Monitoring 5.1 from Kona 3
on Jun 11, 2007 at 3:15:53 pm

We are just in the process of nailing down the pipeline for a feature (shot on 35mm telecine to HDCAM SR for editing and DI), However client requires 5.1 sound monitoring for the final edit. Currently we have KRK V6 (Series 2) speakers for monitoring Stero.
We did look into the TASCAM 1884 again some concerns with audio sync issues. Maybe someone is using this and some feedback would be much appreciated.

The Q's
1: What converters are some of you guys using for AES to Analog
2: Some feedback on speaker set-up ( since we have the KRK V6 , we thought of extending this with 3 KRK V8 and V12S for sub)

SYS INFO: 8-Core Intel, 9GB Ram, X1900XT, KONA 3.

Thanking everyone in advance

Are you planning to monitor from the Kona card? The solution to convert to analog from AES/EBU might cost you more than just purchasing a separate audio interface. You would also lack hardware control of speaker volume. I suggest the Presonus Firestudio with the optional MSR remote. This would give you analog outputs as well as hardware control over your speaker volume, including individual mute and solo. If you are set on converting from the Kona outputs, try the RME ADI192DD. Both will work, but plan on something like the SPL 2381 to control volume if you get the converter.

The plan was to monitor direct from kona 3 card, so that there is no sync issues. As I mention the TASCAM 1884 does have the ability to monitor 5.1 but the sound sync is an issue, since we monitoring the video from the kona with the Panasonic BT-LH1700W. Unless there is a way that i can use the frameoffset in the FCP2 (system setting), doing this is a bit scary.

Again thank you for the advice, we will look into some of the suggeations.

Depending on how concerned with quality and how much you're willing to invest, look at the Dolby DP569 and DP562 which would allow you to hear the actual Dolby Digital mix which may not sound the same as the direct discrete mix. I haven't tried it yet, but you could probably connect a consumer decoder to the optical port on the Mac and monitor that way.

Oh boy, I wasn't thinking! You can't monitor Dolby Digital with a decoder! It would have to be mixed and software-encoded first before you could (and that's a pain). The only way is with at least a multi-channel audio card sending discrete audio out, but the best way is with the DP569 & DP562 (about $8000 total) since you can actually monitor the encoded DD instead of discrete with which the mix may vary from the DD mix.

I am wondering this as well.

I have the Kona and Tascam 1884.

I also own the Aja IO. I have debalted selling the IO so many times but it keeps having more uses. You can take the AES/EBU from the Kona into the IO and ADAT out of the IO into the FW1884. I used to do this with stereo all the time.

I now have to try this with 5.1 mixing.

I dont think I would do 5.1 in FCP however, but in Soundtrack pro 2.

So much to try. Not sure when I will have the time since I am not required
to deliver any surround mixes. Also I believe you need a Dolby E encoder to
lay 5.1 onto tape.

I would just rather have a sound house deal with all this.

How many jobs can I be expected to do?

I guess another "dirty" way of doing this could be just using the optical out of my 8-Core and use my harman / kardon AVR 445 Receiver.
I did some test setting up some soround sounds in Sound Track pro and monitoring using the optical out, seems to work fine (again I'm not a sound guy). I supose i should just do a mix down and import this to fcp 2 and see what happen??

That's true. DP562, DP569, DP571, DP572, LM100...these things get expensive, and are best left to audio post facilities when doing 5.1 for broadcast (that's a lot to tackle).

I guess another "dirty" way of doing this could be just using the optical out of my 8-Core and use my harman / kardon AVR 445 Receiver.

Yeah, I slipped up and mentioned that earlier, but you cannot output 5.1 from the optical out unless you encode it first. There is no way (currently) to encode on-the-fly while mixing while outputting an AC-3 bitstream. You have to either mix discrete or through a DP569/DP562 combination.

**EDIT** Sorry, I've been typing DP562 instead of DP564 for the decoder.

oh boy! looked into the decoders and additional hardware required, it certainly is expensive. We are working with the audio guys to figure this out, possibly have the screening at the audio studio.
Again thanking everyone for the advice.

Oh boy,
You may be seriously overcomplicating things. You want to monitor, right? Are you monitoring an encoded file? If not, then monitoring a
discrete 6 channel output IS the way to go. I work with lots of surround and we usually do a screening with discrete channels. If you need to use an encoded source do a render from compressor with dolby encoded and use the optical output of the Mac to your surround reciever. As far as sync goes I have never had issues.
