5. Route the audio input cables through the selected entry hole and toward the exciter panel
(A11), located behind the front door (see Figure 7.3 on page 7-4 ). If possible, install
exciter mating connectors after passing cables through the entry hole. Route all wiring
from the top of the cabinet to the hinged side of the exciter panel to allow the panel to
open.
6. With the audio input cables near their destination, cut each wire to the required length and
install connectors, as necessary.
7. Remove plastic cap-plugs from the connectors on the exciter panel, if applicable.
8. Connect the appropriate audio input cable(s) to the connector(s) shown in Figure 7.3
on page 7-4 . Secure cables to the existing cabling and to the panel using arrowhead
tyraps (Nautel Part # HAC15) in the ancillary kit (see Figure 7.3 on page 7-4 to locate
tyrap anchor hole locations).
9. If you are using an external USB device as your playlist, connect the USB device to a USB
port on the SBC. Ensure the optional USB Sound Card is connected to another USB port on
the SBC and the output of the USB sound card is connected to one of the AES inputs on the
control/interface PWB. Refer to the Operations and Maintenance Manual for details on
using the Audio Player’s Playlist feature, available through the AUI.
