Proceed AVP2

I recently purchased a preamp/processor which was advertised as a proceed AVP to mate with the Mark Levinson 27. I like the result but am a bit confused because, for one reason,  it came with two manuals, one for an AVP and the second for an AVP2.  Also, when looking for the serial number on the bottom placard it states AVP2. If it is the 2 that, of course, would be good news.  I googled images of the 2 and saw that some have AVP2 printed on the front panel; others simply state “audio video preamplifier” like mine. It was necessary to perform a factory reset to change the output from XLR to the RCA default output and used the AVP2 instructions to do this.  Is it possible that this is actually an early 2 or a factory upgrade of the AVP?  I’m pretty happy with it either way but would appreciate advice from someone with knowledge about this unit. Thanks.
