Need dbx mpa 150 manual
dbx MPA-150 is a mono amp. It will take L&R speaker inputs from your receiver, filter out the bass and pass the mids and highs to the direct out terminals for your normal speakers. It then combines the bass signals to one channel, amplifies it, and sends it to the L&R subwolfer out terminals, (marked single speaker L+ and R-). If you have 2 subs connected, the L&R are wired in series internally, L- and R+ are jumpered. Thus 2x 4ohm speakers become 1x 8 ohm speaker, and the impedance switch should be set accordingly. The line level mode works quite the same way but subwolfer output only.
