Mytek Protools-HD DIO Card – User Manual
Introduction
The Mytek Protools-HD DIO Card is a physical card that plugs
into the back of the Mytek 8X192 ADDA converter.
With this card installed the Mytek 8X192 ADDA can be directly
connected to the Core, Process or Accel interface cards of
Digidesign Pro Tools HD ® systems.
The card may be installed by the user as described further in the
manual. The 8X192ADDA with the card installed will be
recognized by Protools HD® software as an emulated HD192
interface.
Before You Begin
Before connecting the DIO-HD card check if the most current
firmware (version 4.5.3 or later) is installed in the
8X192 converter. To verify the version locate the firmware chip
on the main converter board, or please contact Mytek for
additional assistance.
(If necessary contact Mytek to request appropriate firmware.)

Quick Start
1. DIO-HD card installation
Remove the top cover from the converter, unscrew
DIOCARD1 slot plate (first slot from the right while looking
at the rear panel) and install the DIO-HD card using
provided screws. Double check that all the connector pins
match properly with the pins of the connector on the main
converter board.
2. Connecting the card to Protools HD ® system
The Pro Tools card must be connected to the Primary Port of
the DIO-HD card. A maximum of two converters (which can
be of different brands) can be connected to each Protools
card. In the case of more than one converter, the second one
should be daisy chained from the Expansion Port of the first
converter to the Primary Port of the second.
3. Connecting the clock signal
The first converter in the Pro Tools system must operate on
internal clock and is the system clock master. We
recommend always making Mytek the master as it
incorporates a superior clock generator with multiple
wordclock outputs. When a 192 I/O Digidesign interface is
connected in the slave configuration, WCK on the front
panel of Mytek converter must be set to FS/4.
4. Hardware Setup Configuration
Choose Setup > Hardware Setup and check sampling
frequency, clock signal (should be set to Internal) and
confirm Input and Output interfaces are present. Every
converter in the menu should be Set to Default
Remember to turn off
power, and disconnect
power and signal cables
while working with the top
cover removed.
Turn down the amplifier
and speakers connected to
the computer while
launching the Pro Tools
application.

5. Routing configuration within converters
The Mytek 8X192 ADDA SOURCE TO DIGITAL OUT
defines sources of audio signals that are sent from the
converter to the ProTools system and all other digital
outputs (all digital outputs are simultaneous). SOURCE TO
ANALOG OUT defines sources of audio signals that are
transmitted to the DAC in the converter.
6. I/O signal configuration
In Setup > I/O Setup you can assign signal sources to
interfaces.
7. Input selection – start of recording
Choose preconfigured inputs and outputs in Pro Tools, test
record, and then playback of selected audio tracks.
Remember that 8x192
ADDA converter has eight
channels. Selecting
channels 9-16 as audio
sources will result in no
signal (digital silence).

Connecting Clock Signal Line
Single converter
If a single converter is used in the system, choosing internal
clock is the best solution. If external clock is used for
synchronization, SAMPLE RATE must be set to EXT. To do this,
press and hold EXT CLOCK SOURCE switch.
Regardless of synchronization source, choose in Pro Tools
software: Setup > Hardware Setup and select Internal on the Clock
Source tab.
Master 8x192 ADDA converter’s front panel
Clock source is typically internal, choose external only if you must
use it for systemic reasons.
Check if the selected sampling frequency of the converter (FS)
matches the sampling frequency in Pro Tools. If FS is double or
quadruple of external clocks frequency, WCK option must be set
to FS/4. FS/4 is the default setting and must be used whenever
multiple Digidesign I/O units are used in addition to master
8X192ADDA.

Multiple converters
A Protools HD system can accept up to two converters
connected to each card. Various brands can be mixed as long as
they are all capable of emulating the Digidesign HD192 I/O
interface. If multiple converters are used, one serves as a source
of the clock signal (Master), with the rest of the devices receiving
it (Slave).
Our recommended setup is to use the Mytek 8X192ADDA as
the clock source feeding all other converters from multiple
wordclock outputs to all slave devices in a star configuration.
8X192 ADDA converter has 6 clock outputs. Clock signal
originates from the very precise CX797 module. Because of
that 8X192 ADDA converter is the best clock signal source
in the majority of multiple devices configurations
Wordclock connections in a Protools HD system with 3 Mytek 8X192
ADDAs
In system with multiple
units, double check that the
configuration of clock signal
lines, synchronization
sources and sampling
frequency’s of all converters
in the system are correct.
Correct clock configuration
is necessary for proper
operation of converters and
for best sound quality.
Make 1st Mytek in the chain
the clock master for the
whole studio. There is no
benefit of using a dedicated
house clock generator.
Clocking off Mytek internal
clock generator produces
superior results because the
clock and clock line high
current drivers are the best
in the industry.
Changing external
synchronization source
while the program is
running may result in
improper operation of
converters and loud cracks
in the analog section.

