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, i njury or accident occurs due to negligent, incorrect or inappropriate operation of the product.
The lightning flash within an equilateral triangle is intended to alert the user to the presence of uninsulated dangerous voltage within the device that may be sufficient enough to constitute a risk of electric shock to users.
The exclamation mark within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance instructions in the literature accompanying the product.

Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
Do not use this apparatus near water.
Clean only with dry cloth.
Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
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.
Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
Only use attachments/accessories specified by the manufacturer.
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.
Unplug this apparatus during lightning storms or when unused for long periods of time.
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.

Trouble 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.

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.

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 (4, 6) show that the antenna power supply is working. The red LEDs “Owl” (5, 7) 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 internal 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 ( 8,13 ).
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 14. Switch on the antenna splitter with the on/off switch 3.

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.
