USING BOTH ANALOG INS AND OUTS
The DI/O also can be used on completely analog signal paths. For
example, during a live performance, the DI/O can sweeten up the
harsh sound of some keyboards and synthesizers. Simply use the 1/4”
Input and Output jacks to insert the DI/O between your keyboards and
amplifiers. Use a single RCA cable to loop the DI/O’s S/PDIF In to its
S/PDIF Out. Set the DI/O’s Sample Rate control to 96kHz (for
transparent digital audio pass-through) and adjust the Input Gain and
Tube Warmth controls as desired. The Input Gain control can be raised
to further optimize the output signal level if going over long cable runs
(to the amps, mixing board, etc.).
SPECIAL EFFECTS
For industrial, metal, or just “flavor” textures, experiment with the DI/O.
Overdriving the tube can add interesting textures when used on vocals
and other instruments, especially if you are going for analog tape
saturation effects. When using both analog Ins and Outs (see above)
it is possible to cascade the left channel into the right channel to obtain
doubly overdriven effects. Simply plug your source into the DI/O’s Left
1/4” Input, connect the DI/O’s Left 1/4” Output to its Right Input, and
send the Right Output to your mixing board, analog recorder, etc. Turn
up the Input Gain and Tube Warmth controls until you achieve the
desired effect. No harm will come to the DI/O with this type of
experimentation, though you may need to lower the signal level going
into the next piece of equipment. Be sure to have monitoring levels
turned DOWN before “testing” the sound.
TUBE REPLACEMENT
The Tube in your DI/O should last for many years. They are hand-
sorted for optimal performance in our specific circuits. In the event that
you need to replace them, A R T suggests that you do so with tubes
available from A R T. These are matched to the DI/O and will yield
consistent sonic results. You can replace the tubes with other brands,
however A R T has no responsibility for the resulting sound quality.
