IF-AV/DM
Aviom Pro16 A-Net Interface Card
TASCAM IF-AV/DM

NOTE
Using the A-Net out connector of, e.g. a A-16II Personal
Mixer to extend the signal does not supply power to the
additional units, which must be powered individually.
For long distance applications, fiber optic cable can be
used to span distances up to 50 miles (80 km) with the
use of devices called media converters. A media converter
changes the Ethernet-based Pro16 A-Net signal to fiber
optic at the source location and then back to Cat-5 at the
destination. Several companies make fast Ethernet to fiber
media converters that can be used with your IF-AV/DM and
Aviom equipment.
Mixer control screen
On both the DM-3200 and DM-4800, the IF-AV/DM
presents a setup display screen as shown below.
Navigate to the Digital page (LCD access button 2 with
blue
ALT
LED lit), and then select the
SLOT
tab (labeled
SLOT
1
-
2
or
SLOT
3
-
4
on the DM-4800)
Use the 4 arrow keys to the right of the LCD screen to move
the cursor over to the A-Net Card area. It may be on the left
or the right hand side of the screen, depending on which
slot the card is inserted into. Use the
ENTER
key to make
changes.
The
JOG/DATA
dial can also be used to move the cursor up
and down.
This display has the following:
STATUS
ª
This shows whether the IF-AV/DM card itself is working
correctly and the state of the A-Net.
CARD Status
OK
•
:
The IF-AV/DM is running at full 16 channel count.
Unsupported FS
•
:
The mixer is not running at 44.1 kHz or 48 kHz, so the
IF-AV/DM will not pass audio.
Not Responding
•
:
A problem was encountered during configuration.
A-Net Status
OK
•
:
The IF-AV/DM is connected to one or more A-Net
receivers.
xxx
•
Timeouts
:
A problem was encountered.
STEREO LINK
ª
Use the up and down arrows and then the
ENTER
button to
toggle the state of the channel pairs that you wish to link
or unlink. When linked, the display on the Personal Mixers
will change to show a stereo spread control instead of a
pan control for those two channels. The channel’s volume
will also be controlled as a pair. Compatible A-Net devices
that do not respond to stereo linking will not be affected by
changes to the Stereo Link status.
System clocking
Master clock
When configured with an IF-AV/DM, the mixer can have
any clock source as long as it is 44.1 kHz or 48 kHz. The
IF-AV/DM does not operate at the 2x rates of 88.2 kHz and
96 kHz, so when the mixer is running at these rates, the
A-Net output from the IF-AV/DM will be silent, and the
LCD screen will show “
Unsupported
FS
” for the A-Net
Status field.
Varispeed pitch
The DM-3200 and DM-4800 can run at non-standard
Sample Rates when locked to an external clock.
The IF-AV/DM will follow along up to the limits of the
mixer’s clock.
Here are the supported pitch ranges.
44.1 kHz : -6.0% to +6.0%
•
48 kHz: -6.0% to +6.0%
•
Outside of these ranges, the mixer will mute and report a
clock error.
DM-3200/4800 settings
The IF-AV/DM appears to the Mixer just like any other
optional I/O card except that it may have 16 channels of I/O
instead of 8 depending on whether the card is inserted into
slot 1 (or slot 3 for the DM-4800).
Mixer outputs
By default, the DM-3200/DM-4800 routes busses 1 – 16 to
IF-AV/DM outputs 1-16.
These routing settings can be changed in the
OUTPUT
SLOT
tab of the DM-3200/DM-4800’s
ROUTING
screen.
