ANALOG AUDIO TO DIGITAL AUDIO AES/EBU
DIGIFLEX 1660
MADE IN THE USA
1000 SERIES DIGIFLEX
Fault LED Analog to AES\EBU Transformer Coupled Digital I/O External Reference Input BNC or Terminal Connections
The DigiFlex 1660 accepts one analog stereo input and provides one output of digital audio to AES3­1992 or AES3-ID specification. Up to eleven 1660's may be mounted in a 2RU space with LINK's DigiFlex frame. Transformer coupled digital inputs and outputs are standard to eliminate the possibility of ground loops.
The 1660 companion rear cell, model 1020, allows the user to select terminal or BNC connec­tors for digital output. Captive screw terminal blocks are used for the balanced analog input. The DigiFlex mounting frame with rear cell selection provides for future growth into the digital or analog video/audio system requirements.
1000 - Single Power Supply, Holds 11 Modules
Mounting Frame Options
1000/2 - Dual Power Supply, Holds 10 Modules 7200 - Mounting Frame, Holds 1 Module
Selectable Full Scale +10dBu to +28dBu 20/24 Bit Conversion, Selectable 48 Khz Internal Reference Automatic External Reference Detection External Reference Presence LED Control of Channel Status Bits
The digital signal path uses state-of-the-art inte­grated circuits. Reference sample rate is automati­cally detected and indicated by front panel LEDs. External reference errors are also detected and reported by red LEDs on both the front and rear panels. A "Frame Fault" output can also be en­abled for centralized error reporting.
The digital conversion is accomplished using a 2­bit Delta-Sigma converter with 24-bit resolution. Designed with the professional in mind, the DigiFlex 1660 will provide years of error free performance. Backed by LINK's standard 10-year warranty, the 1660 combines high-performance, reliability and economy.
