2 BELANGRIJKE VEILIGHEIDSINSTRUCTIES
Lees deze handleiding zorgvuldig door om het beste uit uw product te halen. Bewaar
het op een veilige plek voor raadpleging in de toekomst.
Haal nooit het omhulsel van de eenheid af, dit om de kans op een elektrische schok
te verminderen. Maak het apparaat nooit open: er bevinden zich geen door de
gebruiker in te stellen onderdelen in het apparaat. Laat service en onderhoud over
aan een gekwalificeerde technicus.
2.1 Elektriciteit en aansluiting
Deze eenheid is niet van de wisselstroom voedingsbron gescheiden wanneer de
stekker nog in het stopcontact zit. Wanneer de eenheid uitstaat, staat deze nog in de
stand-by modus. In de stand-by modus vergt de eenheid minder stroom dan in de
normale "aan" modus.
Wanneer u de eenheid voor langere tijd niet gebruikt, zorg er dan voor dat de
stekker van het wisselstroomsnoer uit het stopcontact is getrokken.
Het wisselstroom stopcontact moet dichtbij de eenheid geïnstalleerd worden en
makkelijk toegankelijk zijn.
Als de eenheid duidelijk beschadigd is moet u deze nooit op het lichtnet aansluiten of
bedienen.
2.2 Water en vocht
Om het risiko op brand en persoonlijk letsel te beperken is het gebruik van dit
apparaat buiten en/of blootstelling aan regen, water of overdadige hoeveelheden
vocht uitdrukkelijk verboden.
Het apparaat mag niet worden blootgesteld aan druppels of bespatting en er mogen
geen objecten die gevuld zijn met vloeistoffen, zoals vazen, op het apparaat
geplaatst worden.
2.3 Algemeen onderhoud
Forceer schakelaars of externe aansluitingen nooit.
Bij verplaatsing van de eenheid, de seriële poortaansluitingen eerst loskoppelen, dan
de voedingskabel en als laatste de snoeren naar andere apparaten.
Probeer de eenheid nooit met chemische oplosmiddelen of schoonmaakmiddelen in
een spuitbus schoon te maken, omdat dit de eenheid kan beschadigen. Gebruik een
schone droge doek.

12
2.4 Plaatsing
Deze eenheid moet geïnstalleerd worden op een koele droge plaats, uit de buurt van
bronnen van extreme hitte, vibraties, stof, vocht en kou.
2.5 Ventilatie
De sleuven en openingen aan de zijkant van de eenheid zijn voor ventilatie. Zorg er
voor dat de eenheid op een goed geventileerde plek geïnstalleerd wordt zodat deze
betrouwbaar werkt.
2.6 Intellectueel eigendom
Sommige IC chips in dit product bevatten vertrouwelijke informatie en/of
fabrieksgeheimen. U mag daarom de inhoud hiervan niet kopiëren, wijzigen,
aanpassen, vertalen, verspreiden, nabouwen, of decompileren

3 DEVICE SUMMARY
3.1 Device Capabilities
The S2 series of switcher units are predominantly designed as input port expanders
for the CORIO®C2-1000, C2-2000 and (for some S2 units) C2-7000 series Scan
converters and scalers – although they can also be used as stand-alone signal
switchers. They are a family of compact (half-rack), high bandwidth, high
performance routing switchers designed to meet the most demanding requirements
for signal routing.
Complementary to the range is the S2-101AA stereo audio power amplifier,
providing at least 10 Watts per channel into 4 ohm speakers, from audio signal levels
provided by the rest of the range.
S2 range switchers are available to support most common types of video signal
formats including RGBHV, RGBS, RGsB, YPbPr, Composite Video, S-Video (Y/C)
and DVI as well as stereo audio balanced and unbalanced. EDID and HDCP are
also supported on some models with resolutions up to UXGA.
Some units (typically those ending with ‘A’ such as the S2-105PCA) support “audio
follow video” switching. The S2-106AD stereo audio switcher also includes
adjustments for volume, balance and audio delay up to 1 second for lip-sync - all
controlled via an easy to use menu.
The S2 range is designed with ease of use and reliability in mind, utilizing intuitive
simple to use controls and interfaces, as well as rugged metal cases for robustness
in tough environments.
The switchers can be used stand alone, or when combined with the CORIO®series
scan converters and scalers, form a powerful toolset for high quality audio video
signal processing for virtually any application.
3.2 Device Features
Simple control
Each unit can be controlled in various ways. One option is to control using the keys
on the front of the unit. Another option would be to control the unit from an infra-red
remote control. They can also be controlled via RS-232 using the Windows®Control
Panel which is available for download from our Internet site
Upgradeability
All S2 units benefit from firmware upgradeability, thus reducing product
obsolescence by allowing the installation of the latest version of firmware. This only
applies to the software used to control the unit, and not its actual functionality. Some
units may be able to benefit from the addition of new features, but the majority of S2
units have a dedicated architecture. See http://www.tvone.com/support for more
detail.

4 PRODUCT IMAGES
Your S2 unit should look like one of the images below.
Video switchers support switching of PC, composite, YC and DVI video signals, and
models with an A suffix additionally support stereo audio.
The S2-106AD supports five fully balanced stereo inputs, one un-balanced PC audio
input and a balanced output with an LCD display, whilst the S2-101AA stereo audio
power amplifier supports balanced and un-balanced stereo inputs and 4 ohm
speaker outputs.
