5.2 Signal earthing
Digital audio inputs are designed to have floating ‘signal low’ connections for cable
screens, with internal RC networks connected between cable screens and chassis ground.
This helps reduce the risk of high earth currents when AC power is induced into the cable,
or when an offset voltage exists between the product chassis and the local signal source
ground or chassis.
The internal RC network components fitted in the DIP2 and DIP2RS input cards are as
follows:
Component
Signal low (screen)
Chassis ground
1µF cap 10K ohm resistor
AES1 – , AES2 –
PCB GND
Notes:
Video and audio output cable screens are normally hard-wired directly to local chassis
ground.
