RA280 high level connection to subwoofer

Hi

Does anyone know if I can connect my subwoofer via high level connection instead of the subwoofer output (RCA). THe amp is RA280

@Audioresearch1074

RA280 amplifier, however, does not have a dedicated subwoofer output (RCA pre-out), so high-level input is a good alternative if your subwoofer has high-level inputs (e.g., binding posts or a Speakon connector).

Sorry i mean RA280 not RS

@Audioresearch1074

I meant RA280 too.
