DC-DC converter in the normal primitive sense is a Voltage Regulation
IC. A common one is the LC7805 which is a 5 volt regulator. It can
handle up to 35 volts input and still hold the output at 5 volts.
Supply of excess voltage does mean more heat given off by the chip.
What is impossible to predict is how well that IC is heat sinked to a
chunk of metal in your device. This is a bit simplified description
because with digital stuff often a -5 volts is needed as well which is
a LC7905.
In recent years some manufacturers are getting smart and using this as
an advertising plus. The SD722 recorder markets their recorder as
being able to accept 10 to 18 volts. They likely are using a LC7805
and allowed a 2X safty for voltage spikes and the like. This makes
further sense considering the recorder powers down at about 6 volts.
Other manufacturers like RME are allowing either polarity with either
DC or AC voltages to be supplied to their equipment. This just takes a
couple more diodes to make a full wave rectifier with input isolation
and a bit more filtering to work.
Probably a bit more than you wanted to read. My answer is vague but
boils down to try it at your own risk and if it gets hot then stop that.
