Changing AES-3 impedance
The use of twin-and-screen cable is recommended for both
inputs and outputs.

Wiring the unit
AES-3 input and output impedances default to 110 Ω. It is
possible to modify this for each input and output pair to match
the AES-3 id standard of 75 Ω. Jumper positions located on
the main PCB motherboard (see above) determine whether an
input or output pair’s impedance is 110 or 75 Ω. Jumpers are
not factory tted. Adding the jumper will set the impedance to
75 Ω.
