Topic: UFX+ / Lexicon PCM 81

Want to integrate a Lexicon PCM 81 into my UFX+ based setup, preferred via AES.
Do you know by heart whether the Lexicon PCM 81 can be clock slave via AES ?

Desired setup: UFX+ as clock master, PCM81 as clock slave

UFX+------ AES OUT --------> PCM 81 (as reverb unit)
UFX+--<-- AES IN ------------  PCM 81
UFX+------ ADAT1 OUT -------> ADI-2 Pro ----> Monitoring (Main Out) / Phones
UFX+------ ADAT2 OUT -------> ADI-2 Pro ----> HiFi (Main Out B)

Alternatively: connect through analog.

BTW .. does somebody sell a PCM81 in very good condition?
DUAL FX card also welcome. Please contact me by mail in regards to this, many thanks.

Hello, Ramses!!
How are you?

I haven't used one, but I found this in the Lexicon's manual:

The PCM 81 will not lock onto an incoming digital signal.

Check the cables that you are using. DO NOT USE ANALOG AUDIO
CABLE TO CONNECT DIGITAL AUDIO.

Digital AES/ AES(XLR):
  Check connection to XLR and make sure that
  the Digital Lvl control at Control mode 0.2 is
  set to 100%. Make sure that WordClock
  (Control mode 0.0) is set to Ext: XLR 48 or 44.

It 's in the Troubleshooting section, Chapter 6-3, page 164(Mozilla viewer, because the manual doesn't have page numbers)
Link to manual:    https://lexiconpro.com/en/product_docum … de_rev2pdf

So, I guess it can be Clock Slave!

Hi MetalHK, thanks for checking. If necessary, it would also work analog for me, as it is now.
