4. If the operating range of the transmitters is greater than the stage, the antennae can be
mounted vertically on the ceiling. The distance between the two GPA 700 receiving antennae
should be approximately half the total operating range.
Please note:
1. Install the antennae GPA 700 in the same area as the transmitter.
2. To avoid interference do not install the antennae near digitally controlled components.
3. Keep a minimum distance of 0.5 m from metallic objects, including reinforced concrete
walls or pillars.
4. Do not bend the antenna cables at the antenna input, and ensure that they are not
subjected to undue stress. For mounting the GPA 700 antenna use the AMK 700 mounting
device for strain relief of the antenna cable.

ZAS 500 Antenna Splitter
Up to four
NE 500 receivers can be connected to the ZAS 500 active antenna splitter. Any
outputs which are not used should be terminated with a true resistance of 50
!
(refer to
accessories). Make sure that you do not accidentally terminate an input with a true resistance.
For powering the ZAS 500 antenna splitter connect the external power supply unit to the
antenna splitter and to AC power. Switch on the ZAS 500 (green LED on the front panel is
illuminated).
Up to two ZAV antenna amplifiers can be connected to each antenna input. For powering the
ZAV switch on the ZAS 500 antenna splitter and switch the DIP-switches on the rear into the
ON position. The supply voltage for the antenna amplifiers is switched to the antenna cable.
If there is a short circuit in the antenna cable the supply voltage is switched off automatically.
Furthermore, the supply voltage can also be switched off with the DIP-switches A and/or B.
