AESx4
Distribution Amplifier
Description
The AESx4 is used to distribute AES3 (2-channel digital audio)
or AES11 (digital audio clock) between equipment using stan-
dard 3-pin XLR connectors. A switch on the front panel allows
you to select between a word clock and an AES input. When
the AES input is selected, either AES3 or AES11 can be buff-
ered then distributed to the outputs. When the WORD CLOCK
input is selected only, AES11 is generated based on the sample
rate of the word clock.
Switches
The AESx4 has one switch placed on the front panel that
selects either the WORD CLOCK or AES input.
LEDS
SIGNAL PRESENT: In AES mode, the signal present detector
drives an LED when there is activity on the AES input. In word
clock mode, the signal present detector is driven only when the
WORD CLOCK input is valid.
POWER LED indicates AC power is present.
Connectors
WORD CLOCK Input: Is a coaxial BNC connector with nominal
input impedance of 75 Ohms. Internal termination is provided
with a jumper.
AES Input: Is a 3-pin XLR connector with nominal input imped-
ance of 110 Ohms. Internal termination is provided, as per the
AES3 spec. The data can be either AES3 or AES11 (AES3 with
no audio data).
POWER: Supplied by external Lucid PS-3, PS-3E, or PS-3J.
AES Outputs: Are 3-pin XLR connectors with nominal imped-
ance of 110 Ohms.
Jumper Settings
·J1 is used to control the AES input pin 1 ground. The default
setting connects pin 1 of the connector straight to chassis
ground. The other position BYPASS has a capacitor between
pin 1 and chassis ground.
·J4 with positions HIGH or LOW determines the WORD CLOCK
input range. The HIGH range (default) accepts word clock fre-
quencies between 44.1 kHz to 96 kHz whereas the LOW range
accepts word clock frequencies between 32 kHz to 48 kHz.
·J6 sets the WORD CLOCK input to either TERMINATED or
OPEN (default). If the jumper is set to TERMINATED, the
driver's source impedance should be 75 Ohms to match the
AESx4's BNC input impedance.
