Yamaha A-S2000 and REL-R305 High Output Hook-up


Is it safe to use Neutric Speakon Cable High Level output with Yamaha A-S2000’s “+” and “-“ speaker output terminals feeding REL Sub? The Users Manual doesn’t covers that subject, however I remember warning on my Ayre AX-7 back panel saying DO NOT use speaker “-“ terminals. Thanks.
