There's no need to haze a MOT who's just here to tell people how to update existing products for free. I don't know that anyone here has one of those amps, but there's no harm in this information, I think.
Obviously the manual doesn't say that, life does. Anyway, I stick by my recommendation, which is that you do what the manual suggests, and go TRS->rca. Apparently, marc doesn't agree.
there's no tone in text. You accused me of "hearing a couple of inches of cable". You are a big one for hinting that someone is wrong, and then waiting for an excuse to pounce. So stuff it, prick.
