Multiple inputs, on different outputs.

Best way to be able to hook up a turntable, and a DAC(For PC audio) to both a headphone amp and speaker amp? (Not to be used at the same time) My current idea on how to do this is using the A30's pre-amp line out but could that possibly cause damage to the speakers/amp?

I see from Topping's site

With both RCA input and output on the back panel, the A30 can also work as a preamplifier with hardware volume control that benefits from powerful yet precise op-amps (OPA1611, OPA2134). The hardware volume control is handled by ALPS potentiometer.

Would it be safe, just to run it, and keep the volume nob at zero?

With it only being a preamp and the volume nob being a potentiometer? I'd assume no damage would occur?

No reason why it won't work just fine.
