Software Upgrade for Proceed AVP-S?

Jason, the last released version of software was v3.32. To
identify the version you are running under menu there is a
heading called "about" if you are running 3.32 you will see:

BOOT CHECKSUM: 97f2
AVP ID: 06210211
DSP ID: 0374:6

As for multiple subs, I don't think any software addressed
that. You need to use a y-cable (adaptor) on the sub out
rca connector.

Thanx. I'm running v1.0, if you know where I can get later software, I'd be very grateful. I thought that in later versions of the software, the additional 2 pre-amp outputs could be tasked for multiple subwoofers. The manual mentions the potential, however, it never really describes the process of turning it on, so I assumed this was addressed in later software versions. In fact, even the OSD hints at that possiblility, by stating that you can have subwoofer set at None or One (leaving implied that there might have at some point be more than one!)

Jason, I stand corrected, I just the read manual (but don't
tell anyone). It does state: "Stereo Subs: you may also elect
to use stereo subwoofers, in which case the regular sub output
will handle left and Aux 1 will handles the right.".

As for the software, you wil need both the upgrade software as
well as the installer program (pc based) and a serial cable
with a RJ-11 to a DSUB9.

Good luck
