(Optional – Used to power GVDD from separate 12-V to 15-V power supply, for idle current measurement. JP1 must be
removed to use this connector. JP1 must be installed for normal operation.)
CAUTION
Both positive and negative speaker outputs are floating and may not be
connected to ground (e.g., through an oscilloscope).

This connector is a standard TOSLINK connector that connects the SPDIF digital audio input to the SPDIF
receiver on the HPL-MC012 PCB. This connector, or the SPDIF co-axial input, is used, but not both
connectors at the same time.
