Hi,
I have a KRK ERGO that I intended to use as a Firewire audio interface as well (supposed to offer this feature) but on Mac it looks like Apple Leopard Firewire Driver has issues and I can't get the sound to go from my MAC to my monitors

Unles the issue is resolved I have two options
1) use the digital output from the Mac Pro (Toslink) to maybe go into the Digital input in the KRK ERGO (SPDIF). And viceversa I guess to have digital I/O in the system.
In this case I need to find a cable that goes from Toslink to SPDIF I think

2) send the ERGO back and go for alternative solution. IN this case what options do I have for an internal audio card for latest Mac Pro that will give me Digital I/O, Analogue I/O, hopefully zero latency?

Thank you for your help/suggestions

Interesting - I didn't realize KRK were touting the ERGO as a firewire interface, but I've just checked their website and it does indeed say the firewire spec is capable of 4 in 6 out operation (in the small print of the tech specs)

Basically though, it's main selling point is as a 1) room correction device and 2) monitor switcher. If you want to keep the room correction you'll need to hang onto the ERGO and and buy a separate audio interface as well

If you're not bothered about the room correction, the ERGO seems a strange purchase in the first place - just out of interest, have you been able to measure your room using the mic? Or can your Mac not see the mic inputs at all? How have you set it up so far? If you can't get your Mac to even see the device for the purposes of room calibration I would suggest contacting KRK for some tech support

While you're at it I would ask them if it's really supposed to work as an audio interface - because they don't seem to be selling that feature very hard if it is

To answer your questions about workarounds:

1) There's not much point using the Mac's built-in digital output (TOSLINK) - to do anything with music and recording you need a decent low-latency audio interface

2)There are loads of options - search this forum for some favourites but it depends a lot on budget, how many ins and outs you need, etc etc

Cheers

Hi,
back from holiday sorry for the delay.

Yes the calibration stage was fine because the ERGO emits the sound waves it requires to calibrate its filters. So the connection between ERGO and Monitors and ERGO and included MIC are fine. You don't need audio coming off the MAC for calibrating the ERGO. You don't need audio going through the external MIC into the MAC to calibrate the ERGO.

Yes I bought the ERGO because I wanted to use it for all its features, room correction, speaker/Sub switcher, volume control, firewire I/O.

I tried a few different things with help from some KRK guy. But the problem is still there. When outputtinbg audio off Logic or even playing an mp3 song through an MAC mp3 player if the audio goes through the ERGO is comes out liek ecohed noise. The only strange improvement so far was that now I can hear the first 10 seconds of my track just fine then the bad noise kicks in.
