ATI Audio UADC-1 - Manual

Audio Technologies Inc. 856-719-9900 [email protected] www. audio.com
Product Description
The ATI UADC-1 Utility Analog-Digital Converter / Switch provides professional quality 24-bit A-to-D
conversion, along with AES audio path insertion and interruption functions. The UADC-1 may be used as a
standalone high quality A/D converter or to insert stereo analog inputs into an AES stream via remote control,
making it a perfect companion for analog EAS encoders/decoders.
The UADC-1 is equipped for failsafe operation with relay bypass in case power is lost. The A/D converter is
shipped to provide broadcast standard 44.1 kHz sample rates, with 32 kHz or 48 kHz sampling selectable via
internal jumpers. XLR analog audio inputs are balanced when shipped from the factory, but may be switched
to unbalanced, single ended inputs via internal jumpers. (See INSTALLATION Section for internal jumper
settings.)
The front panel includes left and right analog input trimmers, Audio Present and Clipping LEDs for each
analog input, and status LEDs to indicate Remote Active, Analog or Digital Input Selected and Power.
The rear panel includes XLR connectors for balanced left and right analog audio inputs, AES input and AES
output. 3-pin connectors are provided for Unbalanced analog stereo input and remote control inputs. Power is
supplied via a 110 VAC outboard power supply (included), which supplies 24 VDC to the unit.
Installation
Please examine your UADC-1 Utility Analog-Digital Converter / Switch carefully for any damage that may have
occurred during shipping. If damage is noted, please notify the shipper immediately and retain the packaging
for inspection. The package contains the UADC-1 unit, one 24 VDC / 600 mA power supply and this manual.
Please read this manual thoroughly before you install and operate the unit. Do not use this product in any
application where a life threatening condition could result due to its failure.
Use care when installing the UADC-1 in high RF environments. Shielded cable is suggested for all audio
connections. All shields should be tied to the “G” or ground connector pins. It is recommended that all cables
connected to the UADC-1 be looped through ferrite cores to suppress RF. Power line surge protection with RF
filtering is also suggested for the external power supply.
To gain access to the UADC-1 unit’s internal configuration jumpers, disconnect power and remove the six
Philips screws that secure the cover. When configuration is completed, reinstall the cover with the six screws
and re-connect the power.
The ATI UADC-1 Utility Analog-Digital Converter / Switch can be rack mounted using the optional 21075-501
19” Rack Mount Shelf Assembly and 21098-501 ½ RU Filler Panel.
