Mytek FW DIO Card – User Manual Introduction The Mytek FW DIO Card is an optional card that is installed into the rear expansion slots of the Mytek 8X192 ADDA converter. With this card installed the Mytek 8X192 ADDA can be directly connected to a MAC OS or Windows computer via FireWire. The card may be installed by the user as described further in the manual. Before You Begin Before connecting the DIO-FW card please check if the most current firmware (version 4.5.
Mytek FW DIO Card – User Manual Quick Start 1. Installation of DIO-FW card Remove the top cover from the converter, unscrew the DIOCARD1 or DIOCARD2 slot plate and install the DIOFW card using the existing screws in either slot. If there is a Protools DIO card installed it will work in slot 1 only. All other DIO cards including Firewire will work in either slot. The card must be installed with the components facing down.
Mytek FW DIO Card – User Manual 4. Configuration On first power up of the converters, each converter should be recognized by the computer and have the driver installed automatically. Further configuration of inputs and outputs is done in your DAW software. In the Mytek Firewire Control Panel (Mac: in System Preferences) check if the desired sampling frequency is displayed and if the ADDA 8x192 converter is set as the clock source. If more than one converter is attached, each one will have unique name.
Mytek FW DIO Card – User Manual To install the DIO-FW card: 1. Check if the power cord and all signal and clock lines are disconnected. 2. Remove the top cover. 3. Locate the DIOCARD1 or DIOCARD2 expansion slot on the mainboard. www.mytekdigital.
Mytek FW DIO Card – User Manual 4. Unscrew the cover plate of the selected slot on the rear panel. 5. Partially insert the card from the back of converter. www.mytekdigital.
Mytek FW DIO Card – User Manual 6. Connect the card ribbon cable to the DIOCARD1 connector on the mainboard. Double check all pin alignment. 7. Gently push the card inside and secure it with four screws www.mytekdigital.
Mytek FW DIO Card – User Manual 8. 9. Attach converter top cover. Connect power and signal lines. 10. Turn the converter on. After boot up (which takes approx 20 sec) the converter will switch to regular mode, and FW DIO Card (DIOCARD1 or DIOCARD2) can now be selected as signal source for DAC. Typically “analog” would be selected as ADC source (see converter manual) www.mytekdigital.
Mytek FW DIO Card – User Manual Connecting Clock Signal Line Single converter If a single converter is used in the system, using it's internal clock will provide the best performance (regardless of what a clock dealer will tell you.) If external clock is used for systemic reasons SAMPLE RATE must be set to EXT. by pressing and holding EXT CLOCK SOURCE switch.
Mytek FW DIO Card – User Manual FireWire Chain Input Connection There are two FireWire ports on DIO-FW card. Either one can be used for computer connection. The second port can be used to daisy chain a second converter. Firewire connectors on the back of FW-DIO card. If several converters are connected, each must have a unique name. When the converter is turned on for the first time, it receives a name “8x192 ADDA”. In the case of multiple units the name can then be changed in the driver control panel.
Mytek FW DIO Card – User Manual Signal Routing Every connected ADDA8x192 converter provides the system with 8 input and 8 output channels. All channels are detected as a single Mytek interface. If more than two channels are used, audio software which understands multichannel I/O must be used. Channel routing is typically assigned in a dedicated hardware control panel of the audio software application. Mytek Driver Control Panel The Control Panel controls the converter's operating parameters.
Mytek FW DIO Card – User Manual Select 8x192 ADDA as the sync source, set the sample rate in the driver control panel to that currently used by audio software. Changing sample rate in the control panel will force the change on the converters front panel. Selecting 8X192 ADDA as sync source Selecting Sampling Rate www.mytekdigital.
Mytek FW DIO Card – User Manual Windows version of the Control Panel allows user to choose ASIO or WDM mode of operation. Generally start with WDM, and experiment with ASIO later. Mode selection screen In the WDM mode operating channels can be mapped to physical channels of the device. Input channels offer two options: Stereo or Direct. Input operating mode selection In the output channel selection more options are available. They include standard settings for the multichannel audio. www.mytekdigital.
Mytek FW DIO Card – User Manual Output operating mode selection You can now set how mode channels will be mapped to the converter's physical channels. Channel mapper www.mytekdigital.
Mytek FW DIO Card – User Manual Feasibility of driver's operation modes depends on the computing power at hand. If computer is too slow, dropouts will occur in the audio signal. Typically shortages of computing power are short and intermittent. Increasing data buffer size, and therefore the latency, would usually result in dropout reduction. This function has been implemented in the driver under different modes of operation: one normal mode and several “safe modes”.
Mytek FW DIO Card – User Manual On the right side of the Control Panel there is a box which lists converters and allows to choose the one which is about to be configured. The one providing master clock is marked by a clock icon. Master clock selection www.mytekdigital.
Mytek FW DIO Card – User Manual Card firmware update To perform firmware update of DIO FW interface card: 1. Connect 8x192 ADDA converter to computer via FireWire and turn it on. 2. Start Mytek control panel and press “Firmware Loader” button. 3. Choose “Show details” box. www.mytekdigital.
Mytek FW DIO Card – User Manual 4. Browse for firmware update file. 5. Compare versions of firmwares. If browsed file version is newer press “upload button”. 6. Wait until popup windows disappear 7. Restart 8x192 ADDA converter. The firmware is now updated. www.mytekdigital.
Mytek FW DIO Card – User Manual Mainboard firmware update This update might be necessary to bring the converter's main board up to date to allow its operation with the firewire card. Generally installed main board firmware should be of rev. 4.5.3 or greater. Contact Mytek via email to obtain current firmware chip.
Mytek FW DIO Card – User Manual 3. Locate the memory socket on the converter main board. 4. Gently remove old memory chip. To avoid damaging memory pins, remove the chip vertically. Retain old memory chip. www.mytekdigital.
Mytek FW DIO Card – User Manual 5. Carefully insert new memory chip in the socket. The chip slot (pin1) should be matching the socket slot ie must be facing back of the unit. If necessary gently manually bend pins inward, to match the holes in the slot. During installation check correct chip orientation. 6. Mount the top cover back. www.mytekdigital.
Mytek FW DIO Card – User Manual 7. Attach power cord and other cabling. 8. Turn on the converter. For about 2 seconds no LED should be lit on the converter’s front panel, as new software is copied from memory to the main board chips. Then, all LEDs should turn on momentarily for about 10-20sec, and subsequently the unit should begin normal operation.
