box as high voltage equipment (75+ volt) unless an
approved barrier separates high from low voltage
equipment.
4. Speaker wire can be solid or stranded. Suggested
minimum wire size is 16 gauge and 12-14 gauge for
runs longer than 30' (10m).
5. Wire both left and right speaker outputs from the
amplifier, receiver or interface to the VC75 inputs.
