McCormack DNA-1 Rev A question

Unsound- I guess we all have different ideas of the semantics involved. If you go thru the various threads on this, you will see lots of confusion and if I contributed to it, I apologize. One way to perhaps differentiate is to call them internal or external bi-wiring. Internal, in my mind, is a single + & - at the amp end and separate + & - at the speaker end, one set for the woofer and one set for the mid/tweeter. External bi-wiring is two completely separate runs from the amp. Now they can be on the same amp binding posts, but that can be ergonomically difficult. Or each of the two separate sets of cables for each channel can originate from a separate set of binding posts which is easier to implement for the consumer and less likely to result in shorting across the amp's binding posts.

Swampwalker, I guess your right re: different ideas of the semantics involved. My idea of internal bi-wiring is the appearance of one cable with 2 + and 2 - on both ends for each channel, and external bi-wiring is two separate runs with 1 + and 1 - at both of ends of both separate runs for each channel. And shotgun would be 2 barrels from one trigger. :-)

Unsound- WRT the OP's question, regardless of our own interpretation of the semantics the answer about the 2 binding posts is to facilitate bi-wiring. More importantly, it is NOT to drive to sets of stereo speakers.

Agreed.

I am learning something new all the time in this hobby. I didn't think of biwiring since I've been using Jumpers all along. Thanks for everyone's responses.
