Dual,dedicated AC circuits??? Electricians??

My recommendation is Armor Clad for Health Care Facilities (AC-HCF).

Reprinted from the link below: Aluminum Armor Clad for Healthcare Facilities (AC-HCF) is the best choice for Isolated Ground A/V systems. Like MC, it contains an additional grounding conductor, although with this type of cable it is permissible to use the metal jacket as the safety grounding conductor, as required with isolated ground installations. The biggest benefit is that the average proximity of the hot conductor and the neutral conductor with respect to the isolated equipment grounding conductor is nearly equal, virtually eliminating ground voltage induction (GVI), even on long runs.

You could use the red conductor as an isolated ground, but it should be marked with green tape in the circuit breaker box.

See Middle Atlantic’s page 12.

Optimized Power Distribution and Grounding for Audio

Shielded. Conduit is code around here. Just hook both circuits to the same "leg" in the box.

If no conduit, How about BX shielded cable?

I prefer galvanized steel armored MC cable 10AWG for, dedicated audio circuits. MC helps to reduce RFI, EMI, and electric fields, on the dedicated branch circuits, feeding your audio equipment. I have four true dedicated branch circuits, for audio. 😎

should wires be separated a certain distance? How far apart?

Yes. Mine are 4’’ apart!
