SECTION 2.7: INSTALLING PROGRAM INPUTS
This section describes how to route program input wiring to the GV10/GV7.5’s exciter(s).
Planning Complete?
1. Make sure you have read and fully understood the program input options described in the GV10/
GV7.5 Pre-installation Manual before proceeding.
2. Make sure the program input wires are long enough to allow routing through the top of the
transmitter cabinet and down to the rear panel of exciter A and exciter B (if applicable).
3. If you ordered the optional Exciter Upgrade kit, make sure it is installed (see “Upgrading to Dual
Exciter” on page 2.3.2 ). The transmitter is factory configured with a single exciter (exciter A, A5).
4. If you ordered the optional Orban Inside Audio Processor kit for one or both exciters, as applicable,
make sure it is installed (see
“Installing the Orban Inside Card” on page 2.3.4 ). The transmitter’s
exciters are factory configured with no Orban Inside audio processor card.
Routing Cables
Route the desired analog and digital program input cables to the back of the GV10/GV7.5’s exciter(s).
1. Route all program input cables from their audio sources to the top of the transmitter. If you are
using dual exciters, you will need two sets of program inputs - one for each exciter.
2. Get two ferrite toroids (Nautel Part # LXP38, 19 mm inner diameter) from the ancillary kit for each
exciter installed.
3. Pass all program 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 2.7.1 on page 2.7.2 ). An
entrance hole is provided at the top of the transmitter to accept program input wiring. Position the
ferrite toroids just outside, or just inside, the program input entry hole.
4. Punch the appropriate size hole in the program input entry plate (see Figure 2.7.2 on page 2.7.3 ):
 Remove the program input entry plate from the top of the transmitter. It is secured using four
M4 screws and has a pre-cut, centered 1/4-inch diameter hole.
