OPERATING ELEMENTS

CONNECTING SEVERAL RADIATORS

Starting with an infra-red modulator

WIDEBAND AND NARROW-BAND TRANSMISSION, SINGLE-CHANNEL AND MULTI-CHANNEL

INFRA-RED TECHNOLOGY

The SZI 1029 is a high power infra-red radiator. In a cordless infra-red sound transmission system it transforms the electrical signal delivered by an infra-red modulator or by an audio source into invisible infra-red light and radiates this IR light into a room. In contrast to radio transmission infra-red transmission is limited to the room, thus other systems can be operated in neighbouring rooms without interference.

The high-power radiator SZI 1029 is switched on by the IR carrier signal that is produced by the modulator. Commercially available 50 coaxial cables with BNC connectors are used for feeding sig nails from the modulator to the SZI 1029 radiator.

The infra-red radiator diodes in the high power radiator respond to the received signals and radiate modulated infra-red light. Depending on the model the radiator delivers a radiating power of 5 or 10W (see AVAILABLE MODELS).

WIDEBAND

Infra-red wideband transmission systems are chiefly used for transmitting audio signals in hi-fi quality.

The two available wideband channels (2.3 MHz and 2.8 MHz) are internationally standardized and are either used for two mono channels or for stereo transmission.

NARROW-BAND

Infra-red narrow-band transmission systems allow the transmission of up to 32 mono channels with a slightly reduced audio frequency response. They are ideal for multi-channel interpretation systems and multilingual information systems.

AREAS OF APPLICATION

Conference and simultaneous interpretation systems
High quality cordless sound transmission in recording studios or for hi-fi systems

PROPAGATION OF INFRA-RED LIGHT

The propagation of the infra-red signal radiated by the SZI 1029 can be compared to the propagation of normal daylight or artificial (lamp) light. Thus it is subject to similar conditions when it falls onto different materials:

IMPACT OF CURTAINS, CARPETS, AND PAINTS

• Dark and heavy materials, curtains, carpets, panellings, and wall coverings tend to absorb the light, a good reception can only be achieved in direct line of sight of the infra-red radiator.
• Roughcast and strongly structured wallpapers (such as woodchip, embossed or fabric papers) reflect the light unevenly but allow a more uniform propagation of the infra-red signal.
• Smooth and bright walls, smooth tiled floors and windows are highly reflective and are thus favourable for the propagation of in fra-red light.
• Different wall paints may reflect infra-red light differently although they have the same colour. This is due to the type and the composition of the paint pigmentation.

The power which is necessary to irradiate a room varies accordingly.

RADIATING POWER
Number of channels Example: 12
RADIATING POWER DURING MULTI-CHANNEL OPERATION

(Not for SZI 1029-T models) The number of transmitted channels has an impact on the radiated power of the infra-red radiator SZI 1029. The power is uniformly divided in such a way that, for instance, in a system with 12 narrow-band channels only 1/12 of the desired radiating power is available for each audio channel.

COMPUTING THE RADIATING POWER

RULE OF THUMB

PROPAGATION OF INFRA-RED LIGHT

During single channel operation (switch set to MONO), every SZI 1029 radiator will supply an area of about 1000~sq.m . The SZI 1029-10 radiators are able to supply approximately double this area.

When switched to narrow-band multi-channel operation (switch set to MULTI) power output and thus irradiated area are reduced by approximately 35% (see RADIATING POWER DURING MULTICHANNEL OPERATION).

A simple formula facilitates the calculation of the number of radiators necessary to irradiate a given room:

Number of radiators (SZI 1029) =

surface area in sq. m. x number of channels

650

Number of radiators (SZI 1029-10) =

surface area in sq. m. x number of channels

1300

The high power radiator SZI 1029 radiates the infra-red light in a lobar shape. With increasing distance the intensity becomes weaker. When a receiver leaves the irradiated area the transmission is interrupted. Receivers without squelch will produce a hissing noise, receivers with squelch will mute.

Insert the mains connector and secure it with the steel clamp.

Install the SZI 1029 high power radiator in a vertical (or almost vertical) position. The cables are guided downwards.

The vertical position ensures sufficient cooling of the radiator - air can circulate through the cooling fins that are integrated into the sides of the radiator.

The SZI 1029 high power radiator is provided with an interchangeable thread for mounting it to stands with 3/8'' or 1/2 , threads using an adaptor (included in the scope of delivery).

CONNECTING AN IR RADIATOR

After having connected the radiator to the mains, the IR input of the SZI 1029 has to be connected to the IR output of the modulator. Several co-axial cables are available for this purpose (see ELECTRICAL ACCESSORIES). The cables can be connected to one another using a BNC coupler GZV 1019 A.

IR input BNC
IR output BNC for extension radiators

For permanently installed systems you should use commercially available 50 coaxial cables, such as RG 58 (75 cables can be used if 50 cables are unavailable). If you want to use several SZI 1029 radiators you have to connect them in series. This is done by connecting the output BNC socket of the first radiator with the IR input BNC socket of the second radiator. A maximum of 100 radiators can be connected in series. The maximum total length of the cable should not exceed 1500m

After having connected the last radiator you can put the transmission system into operation by switching on the modulator. It transmits a carrier signal which automatically switches on the radiators. When the carrier signal stops, the radiators switch off automatically.

N.B.: In order to avoid standing waves a terminating impedance of 50 should be connected to the last radiator (or 75 terminating impedance if 75 cable was used).

SINGLE-CHANNEL/MULTICHANNEL OPERATION

Selector switch single-channel (Mono)/multi-channel (Multi)

The length of the cable between two neighbouring radiators should not exceed 75m , otherwise signal cancellation can occur when the radiation is not in phase! Do not forget the terminating impedance!

The SZI 1029 high power radiator is provided with 12 independent output stages, each stage amplifies the received signal for a power block of 12 infra-red LEDs. The SZI 1029-10 models with 24 independent output stages have double the power.

MALFUNCTION INDICATOR

If one power block fails, transmission quality is not considerably affected. Only if more than one third of all the blocks fail to operate, the red LED will light up in addition to the green one, thus indicating that the device will have to be repaired.

OPERATION INDICATOR

The indicators work as follows: Red Indicator Only: The radiator is connected to the mains but there is no IR signal present. Green Indicator Only: IR signal is present, the radiator is working normally. Red & Green Indicator: FAULT CONDITION! 30% or more of the diodes are not working and the radiator should be returned to your local Sennheiser agent for repair.

DISTANCE BETWEEN RADIATORS AND RECEIVERS

Please observe a minimum distance of 2m between radiators and receivers as otherwise the receiver input stage could be overloaded. This would result in a very poor transmission quality.

INSTALLATION

If possible the radiators should be installed in such a way that they are directly orientated towards the infra-red receivers. For best reception the radiators should be installed as high as possible with a slight downward inclination. For uniform irradiation of a given room the radiators should be installed decentralised, usually in the corners of the room.
