Edirol FA 66 firewire

It's likely that the FireWire bus isn't meeting the power needs of your card. Just use the external supply since there isn't too much you can do.

Is the noise a constant hum? If it is such a noise, I suspect a faulty or poor performing power supply. Check the power supply that powers Edirol sound card for any improper ground. Another custom made power supply which is properly regulated (voltage) and at a higher ampere rate would be an idea to consider. I think your main issue is grounding because you say the case become worse when the MacBook PSU is not there. Because, you are loosing a ground path when you remove the PSU. Then it solely depends on the Edirol ground path. If that path not a good source of ground, there lies your problem.

this error is usually shown when starting up an audio app while there's a different one already running... before starting up your AL8, check if no other audio programs are running (players such as WMP, Winamp, VLC, editors like Wavelab, ......)

Possibly, your adapter of small to big is not a stereo adapter. Seems like a mono adapter.

its probably a ground loop (i think thats what it's called)
sometimes if a number of sound devices like monitors/computer/soundcard are connected
with the same ground, this problem occurs.

so maybe try use a ground-less electricity wire on the mpc, or the laptop. or both.
good luck.

1.i gained info about the mains supply data (9 volts 2 a, minus pole in the center pole of the plug) which is a quite exotic supply in comparison to standard devices with 12 volts an plus pole in the center pole ...
the fa 66 didn't work , when connected by 4 to 4 or 4 to 6 firewire cable .
my laptop only has a small 4 pole socket.
therefore i suppose that through this 4-pole socket and cable there was no current lead through.

after additionally connecting the fa-66 with mains supply AND 4 to 6 (fa 66 side) cable ... it finally worked.
the manufacturer should print all relevant data directly to the fa 66 device near by the socket und also print "FA-66" onto the supply ... because i own lots of alike-looking supplys and it's a drag to find out which ist good for what...
;-)

u're probably trying to connect it with a 4 to 6 pins firewire cable to your laptop right?
if so, the laptop firewire connection is usually the small type (4 pins). this kind
of connection does not give Power to the firewire device.
u can buy a pcmcia card with 6pin firewire connections and usa a 6 to 6 firewire cable
and that will work. i hope. :)

Judging from the wiring diagram on the cover, the headphones are connected to the same output lines as 1 & 2. When you increase or lower the monitors. So do the headsets. The only way to get around it is to find a pair of headsets with at volume control into the wiring of the headsets or plug the monitors into outputs 3 & 4.


Here is the book I saw

I bought the FA-66 because I use Cakewalk Sonar and they sell this interface on the Cakewalk site with thier name on it. I've had nothing but problems with this unit as described above. I've tried it on two different computer and it does not work on either. I also use an RME Fireface 800 on both these machines, same set up and it works flawlessly. Drop the Edirol/Roland FA-66 and try something else like an RME card or something. That would be my suggestion. It's a shame Cakewalk promots this piece of garbage. I've tried Edirol/Roland technical support and the guy just kept saying the sound card works fine, like it was just my problem.
