PERFORMANCE TIPS & TROUBLESHOOTING
110
on the 2408mk3 must match the sample rate of the
DAT. There are many possible configurations.
There must only be one master!
Clicks and pops due to hard drive problems
If you have checked your clock settings and PCI
bandwidth and you are still getting clicks and pops
in your audio, you may have a drive related
problem. Set your Clock Source to PCI-424
Internal and try recording just using the analog
inputs and outputs of your audio interface. If you
encounter the same artifacts you may want try
using another drive in your computer. Clicks and
pops can also occur when the drive is severely
fragmented, the disk drivers are outdated, or if you
are using a SCSI accelerator that is not optimally
configured for working with audio.
Connecting or powering gear during operation
It is not recommended that you connect/
disconnect, or power on/off devices connected to
the PCI-424 system while recording or playing
back audio. Doing so may cause a brief glitch in the
audio.
Digital Time Piece - erratic transport behavior
If you experience erratic transport behavior when
using Control Track sync from a Digital Timepiece,
be sure that the ADAT sync connection to the
PCI-424 is not plugged in. ADAT sync to the
PCI-424 is not required when using control track
sync and may interfere with DTP operation.
Yamaha 02R/03D - Yamaha TDIF card and the
2408mk3
You must have Yamahas version 2.0 TDIF card
which is identified by “CD8-TDII” indicator on the
outside of the card. Contact Yamahas service
department at (714) 522-9000 if you do not have
this card. Set DIP switch #8 on the card to “DA-88
EXT.
If you are connecting Tascam units like the DA-38/
88/98 via TDIF to the 2408mk3 along with a TDIF
connection from a Yamaha TDIF card, be sure to
put the Tascam unit into Bank A with the TDIF
card connection to bank B or C. If you are not
connecting a Tascam device, it doesn’t matter
which bank the TDIF card connection goes to.
Bus mastering - computers with six PCI slots
The PCI-424 card is a bus mastering device due to
the high bandwidth it uses on the PCI bus. On a
computer with six PCI slots, there are two PCI
busses: slots 1-3 are assigned to one bus while slots
4-6 are assigned to the other. If possible, you
should place the PCI-424 card on a bus that is not
being shared with another bus mastering device.
You may want to consult your computers technical
supplement for slot numbering.
MOTU PCI Audio Console is blank
The bottom half of the MOTU PCI Audio Console
will appear blank if the PCI-424 card is not
communicating with your audio interface. When
the audio interface is communicating with the
PCI-424 card you should also see the Clock,
Source, and Bounce LEDs glowing, or just the
Meter led glowing solid, not blinking.
To establish communication set the clock source to
internal and hit refresh. Try restarting the
computer if refresh doesn't regain communication.
Make sure the AudioWire is plugged in properly. If
you still can not regain communication, try one of
the other AudioWire connections on the PCI-424
card and then hitting refresh. Try reseating the
PCI-424 card in the computer or even try another
PCI slot. If you still have trouble you should contact
MOTU Technical Support for further assistance.
Stand alone conversion with the 2408mk3
With the computer off you can configure the
2408mk3 as a stand alone converter. Here is an
example for use with and ADAT device on Bank A.
Set the Source Row to ADAT GRP A Set the Clock
Row to SRC and it should lock to the sample rate of
the source. Set the Bounce Row to 1-2 >1 -2.
