BNC Penetration Panel Adaptor Cables Accessory
Allows "differential pass-through" of the headphone signal coming from the transformer box when used with grounded penetration panels. Converts the normal "single BNC per channel" connections to "two BNCs per channel" (thus stereo requires 4 BNC positions on each side of the panel). This optional configuration allows the user to maintain the balanced drive signal from the transformer. While this accessory is not usually needed, it may be helpful in certain situations when tracking down RF leakage or artifacts peculiar to a particular installation.
