Section 8: Installing audio inputs
This section describes how to route audio input wiring to the NX300’s exciters.
Planning complete?
1. Make sure you have read and fully understood the audio input options described in the
NX300 Pre-installation Manual before proceeding.
2. Make sure the audio input wires are long enough to allow routing through the top of the
transmitter cabinet and down to the exciter panel.
Routing cables
1. Route all audio cables from their audio sources to the top of the transmitter (left-hand).
2. Get two ferrite toroids (one each of Nautel Part # LXP44 and LP23) from the ancillary kit.
3. Pass all audio input cables through the ferrite toroids obtained in Step 2 . If practical, wires
should pass through a minimum of two times (two turns) (see Figure 8.1 on page 8-2 ). An
entrance is provided at the top of the transmitter to accept audio input wiring (see Figure 8.2
on page 8-3 ). Position the ferrite toroids just outside, or just inside, the audio input entry
hole.
4. Route the audio input cables through the entry hole and toward the exciter panel (A11),
located behind the front door (see Figure 8.3 on page 8-3 ). If possible, install exciter mating
connectors after passing cables through the audio input entry hole.
5. With the audio input cables near their destination, cut each wire to the required length and
install connectors, as necessary.
6. Remove plastic cap-plugs from the connectors on the exciter panel, if applicable.
7. Connect the appropriate audio input cable(s) to the connector(s) described in Section 7 of
the NX300 Pre-installation Manual .
