information.
Cannot select the HI-MID and
LO-MID EQ bands on input channels
17 through 24.
Input channels 17 through 24 feature 2-band EQ, so these bands can-
not be selected.
Cannot send signals from input
channels 17 through 24 to aux
sends 3 and 4.
This is correct. Input channels 17 through 24 can only be sent to aux
sends 1 and 2. See “About the Aux Sends” on page 94 for more infor-
mation.
Input signals 1 through 8 appear on
input channels 17 through 24.
Probably because the inputs have been swapped. See “Swapping
Inputs 1–8 & 17–24” on page 51 for more information.
Input signals are present but the
stereo output is dead.
Raise the STEREO fader and turn on the STEREO [ON] button. Make
sure that the input channels are routed to the stereo output. See
“Routing Input Channels” on page 49 for more information.
