API 500-VPR
Not much is documented about the API 500-VPR. What the record shows comes from a single 2009 equipment directory listing in Mix Magazine (December 2009, p.30). It calls the 500-VPR a 10-space vertical rackmount chassis for API's 500-series modules, with an internal power supply and a list price of $949. The same listing treats it as the rackmount counterpart to the more portable API 500-6B Lunchbox (six spaces, $499).
Past that directory entry, almost nothing is recorded about the 500-VPR. There are no service manuals, no production timeline, no dimensions or weight, and no details on connectivity. It appears to have been a plain utility piece: a powered rack frame to hold API's interchangeable preamp, EQ, and compressor modules in a standard studio rack instead of on a desktop. How long it stayed in production, or how many units were made, is unknown.
