110Ω. This loop-through input can be used to send the signal to multiple generators.
Keep in mind that this loop introduces a 0.4dB attenuation, equivalent to a loss of 5%
of the signal amplitude. Therefore, it is not recommended to have more than five
DAT3000C01 units connected using loop-through. If more than five units will be used,
the system engineer should perform the necessary calculations based upon the
length of the cabling and the signal amplitude in order to guarantee that the signal
level at the last module in the loop is always greater than 300 mVpp.
Digital audio outputs are balanced, use 3.81mm pitch terminal block connectors and
their characteristic impedance is 110Ω.
If an output signal in AES3id format is needed, an adapter as shown in the figure can
be built. Albalá Ingenieros does not provide this adapter
TWISTED PAIR TO COAXIAL ADAPTER AS PER AES3id
For digital audio connections 110Ω characteristic impedance, two-wire shielded cable
is preferred. The GND terminal allows connection of the cable shield.
3.7.2. Connections for analog video, word-clock and the delay signal
Coaxial cabling with a characteristic impedance of 75Ω such as RG59 should be used
to connect analog video, word-clock and delay signals.
If the loop-through feature will be used to send the signal on to other equipment,
make sure that the line is properly terminated at the endpoint.
