PMA 2100

came by a PMA 2100, a healthy chunk of two channel amplifier, I am unsure of specs, ? rms watts x two channel into ? min Ω, bridged output min Ω. RCA input voltage?. A source for the manual would be welcome. I have had good results with Carver car amps in the past and would like to feed and tend this one according to its needs, they don't come by too often.
P.S. Many thanks for all the knowledge amd info posted to the site.
