•
J4 is the High Pass Filter jumper. With pins 1 and 2 connected, the filter is disabled.
With pins 2 and 3 connected, (factory default) the filter is enabled.
•
To change the AES reference input from terminating to bridging, remove jumper J5 .
•
Jumpers J12 , J13 , J14 , and J15 affect phantom power:
~ Jumpers J12 and J13 affect the left mic input. Jumpers J14 and J15 affect the right
mic input.
~ With pins 2-3 connected (on each of the four jumpers), phantom power is enabled.
This is the default (factory) position.
~ With pins 1-2 connected (on each of the four jumpers), phantom power is completely
disabled, even if the Phantom Power Switch is UP . This setting is recommended for
low output mics that do not require phantom power, or for any unbalanced mics.
CAUTION If you choose to change the phantom power jumpers, always change both jumpers
for the selected mic. If you do not, damage may result to your microphone.
SW1 is the Status Dip Switch that is used to set the channel status on the AES outputs. The
switch is an eight-position DIP all of which are active. Switch shows default factory switch
settings.
