Interconnect cable checklist:
Connect the inputs to a suitable source, e.g. a head unit with good quality RCA cables.
Control checklist:
Refer to the section “Settings for Best Performance”
Use at least #12 gauge speaker wiring. The amps have dual speaker terminals,
simplifying the hookup of multiple speakers. These amps are mono, 1 channel, amplifiers
Minimum final loudspeaker impedance:
which have multiple positive and negative connections for ease of wiring. The 2 positives
-OA500.1 = 2-Ohms
are the same internally and the 2 negatives are the same internally.
-OA750.1 & OA1000.1 = 1-Ohm
