Section 7: Installing audio inputs
This section describes how to route audio input wiring to the NX50’s exciters.
Planning complete?
1. Make sure you have read and fully understood the audio input options described in the
NX50 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 and connecting audio inputs
1. Route all audio cables from their audio sources to the top of the transmitter. Two
possible entry holes are provided to accept audio input wiring (see Figure 7.2 on page
7-3 ).
2. Punch the appropriate size hole in the desired audio entry plate as follows:
– Remove the left-hand or right-hand entry plate (see Figure 7.2 on page 7-3 ) from
the top of the cabinet. Each is secured using two M4 screws and has a pre-cut,
centered 1/4-inch diameter hole.
– Use a chassis punch tool (e.g., Greenlee, etc.) to punch the desired size hole in the entry
plate. Make sure the audio input cables will pass safely through the hole. If necessary, you
can remove the plate completely to gain access to a smaller, rectangular hole.
– Install a conduit termination on the entry plate, if desired.
– Re-install the entry plate on top of the transmitter using two M4 screws.
3. Obtain two ferrite toroids (Nautel Part # LXP44 and either one of Nautel Part # LP23 or
LXP38) from the ancillary kit.
4. Pass all audio input cables through the ferrite toroids obtained in Step 3 . If practical,
wires should pass through a minimum of two times (two turns) (see Figure 7.1 on page
7-2 ). Position the ferrite toroids just outside, or just inside, the audio input entry hole.
