LINK ELECTRONICS, INC.
ANALOG AUDIO TO DIGITAL AUDIO AES/EBU
DIGIFLEX 1660
FEATURES
Fault LED
Analog to AES\EBU
Transformer Coupled Digital I/O
External Reference Input
BNC or Terminal Connections
TheDigiFlex1660acceptsoneanalogstereoinput
and provides one output of digital audio to AES3-
1992 or AES3-ID specification. Up to eleven
1660's may be mounted in a 2RU space with
LINK'sDigiFlexframe.Transformercoupleddigital
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 connec-
tors for digital output. Captive screw terminal

video/audio system requirements.
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 inte-
gratedcircuits.Referencesamplerateisautomati-
cally 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 en-
abled for centralized error reporting.
The digital conversion is accomplished using a 2-
bit Delta-Sigma converter with 24-bit resolution.
Designed with the professional in mind, the
DigiFlex 1660 will provide years of error free
performance. BackedbyLINK'sstandard10-year
warranty, the 1660 combines high-performance,
reliability and economy.
