INFRAREDCONTROLTRANSMITTERSI1019 A
Introduction
The SI1 019 A is an intrared transmitter tor wireless multi-channel systems, wh ich are used in
conterence and interpreter installations. Its tunction is to process sound signals in the way that they
can be transmitted to a multi-channel receiver through invisible intrared light. In the receivers
EKI1 019-6, EKI1 019-9, EKI1 019-12 the modulated intrared signal will be transtormed again into
audible signals.

The unit is build up in 19"-modular technique and is mainly composed ot the tollowing componets:
housing SIG 1019, chassis SIC 1019 A 20, power supply module SIS 1019 A 20 and channel
module SIK 1019 A (channel 0 to channeI11).
Description of components:
)i
Chassis SIC 1019 A 20
The 19"-chassis ofters enough space tor one power supply module SIS 1019 A 20 and 9 channel
modules SIK 1019 A. It contains a mains transtormer, the rear wiring tor connecting the separate
channel modules as weil as the output sockets tor the RF-connections to the intrared radiators
SZI1 019 and SZI1 019 A. The chassis is suitable tor installation in 19"-racks but can also be used
as a table top unit together with the housing SIG 1019 or the carrying case EMK 1036. Unoccupied
module places can be covered with the cover plates SIB 1019.
The chassis comes with the mains cord
VZN 1010-1.
Power supply module SIS 1019 A 20
This module delivers the power required tor the channel modules as weil as tor the SZI1 019
radiators. Its section tor the channel modules is split up into!wo separately stabilized units, one tor
positions 0 to 3 and a second one tor positions 4 to 8. it one ot the supply voltages breaks down
one ot the LEDs @,0, or @on the tront panel will go out.
In addition to the stabilizer stages, the SIS 1019 A 20 has an RF master amplitier which mixes the
signals trom the channel modules and amplities them up to the level required by the intrared radia-
tors.

Channel module SIK1019
A
The signal from a mixing console etc. isted into the SIK 1019 A channel module.The balanced
input isadjustable tor input levels ranging trom 60 mVto 3 V.A high-grade limiter eliminates over-
modulation where the input level istoo high. The RF-outputsignalot the channel module isted into
the RFmasteramplitier ot the SIS1019 A 20.
The SIK 1019 A is available in 12 versions according to the 12 possible intrared channels K 0 -
K 11, which are named behind the designation (example: SIK 1019 A K 1).
The On/Oft switch W, the level control @ and the modulation control @)are situated on the front
panel.
Mechanics
- The chassis issuitable tor installationin 19"-racks.The AF-cabling is done on the tront side but
can be changed, if necesary, to the rear. As the AF-connections are accessible on the rear wiring
~P.C. board the electrical connection is easily done. The AF-sockets, which must be retrotitted, can
,Jbe installed in the rear sheet metalot the chassis or in the rack.
- After turning the plastic teet ot the metal housing by 1800 the SI1 019 A is stackable wlth other
units. For that unscrew screws A and Band turn the teet (see tig. 2 + 3).

Mains supply
Ex works the chassis is prepared lor operation at 220 VI 50 - 60 Hz. For operation at 110 V mains
two additional wire bridges have to be solde red in (see lig. 6
+ 7).
AF-connection
The AF-inputs are balanced and designed lor signal levels 0160 mV - 3 V.
Connectionof power radiator SZI1 019 A
The modulated RF-signal with a level 012 Vpp (source impedance 60 Q) is available at RF-output
sockets @ and @. They are decoupled lram each other and connected in parallel. The connec-
tion to the radiator is to be done with 50 Q-coaxial cable. For that Sennheiser offers the lollowing
cables: AV 20 (20 m), GZL 1019 A 10 (10m). GZL 1019 A 5 (5 m) and GZL 1019 A 1 (1 m). The si-
gnal is looped Irom the lirst radiator to the second, lram the second to the third etc. (see user's
guide SZI1 019 A). Max. 100 radiators may be connected in senes. The max. cable length between
the transmitter and the last radiator shouldn't exceed 1500 m. IIthe cable length ISmore than 300 m
the output 01the last radiator has to be terminated with 50 Q in order to prevent standing waves.

Operation
After all cable connections have been established actlvate the set with switch @ and the channel
modules with switch CD.
Note: Unused channel modules should be sWltched off, as in multi-channel units the total radiation
power is splitted evenly between all channels. This means that the covered area will be reduced
in accordance to the number 01channels in use.

Adjustment of modulation
For adjusting the modulation each chan ne I module is equipped with a sensitivity control @.The
optimum adjustment is reached when the red LED-s of the modulation indicator @)light up at level
peaks. If, inspite of correct adjustment, the input signal exceeds its normal value for short periods, a
high quality limiter prevents overmodulation. Up to 30 dB overmodulation will be controlled without
increasing distortion. The limitation is even useful in some cases, for example if facing widely differ-
ing sound levels.
Enlargement of the 9-channel-system to 12 channels
For enlarging an existing 9-channel-system to 12 channels a second chassis SIC 1019 A 20,
apower supply module SIS 1019 A 20, three channel modules SIK 1019 A and six cover plates
SIB 1019 are necessary. Both chassis are to be linked by interconnecting the L sockets @ of both
units.
The radiators can be connected to elther the first or the second transmitter, as the output signal of
both transmitters is identical.
