Falcon Interfaces
1
Analog
8/4 Interface
The Analog 8/4 interface provides the Falcon with eight or four
analog cinch outputs with
16-bit
precision (20
Hz
-
20
kHz).
It
is
directly
supported by
all
professional
HD
recording
systems (Cubase Audio, Logic Audio,
Audio
Master,
Audio
Tracker, Zero-X).
2
Power
supply
The Analog
8/4 Interface
uses an
external
power supply with 12
V,
500-1000
mA.
Polarity:
(-
ring,
+
tip).
Please
make
sure that the switch
is
set to 12 V.

How
to
connect the
interface to
the Falcon
Use
the special
SPDIF
adapter cable to
connect
the
Analog
8/4 Interface to
the Falcon.
The
SPDIF
interface
can be placed on top
of
the
Analog
8/4 Interface,
Use
the short
D-Sub connector
to
connect
the
SPDIF
port of
the Analog 8/4 Interface interface with the
SPDIF
interface.
Please connect the interfaces
in
the following order:
1.
ADAT
Interface
2.
Analog
8/4 Interface
3.
SPDIF
Interface

Combination
of
SPDIF
and Analog
8/4
In
some
cases the combination
of
an
Analog
8/4
and
a
SPDIF
interface of
the
first
revision
may
cause unexspected trouble during record. There
is
an easy
way
to
fix
this
problem:
1.
Open
the
SPDIF
interface
2. In
the top
right,
close
to
the connector you
will
find nine resistors.
The
last
one on
the
right
hand
side
is
a 18
Ohm
resistor
(brown/grey/black/gold).
3.
Replace this resistor with a
new
one
(68
Ohms
blue/grey/black/gold)

How
to
connect the interface to
the mixer
Use high quality
shielded
audio cables
to
connect the output
of
the
Analog
8/4 interface
with the input of
the audio mixer. Please refer to
the mixer's manual.
6
Software installation
The SoundPool Analog
8/4 interface
is
supported by
Cubase Audio
(Version 2.06 or
higher)
and AudioTracker (Version 1.60 or higher).
Other programs only support two
track playback.
For proper installation
and output selection refer to the
manuals
of the software.

Tips
&
Tricks
There
are various
sources
of
noise
and
hum
in
a studio.
7.1
Ground
loops
They can be
remedied
with galvanically
seperated line level
and
digital
connections.
Unfortunately the required transformers are quite
expensive.
We
therefore
recommend
optical
cables
(TOS
link)
for digital
connections and Dl-boxes with transformators for the
record
send (from the mixer to the computer).
Very often, this
is
sufficient. In
very
difficult
cases,
you can
find
very
good
articles
on the
subject
in
technical
magazines.
7.2
Digital
crosstalk
This
can be remedied with galvanically seperated
digital
connections
(optical cables)
and
very
good SCSI cables. Very often
you
will find the
power supply
of
some
devices to
be the
culprit.
7.3
Electromagnetic interference
Interference
by transformators
and power
supplies)
can be remedied with
balanced
cables.
This
effect
is
most noticeable with mircrophones (high
impedance and with high
