mLAN (IEEE 1394) connectors 1/2
For connecting mLAN devices or IEEE 1394-compatible
(FireWire/i.Link) devices via standard IEEE 1394 (6-pin)
cables. The operation is identical no matter which terminal
is used, mLAN 1 or mLAN 2. If the target device has a 4-
pin connector, use a commercially available 4-pin to 6-pin
IEEE 1394 cable. Avoid creating a connection “loop (page
147)” when connecting the devices.
y
ACTIVE lamp
This lights to indicate the 01X functions as an mLAN
device. Even if an mLAN cable is not connected, this
lamp stays lit. If an error occurs during mLAN operation,
the light turns off.
u
P48V switch
This switch supplies phantom power to MIC/LINE (XLR)
jacks 1 and 2. Turn this switch on if you are using con-
denser microphones requiring ex48V power with
MIC/LINE INPUT (XLR) jacks 1 and 2.
• Make sure to turn this switch off if a device not requiring an
external power supply is connected to the INPUT (XLR)
jacks 1 or 2.
• If phantom power is turned on, power will be supplied to
both INPUT (XLR) jacks 1 and 2.
i
DIGITAL STEREO IN/OUT jack
This is a coaxial jack (phono connectors) for digital input/
output of stereo signals. They conform to the IEC-60958
consumer format. For digital audio transfer, use an RCA
pin cable.
o
FOOT SWITCH jacks 1/2
Optional foot switches (Yamaha FC4/FC5) can be con-
nected here to control transport operations such as start/
stop. For example, when using remote control with the
SQ01, FOOT SWITCH 1 can be used to turn the [
>
]
(Play) button on/off, while FOOT SWITCH 2 can be used
to control on/off of the [
●
] (Record) button.
• The appropriate operation may not work if you use a foot switch
other than the Yamaha FC4/FC5 (or equivalent).

MIDI A IN/OUT terminals
MIDI B IN/OUT terminals
These terminals are for connection to external MIDI
devices. They allow you to transfer MIDI data between an
mLAN-connected computer and MIDI devices connected
to the 01X, making the 01X a convenient dual-port MIDI
interface for your computer. The MIDI A terminal corre-
sponds to mLAN MIDI port 2, and the MIDI B terminal
device corresponds to mLAN MIDI port 3 (page 95).
!1
DC IN terminal
Connect the AC adaptor (PA-300) to this terminal.
• Do not attempt to use an AC adaptor other than the Yamaha
PA-300 or an equivalent recommended by Yamaha. The use
of an incompatible adaptor may cause irreparable damage
to the 01X, and may even pose a serious shock hazard!
ALWAYS UNPLUG THE AC ADAPTOR FROM THE AC POWER
OUTLET WHEN THE 01X IS NOT IN USE.
!2
STANDBY/ON switch
This switches the power between ON and STANDBY
(off).
• Make sure to follow the procedures described in the “Setting
Up” section (page 24) when turning the power of the 01X on
or off.
• Even when the switch is in the “STANDBY” position, elec-
tricity is still flowing to the instrument at a minimum level.
When not using the 01X for an extended period of time, be
sure to unplug the AC power adaptor from the wall AC out-
let.

mLAN benefits
“mLAN” is a digital network designed for musical appli-
cations. It uses and extends the industry standard
IEEE 1394 high performance serial bus.
• Only one type of cable is needed, in contrast to the multiple vari-
eties required by conventional systems.
• MIDI and audio signal flow can be routed freely without being
limited by the actual cable configuration. Signal flow between
devices can be changed without having to physically reconnect
the devices.
• Cables can be connected and disconnected without turning off
the power (hot pluggable).
• The isochronous data transfer used by IEEE 1394 is a transfer
method that guarantees the right to transmit or receive data at
fixed intervals (125 microseconds). This is ideal for transfer of
realtime data such as audio.
