Midi Connections; Audio Connections - Yamaha TX 816 Owner's Manual

For the basic
system you
will require:
*
A
Yamaha TX816
FM
Tone
Generator System.
*
A
Yamaha DX7
Programmable
Algorithm Synthesizer.
*A
high
quality eight
channel mixing console, with
at least
eight input channels.
(An
amplifier
with
two
inputs
would
be
sufficient for
the
TX216,
as
it
only has
two
audio outputs).
The
audio output
on each TF1
module
has an
impedance
of
600 ohms
and
is
rated
at
-lOdBm.
*
A
high
quality
power amp/speaker
system. Stereo
is
preferable, for
full
enjoyment
of
the
TX81
6's sight voices.
*Two
standard
MIDI
cables.
*
Eight
balanced
line
audio cables with
XLR
type connections. (For the
TX21
6,
two
cables
are sufficient).

The
TX816
receives highly
complex
information
via
MIDI
cables,
so only
MIDI
MIDI
CONNECTIONS
standard
DIN
cables
should be
used,
like
the
ones
that are
supplied with the
TX81
6.
If
you wish
to
purchase
further
MIDI
cables,
we
recommend
the
Yamaha MIDI-03
and MIDI
-1
5 cables (3 metres and
1
5 metres long
respectively).
MIDI
cables longer
than
15 meters should not be used, as the
MIDI
signal
can
deteriarate
if
sent over
too long a distance,
and
data
errors
may
result.
(a)
Make
sure that the
TX81
6
and
the
DX7
are
not
connected
to the
AC
supply.
Connect
the
MIDI
OUT
of the
DX7
to
the
COMMON
MIDI
IN
on
the front
of the
TX816 MIDI
rack frame. This enables the
DX7
to
send
MIDI
data
to
the
TX816, and
"play"
the eight voice
modules.
(b)
Connect
the
MIDI
IN of the
DX7
to
the
COMMON
MIDI
OUT
on
the
front
of the
TX816. This enables the
TX816
to
dump
voice data
into
the
DX7's
internal
memory.
Each TF1 module
in
the
TX816
has
a
balancaed
line
XLR
type output
on
its
rear
panel.
This connector
is
wired
in
the following
manner:
Pin
1
:
Shield: pin
2:
Hot:
pin
3
cold.
FM
digitally
generated voices are subtle
and
complex, and
we
recommend
that
you use
the highest quality of cables abailable to
connect your
TX81
6 audio
outputs
to
your
mixer,amplifier or
tape deck.
(a)
Make
sure that the
TX81
6 and your mixer
are
not
connected
to
the
AC
mains.
Connect
the
eitht
audio aouputs on
the
back
of the
TX816
to eight
line
inputs
on your mixer
(the inputs
must
be
suitable for a
600
ohm
signal rated
at
-10
dBm). The
easiest
method
is
to
connect
outputs
1
thru
8
of the
TX816
to
input
channels
1
thru
8 on your
mixer.
You
can adjust input channel
sensitivity
using the audio
Check
Signal,
as described
later in this
chapter.
(b)
As
an
option,
you can connect
hte
audio output
of
the
DX7
to
your mixer
if
you
with.
This
will
give
you
a total
of
nine voices
which can be
played
si-
multaneously.
However,
to hear
more
clearly
how
the
DX7
controls the
TX81
6,
it
is
better
not
to
use
this
option
to
begin with.
NOTE: The volume
control
lever
on
the
DX7
will
not
affect
the
volume
of the
TX816
voices.
