what does this mean?


Hi all-

I'm setting up a new compact system with a Schiit Freya Plus preamp and the Orchard Audio Class D Monoblocks that have recently gotten so much nice attention.  (Speakers will be the Harbeth P3esr).  One thing confuses me, however.  In his Absolute Sound review, Dick Olsher writes:

"The proprietary circuit topology features a DC coupled, balanced modulator stage, and a full-bridge differential power stage (both speaker terminals are 'hot' when the amplifier is on.)"

What does it mean that the speaker terminals are "hot" when the amplifier is on?  And does it imply any extra safety precautions on my part?

If anyone has any experience with the Orchard mono blocks, I'd love to know that as well!

Thanks!

Margot

My Pass Xa-25 amp is also DC coupled. Pass warns to unplug the amp when attaching speaker cables. Shorting either side to ground (case) could cause unspecified damage.
