Thank you for selecting the Stegos wireless digital boundary microphone system. Please take some time
to read carefully through this manual before setting up the equipment.
The wireless Stegos system includes receiver and boundary microphone and has been developed
especially for the use with video conference systems. Up to three Stegos systems can be operated in
neighbouring rooms simultaneously.
1. Safety and environment
1.1 Stegos RS receiver
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 install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
8. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles,
and the point where they exit from the apparatus.
9. Only use attachments/accessories specified by the manufacturer.
10. Unplug this apparatus during lightning storms or when unused for long periods of time.
11. 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.
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.
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.
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.

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 equipment switch off all inputs and outputs to the power supply.
• 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.
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.

110 - 125 V UL817 and CSA C 22.2 no 42.
220 - 230 V CEE 7 page VII, SR section 107-2-D1/IEC 83 page C4.

1.2 Stegos TB boundary microphone
• Protect the boundary microphone from moisture and sudden impacts. You could either injure yourself
or others or damage the microphone.
• Never take batteries apart yourself. The battery acid contained will damage skin and clothing.
• The boundary microphone does not contain any user-serviceable parts inside. Dismantling the
microphone yourself may invalidate the guarantee.
• If the rechargeable battery is exhausted after several years, please contact your dealer for an
appropriate exchange.
1.3 Disposal
• Old batteries may contain substances that are harmful to your health and environment.
• The device provides built-in rechargeable batteries, which you cannot remove yourself, therefore,
return the device to your dealer for recycling when the batteries are exhausted.
• All batteries are recycled to reclaim valuable material such as iron, zinc or nickel.

2. Stegos RS receiver
The receiver provides three different connections for video conference systems: 3-pin Phoenix terminal
strip, mini jack (3.5 mm) and 3-pin XLR. The individual microphone signals are available via a multipin
Phoenix terminal strip. For the data exchange with media control systems or PC there is an RS 232
interface and a USB connection available. The channel LEDs display which channel is occupied (red) or
available (green). Up to four acoustical boundary microphones can be operated with one receiver.

2.2 How to connect the antennae
Connect the antennae to the antenna sockets .
Please note that for diversity operation both antennae have to be
connected. A weighting circuit silently makes sure that the better
antenna signal is received.
2.3 Where to place the receiver
• Place the Stegos RS receiver in the same room where the
transmission takes place. Make sure that the receiver is placed on
the same table height as the Stegos TB boundary microphone.
• Avoid shadowing effect of the Stegos RS antennae, especially by
metallic surfaces.
• A free line of sight between the Stegos RS receiver and the
Stegos TB microphone is ideal. Big obstacles in between can
possibly affect the radio transmission. In such specific installations
the use of remote antennae can possibly achieve an improvement
of the RF situation.
2.4 Connection
• Connect the Stegos RS receiver to your video conference system.
There are three different connections:
3-pin Phoenix terminal strip
Mini jack (3.5 mm)
3-pin XLR
• Connect the power cable to the mains connection and to the
power socket.
• If you want to control or monitor the system via PC connect the
USB connection to a PC.

2.5 How to operate the receiver
• Turn on the receiver with the on/off switch . The green power
on LED will illuminate.
• The channel LEDs 1 to 4 will illuminate green to indicate the
availability. As soon as you turn on the first Stegos TB boundary
microphone, the channel LED 1 will illuminate red to indicate
that the channel is occupied.
• At the factory the RF band “Low” has been adjusted. If interferences occur, you should change the frequency band. Use the
tip of a pencil or a paper clip to press the countersunk pushbutton for RF band selection . The boundary microphones are
automatically set to the selected frequency band.
