. Safety Instructions
General
• READ these instructions.
• KEEP these instructions.
• HEED all warnings.
Exemption from liability
• beyerdynamic GmbH & Co. KG will not be liable if any damage,
injury or accident occurs due to negligent, incorrect or inappropriate
operation of the product.
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with
the manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifiers) that
produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-
type plug. A polarized plug has two blades with one wider than
the other. A grounding type plug has two blades and a third
grounding prong. The wide blade or the third prong are provided
for your safety. If the provided plug does not fit into your outlet,
consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by
the manufacturer, or sold with the apparatus. When a cart is used,
use caution when moving the cart/apparatus combination to
avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused
for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way, such
as power supply cord or plug is damaged, liquid has been spilled
or objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has
been dropped.
Location
• The equipment must be set up so that the mains switch, mains plug
and all connections on the rear of the device are easily accessible.
• If you transport the equipment to another location take care to
ensure that it is adequately secured and can never be damaged by
being dropped or by impacts on the equipment.
Fire hazard
• Never place naked flames (e.g. candles) near the equipment.
Humidity / heat sources
• Never expose the equipment to rain or a high level of humidity. For
this reason do not install it in the immediate vicinity of swimming
pools, showers, damp basement rooms or other areas with unusually
high atmospheric humidity.
• Never place objects containing liquid (e.g. vases or drinking glasses)
on the equipment. Liquids in the equipment could cause a short
circuit.
• Do not install near any heat sources such as radiators, heat registers,
stoves or other apparatus (including amplifiers) that produce heat.
Connection
• The equipment must be connected to a mains socket that has an
earth contact.
• Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the point where
they exit from the apparatus.
• Lay all connection cables so that they do not present a trip hazard.
• Whenever working on the inputs and outputs of the equipment
switch off power.
• Check whether the connection figures comply with the existing
mains supply. Serious damage could occur due to connecting the
system to the wrong power supply. An incorrect mains voltage
could damage the equipment or cause an electric shock.
• Please note that different operating voltages require the use of
different types of power cable and plugs.
Please refer to the following table:
• If the equipment causes a blown fuse or a short circuit, disconnect
it from the mains and have it checked and repaired.
• Do not hold the mains cable with wet hands. There must be no
water or dust on the contact pins. In both cases you could receive
an electric shock.
• The mains cable must be firmly connected. If it is loose there is a fire
hazard.
• Always pull out the mains cable from the mains and/or from the
equipment by the plug – never by the cable. The cable could be
damaged and cause an electric shock or fire.
• Do not use the equipment if the mains plug is damaged.
• If you connect defective or unsuitable accessories, the equipment
could be damaged. Only use connection cables available from or
recommended by beyerdynamic. If you use cables you have made
up yourself, all claim to warranty is null and void.
• In order to disconnect the receiver from AC power, switch it off and
disconnect the power plug from the power socket.
Maintenance
• Only clean the equipment with a slightly damp or dry cloth. Never
use solvents as these damage the surface.
Troube shooting and servicing
• Do not open the equipment without authorisation. You could
receive an electric shock. There are no user-serviceable parts inside.
• Leave all service work to authorised expert personnel.
2. Disposal
• This symbol on the product, in the instructions or on the
packaging means that your electrical and electronic
equipment should be disposed at the end of its life
separately from your household waste. There are separate
collection systems for recycling in the EU. For more
information, please contact the local authority or your
retailer where you purchased the product.

4. General Information
• The WA-AS4 antenna splitter is a 4-way wideband antenna
splitter operating in the frequency range of 470 to 1,810 MHz.
• For the diversity operation the WA-AS4 is provided with two
identical antenna paths.
• For each antenna path there are four outputs available for the
connection of receivers.
• The operation is possible with antennas that are directly or
remotely connected.
• Each antenna input provides a supply voltage for active antennas
or antenna amplifiers. A maximum current output of 150 mA at
a voltage of 8 V DC is available for each input.
• The white LEDs "Ok" on the front side (, ) show that the
antenna power supply is working. The red LEDs "Ovl" (, )
indicate that the maximum current consumption of an antenna
cable (e. g. due to a short circuit) has been exceeded. In such a
case, the antenna supply voltage is switched off automatically.
• The WA-AS4 provides two DC outputs. These outputs are
designed to drive one TG 500SR each. This eliminates the need
for space-consuming external AC/DC power adapters in mixed
setups of TG 500SR and TG 500DR. The WA-AS4 itself has an in-
ternal switching power supply.
• The dimensions and design are adapted to the TG 500DR and TG
500SR receivers, to create an optimal interplay with the TG 500
system.

. Mounting and Installation
• Rack mounting of the WA-AS4 is possible with the supplied
mounting brackets. With these mounting brackets the WA-AS4
provides holes for installation in a 19" rack and cut-outs for
the installation of the BNC adapter WA-ADF for front mounting
of antennas .
• The split antenna outputs are connected to the antenna inputs of
the receivers via the supplied BNC patch cables (WA-CKL60). In
order to ensure the diversity operation, each receiver must be sup-
plied with an A and a B antenna signal!
• Two TG 500SR can be fed directly from the DC outputs of the
WA-AS4 via the supplied connection cables (, ).
• Both passive and active antennas (e. g. WA-ATDA or WA-ATDA
1G8) or antenna amplifiers (WA-AMP2) can be connected to the
antenna inputs. Active antennas or antenna amplifiers do not
require a separate power supply. Power is supplied directly from
the antenna input.
• Connect the antenna splitter with the supplied power cable to
an appropriate mains socket via the mains connection . Switch
on the antenna splitter with the on/off switch .

Important notes
• The antenna connections have a DC voltage of 8 V DC. In order to avoid a short circuit, they should not touch the housing of the rack.
• For the connection of remote antennas use the WA-AC5, WA-AC10 or WA-AC25 antenna cables The longer the cable, the higher the
attenuation of the high frequency signal.
• Connected antennas must be tuned to the frequency range of the connected receivers.
