Audio and MIDI Interfaces
The
audio
functions
of
NeON
are
accessed
through
control
panels
on
the
host
PC.
There
are
no
front
‐
panel
features
to
control
audio
or
MIDI
interface
functions.
Audio Outputs
NeON
provides
stereo
line
outputs.
These
output
levels
are
controlled
from
the
host
PC.
The
headphone
outputs
are
independently
controlled
by
the
volume
output
control
on
the
rear
panel
of
NeON.
Audio Inputs
NeON
has
4
inputs.
2
are
line
inputs.
One
is
a
Mic
input
calibrated
for
low
‐
level,
low
‐
impedance
microphone
inputs.
The
last
input
is
a
Hi
‐
Z
(high
impedance)
input
suitable
for
guitars
and
other
Hi
‐
Z
gear.
MIDI
NeON
provides
MIDI
input
and
output
jacks,
which
are
independent
of
the
NeON
keyboard.
USB
is
capable
of
transmitting
more
than
16
MIDI
channels.
The
USB
‐
MIDI
specification
specifies
MIDI
“cables”
to
identify
independent
streams
of
MIDI
data.
MIDI
input
is
routed
on
cable
1
on
the
USB
bus
(NeON’s
keyboard
uses
cable
0).
MIDI
output
should
be
routed
on
cable
0.
Swapping MIDI Out port
NeON
provides
MIDI
output
from
2
sources,
one
is
USB
MIDI
Out
from
the
host
PC,
and
the
other
is
internally
from
the
keyboard.
You
can
swap
between
USB
MIDI
OUT
and
Keyboard
MIDI
Out
port
on
the
rear
panel
by
pressing
SHIFT
+
3
(Numeric
Button).
If
NeON
is
powered
up
without
a
USB
cable
attached,
it
defaults
to
sending
the
keyboard
data
through
the
MIDI
Out
port,
allowing
stand
‐
alone
mode.
When
a
USB
cable
is
connected,
the
MIDI
Out
port
is
automatically
connected
to
the
USB
cable.
Note
:
Two
MIDI
Out
sources
can
not
be
used
simultaneously.
Use
SHIFT
+
3
to
switch
between
the
2
MIDI
Out
sources.
Power
NeON
is
powered
from
the
USB
bus
and
draws
350mA.
An
external
AC
adapter
can
be
used.
This
adapter
should
have
a
9
‐
12VDC
output.
Note
:
AC
adapter
is
not
included.
We
recommend
a
9V
DC
adapter
that
draws
500mA.