Input Connection
The Protools DIO-HD card features two connectors: Primary
Port and Expansion Port. Functionality of these connectors is
identical to Pro Tools system. Up to 8 8X192 ADDA Mytek
Digital converters can be daisy chained or mixed with
Digidesign HD-192 and other brands that emulate an HD-192.
Output connectors on the back of Ptools-HD-DIO card.
Protools computer interface card should always be connected to
the Primary Port in the Master device, which operates as a clock
signal source. Then, Expansion Port can be connected with
Primary Port of a different Slave device. Devices are visible in
Setup > Hardware Setup menu of the Pro Tools application.

Signal Routing
While Protools software allows for up to 16 channels of input or
output, only 8 inputs and outputs are active when Mytek 8X192
ADDA is used.
Input
Audio signals transmitted from the 8X192 ADDA converter
originate from the source selected by the switch SOURCE TO
DIGITAL OUT. If ANALOG is selected, 8 analog channels will
show up as inputs in Protools software. If AES/EBU is selected,
8 digital channels will be present as inputs (only 4 if dual wire
AES/EBU mode is used!). Similarly other types of digital inputs
depending on the second DIO CARD2 installed can also be
used. If DIO CARD1 is selected as input, signal output from
Protools will be routed back into Protools inputs. The actual
signal flow in the 8X192ADDA is available in a form of
schematics in the 8X192ADDA manual.
After selecting channel sources in the converter, you can choose
channels selected for recording in the Pro Tools application. In
Setup > I/O Setup you can freely assign track sources to each
interface channels and then assign them to particular tracks.

Mytek Protools-HD DIO Card – User Manual
Output
To playback signal from Protools to the converter's analog
outputs DIOCARD 1 SOURCE TO ANALOG OUT should be
selected. If SOURCE TO DIGITAL OUT is set to DIOCARD1 as
well audio is relayed from the Pro Tools system to the converter
DAC (analog out) and to AES/EBU outputs as well as other
digital outputs if installed.
The actual signal flow in the 8X192ADDA is available in the
form of schematics in the 8X192ADDA manual.
The Protools tracks to be sent to the 8X192 ADDA can be
selected in the ProTools software. In Setup > I/O Setup you can
assign interfaces to signal outputs, later assigned to tracks in the
Pro Tools application.
While track outputs are assigned to channels in the Protools
software, the actual signal routing of the incoming 8 channels to
the converter's physical inputs and outputs must be done
manually on the converter front panel ( SOURCE TO ANALOG
OUT and SOURCE TO DIGITAL OUT). This routing may
initially appear confusing, but after studying the signal flow
diagram in the 8X192ADDA manual you will find it makes a lot
of sense by providing very useful system flexibility.

Launch and Configuration
After the card installation in the converter, and after each
hardware configuration change, interface controls must be
configured in the Pro Tools application during the first launch.
This is performed the following way:
1. Double check the cables connecting the converter with
the Pro Tools card are properly attached.
2. Turn the converter on.
3. Check if clock signals are properly configured and active
(solid lock, in case they are transmitted from an external
device).
4. Launch the Pro Tools application.
5. In Setup > Hardware Setup check if attached converters
were properly detected. 8X192 ADDA Mytek Converter
with Protools DIO-HD card is detected as 192/IO in the

If the converter is not attached to the Pro Tools systems, it can
be used as a standalone device as if no DIO-HD card was
installed. The DIO-HD card is disabled until it is connected to
the Pro Tools systems and the application is launched on a
computer.
When the application is launched, control over converter’s
sampling frequency is assigned to software. It is the only
available option in Setup > Hardware Setup which influences
converter’s configuration. Other settings, such as selection of
input or format of digital signal are ignored and should not be
changed. Before launching the application pay special attention
to clock signal source setting in the converter.
Remember that 8x192
ADDA converter has eight
channels. Selecting
channels 9-16 as audio
sources will result in no
