500 SERIES
LINK ELECTRONICS, INC.
AES/EBU DIGITAL AUDIO DA
MODEL LEI-540
FEATURES
AES-EBU Audio DA
Stand-alone
Six Outputs AES3-ID
Two Outputs AES3-1992
Transformer Coupled
Front Panel Select BNC/Terminal Input
The LEI-540 accepts either AES3-1992 or AES3-
ID inputs and provides a total of eight outputs of
digital audio: six to AES3-ID specifications, two to
AES3-1992 specifications. Transformer coupled
inputs and outputs are standard to eliminate the
possibilityofgroundloops. Captivescrewterminal
blocks are used for the AES3-1992 input/outputs
while BNC’s are used for the AES3-ID
connections.
A front panel switch selects between BNC and
screw terminal, (AES3-ID, AES3-1992). Sample
rate LED’sshowthreerates,48KHz,44.1KHzand
32KHz. An error detection LED indicates any
errorsontheincoming signal. An AC power switch
on the front panel allows the user to turn the unit
on or off at will. No need to go behind the rack to
check the fuse; the fuse is on the front panel.
Many features are found in the LEI-540 for
professional use.
The digital signal path uses state-of-the-art
integrated circuits. The data is re-sliced and re-
clocked for jitter attenuation. Sample rates are
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.
Designed with the professional in mind, the LEI-
540 will provide years of error free performance.
Backed by LINK's standard 10-year warranty, the
LEI-540 combines high-performance and
economy.
