Audio Input interface
9.
It provides four audio(2 pairs) input interfaces, 5dBu, impedance≥47K,
RCA connector.
Audio Output interface
10.
It provides two audio output interfaces, 5dBu, impedance≤500Ω, RCA
connector.
Video Input/Output Interface (BNC)
11.
It provides two pairs of Composited Video input/output interfaces, and a
group of component signals. It will transmit the corresponding
component signal according to the selection of the signal source.
As shown in Figure 4.2-3, the relationship of the signal sources and the
interfaces are shown as in Table 4.2-3:
