Manual EQ
In manual adjust mode a card-edge mounted, multi-turn potentiometer
manual EQ adjust is used for adjusting equalization. The Lock and
Confidence flag warnings on the card-edge mounted LED indicator can
be used to determine the amount of EQ required without external test
equipment. If the confidence flag error light is on, more EQ is needed.
To increase the amount of EQ, use a screwdriver to turn the manual EQ
adjustment potentiometer counter-clockwise until the Confidence LED
indicator turns off and the Lock LED indicator turns green.
Automatic EQ
In automatic adjust mode, the AES6800
+
automatically sets the amount
of cable EQ needed to improve signal quality in case of signal
degradation over extended cable lengths.
The EQ is designed for use with up to 2,000 ft (609 m) of Belden 8281
coaxial cable or equivalent, or up to 1,000 ft (304 m) of Belden 8451
twisted pair cable or equivalent.
AES or Bypass Mode
AES Mode
AES mode is used to allow the distribution amplifier to automatically
receive and decode audio data according to AES3 interface standards. It
also allows the DA to decode the AES data stream for any error
information.
Bypass Mode
Bypass mode is used to allow the distribution amplifier to pass
non-AES or non-biphase encoded signals of frequency less than 30
MHz at 50% duty cycle.
Note
The factory default
configurations for J1 is in the
“AUTO” position.
Note
The factory default
configuration is for AES mode.
