The DI/O contains tube circuitry that can be used to warm-up digital
recordings. The amount of tube warmth is increased by turning the
DI/O's Tube Warmth knob clockwise. This control lets you increase
the amount of tube drive without increasing the DI/O's output level.
You can add warmth to any sound without having to readjust the levels
going through the DI/O.
completely and simply use the DI/O for its high-quality analog to digital
converters, turn the Tube Warmth control fully counter-clockwise to the
Clean position.
OTHER APPLICATIONS:
USING BOTH DIGITAL INS AND OUTS
The DI/O is an excellent tool for warming-up audio and then converting
it to high-quality digital audio. It is also an excellent tool for warming-
up audio that's already in the digital domain, such as from the output of
a soundcard or digital mixer. The DI/O can both accept and return
sound in the digital domain, thus making it simple to insert into your
existing system. For example, when mastering a mix to DAT, insert
the DI/O between your soundcard's S/PDIF Output and the DAT's
S/PDIF Input. Adjust the DI/O's Sample Rate to External. Use the
DI/O's Tube Warmth control to enhance your digital mixes and help
TO IMPROVE MONITORING SOURCES
Another great use of the DI/O is for monitoring the output of DAT
decks, digital workstations, and digital mixers. In most cases, the DI/O
offers superior performance to the on-board converters of your other
gear, which adds more life to digital, pre-mastered recordings. For
example, connect your DAT deck's S/PDIF Output to the DI/O's
S/PDIF In and send the DI/O's 1/4" Outputs to the 2-track (Monitor)
returns on your mixing board.
