Does this transmit over standard phono cable or need a special type?

Only if you belive the exotic cable salesmen! Any normal phono lead
should be fine, the quality of the cable for digital can be lower
even than for analogue.

Thanks - I've been putting standard phono in (2 for stereo and one for
video), so I only need one now for digital audio for my HTPC setup.

Strictly speaking, the cable should have a 75 Ohm characteristic impedance,
and many phono leads intended for analog interconnects won't have this
impedance. That said, provided the cable is short (metre or so) this is
unlikely to give a problem.

For peace of mind, though, I tend to recommend using a length of 75 Ohm
co-ax of one of the types usually sold for TV and VHF antenna leads. Of
course, not all such leads *will* be 75 Ohm at frequencies below a MHz..
;- So this comes back to "probably doesn't matter much" in most domestic
situations.

Slainte,

Jim
