ART Pro Audio DIO - A/D Converter - Manual (Page 3)

INSTALLATION
The DI/O may be used in a wide variety of applications and
environments. Self-contained in an all-steel enclosure, the DI/O is
designed for continuous professional use. Because the unit is compact
and lightweight, mounting location is not critical. However, for greater
reliability we recommend that you not place the DI/O on top of power
amps or other sources of heat. The tube circuitry needs about a minute
to “warm up” from a cold power up.
AC POWER HOOKUP
The DI/O has an external power supply designed to operate at 115
VAC @ 50 to 60 Hz. Units manufactured for use outside the United
States of America have been modified to comply with the required
electrical specifications. Only use the adapter that came with the
DI/O. If the adapter becomes lost or damaged; contact ART Customer
Service for replacement. If you need to purchase one locally, just make
sure that you specify 9 Volt AC output (not DC), at 800 ma.
AUDIO CONNECTIONS
Audio connections to and from the DI/O are unbalanced ¼” (Tip = Hot
(+), Sleeve = Ground). We recommend that you turn down the INPUT
GAIN control whenever changing connections to the inputs.
SAFETY PRECAUTIONS
Warning: To avoid the risk of shock or fire, do not expose this unit to
moisture. Refer all servicing to qualified personnel. Do not remove the
metal cover; there are no user-serviceable parts inside. You should
only use the power adapter that came with this unit or one obtained
from ART’s Customer Service Department.
