To sum up: Signal from PC (ASIO or other) --via USB--> to POD HD is digital Signal from Variax Guitar --via Variax Digital Interface--> to POD HD is digital Signal from POD HD --via L6 Link--> to Stage source #1 is digital. Signal from Stage source #1 --via L6 Link--> to Stage source #2 is digital. No D/A conversion should be necessary, except at the preamp stage of the speakers of course. Unfortunately, the POD HD doesn't transmit the signal coming from the PC via the L6 Link (this would imply to merge the USB audio signal to the POD signal). This is the problem.

Hello silverHead, thank you for your suggestion. Unfortunately, the cd/MP3 input is not transmitted by the PODHD500 via L6LINK (only on the PHONES, UNBALANCED and BALANCED outputs, as it said in the quick start guide). In fact, I expected that a sound track played by my PC via the USB interface of the PODHD500 would be transmitted via the L6LINK in addition to the guitar sound. But this is not the case. This is why I bought a good USB audio DAC as workaround, with the limitation explained before (music played on only one speaker when the PODHD500 is switched ON).

I encountered the same problem than Jbstudtm. I bought two L2M + a good USB audio DAC. L2M #1 is connected to L2M #2 via a L6 link. My POD HD500 is connected to L2M #1 via a L6 link. The USB audio DAC is connected to the R/L audio inputs of the L2M #1. When the POD HD500 is switched ON, the guitar can be heard on the two speakers, but the USB DAC is played on the L2M #1 only. I would expect to be able to play guitar on a backtrack in stereo without having to change anything in the connections (!). This important limitation is not documented anywhere (see the Audio Signal Flow in the L2M specifications). I paid more than 1200€ to get a system that is finally not so versatile.. My main motivation was to play with my Variax guitar on a system where the conversion Digital to Analog is made in the L2M preamplifier only. Playing on a backtrack is a normal use case. Why this limitation has been introduced?
