Mic Switch Operation
The MIC switch must be set to EXT for the built-in speaker to function, even if the
individual LEFT & RIGHT INPUT switches are set to LINE. This is to prevent feedback
from occurring between the built-in mic and the built-in speaker.
FireWire Power
Some PCI FireWire cards have been found to have a power connector on them that can
take power from a disk drive-style power connector. Such cards rely on that power
connector to make good voltage available to a device connected to their FireWire
connection.
If your PCI based FireWire card has a connector for a disk drive-type power plug, it must
be connected for proper FireWire voltage to be available to the HD-P2 via the FireWire
connection.
