7.3.3.11 LINE AUDIO SELECTION
The rear panel ‘AUDIO’ connector provides two sets of 600-Ohm input and output lines and connects one of
two external audio devices to the RT-9000 B . A typical use of this capability might be to allow convenient
switching in or out specialized terminal equipment such as audio processors, encryption equipment, etc.
To select either External Audio Line, depress the Feature Menu ‘MORE’ key successively until the display
shown in Figure 7.3.3.23 appears.
