500 SERIES
LINK ELECTRONICS, INC.
AES/EBU DIGITAL AUDIO TO ANALOG
MODEL LEI-547
FEATURES
18 BIT DAC
AES-EBU Audio DA
Stand-alone
Four Outputs AES3-ID
Two Stereo Analog Outputs
Error Detection
Transformer Coupled Digital I/O
FP Select BNC/Terminal Input
Monitoring Distribution
The LEI-547 accepts either AES3-1992 or AES3-
ID inputs and provides a total of four outputs of
digitalaudiotoAES3-IDspecifications.Inaddition,
it provides two sets of balanced low impedance
analogoutputs.Transformercoupleddigital inputs
and outputs are standard to eliminate the
possibilityofgroundloops. Captivescrewterminal
blocksareused for the AES3-1992whileAES3-ID
use BNC connectors.
A front panel switch selects between BNC or
screw terminal, (AES3-ID, AES3-1992). Sample
rate LED’sshowthreerates,48KHz,44.1KHzand
32KHz. An error detection LED indicates any
errorson theincomingsignal. AnACpowerswitch
on the front panel allows the user to turn the unit
on or off at will. The fuse is on the front panel for
easy access..
The analog conversion is accomplished using a 1-
BIT Delta-Sigma converter with 18-BIT resolution.
The output cells employ a unique cross-coupled
design for precise amplitude and phase matching.
The digital signal path uses state-of-the-art
integrated circuits. The data is re-sliced and re-
clocked for jitter attenuation. Sample rate is
automaticallydetectedandindicatedbyfrontpanel
LEDs. Data errors are also detected and reported
by a red LED on the front panel.
The 500 series is housed in the same case as the
well accepted 700 series. A black front panel
distinguishesbetweenthetwoseries.Three500or
700 series can be mounted in the PRT-700 rack
tray.
