1. Overview
Welcome in the EVS range of products and thank you for using an EVS XS server.
We will do our best to satisfy your video production needs and we look forward to
continuing working with you.
The EVS XS series servers are full digital in PAL (625i), NTSC (525i), 720p, 1080i
and 1080p standards. These multi-channel, disk-based video servers are
specifically designed for studio applications, to satisfy the needs of near-live and
pre-recorded studio productions.
From Multicam version 10.03, the XS server is available in two versions:
•XS: equipped with internal SCSI disks and which can be connected to an XT-
HDX external SCSI disk array
•XS-SAS: work with SAS disks. It is equipped with internal SAS disk array
and/or can be connected to a SAS-HDX external SAS disk array.
1.1 XS HIGH-RESOLUTION SERVER
The XS server is typically used as a high-resolution server with various third party
controllers, applications and automation systems using industry-standard
protocols such as Sony BVW75, VDCP, Odetics, DD35, IPDP, or EVS’ AVSP,
EditRec, Linx API.
XS series servers can also be controlled by EVS applications:
IPDirector: a suite of Windows software applications designed to manage
networked EVS video servers. Its applications make it possible to control multiple
channels within the XNet network, as well as to log an event, to create and

manage clips and play-lists with advanced functions, among others to extract clips
from a VTR. It also provides extensive database search features.
INSIO: an interface to manage single or multi-camera ingests, instant review, clip
transfer and streaming to editor and storage, as well as production notes.
1.2 UNPACKING
Upon receipt of the equipment examine packing for obvious signs of damage. If
damaged, do not unpack and inform the carrier immediately. Check thanks to the
included packing list if all the items are present and if they show any mechanical
damage. If yes, report damage or the missing parts to EVS or their appropriate
representative.

ENVIRONMENTAL CONDITIONS
Temperature: 0°C to + 50°C (32°F to 104°F) ambient with free air flow
Relative humidity: 0% to 90% (non-condensing)
Cooling requirements: Forced air cooling air flow from front to back
Handling/movement: Designed for fixed use when in operation
Storage and transportation temperature: 0°C to +70°C (32°F to 158°F)
Storage and transportation relative humidity: 0% to 90% (non-condensing)
HOT SWAP SECONDARY POWER SUPPLY
A 2nd power supply (hot swap) for the disk recorder unit is available.
This additional power supply should be connected to mains to allow automatic
power switching to the second power supply would the first one fail.
The external ADA rack is fitted with an AUTOSWITCH power supply.
GROUNDING
Ensure the disk recorder unit is properly grounded at all times to avoid electrical
shock hazard.
1.6 VENTILATION & RACK MOUNTING
Adequate ventilation is obviously required for optimum performance. As a result of
this consideration, ensure no other equipment is located close to the mainframe.
Important
•Remember that fans are used to air cool the equipment and protect
it from overheating.
•Do not block fans intakes during operations.
Having regard to the weight of the XS chassis, support guides are required for this
unit into the rack mount. The front ears of the XS unit are not designed to support
its full weight. Applying full weight on these might result in bending the metal
plate.

1.7.3 VIDEO CODECS &BITRATES
SUPPORTED CODECS
The EVS XS server uses an intra-frame video encoding technique. The XS server
supports natively the following video codecs:
Codec SD HD Code Protection
MJPEG √√No
DVCPro 50 √- Code 9
IMX √- No
Intra-frame MPEG-2 - √No
Avid DNxHD® - √Code 5
Apple ProRes 422 - √Code 6
Apple ProRes 422 HQ - √Code 6
Apple ProRes 422 LT - √Code 6
DVCPro HD - √Code 8
AVC-Intra 100 - √Code 13
TARGET BITRATE RANGE AND DEFAULT VALUES
The target bitrate of the encoded video stream can be set by the user within the
accepted range: 8 to 100Mbps for standard definition, 40 to 250Mbps for high
definition with the exception of Apple ProRes, Avid DNxHD® and DVCPro codecs
working with defined bitrates.
The default values are MJPEG 30Mbps for standard definition and MJPEG
100Mbps for high definition.
The code-protected codecs are solely available when the corresponding code is
valid.

CONTENT TRANSFER ENCODING AND FILE HEADER
Up to Multicam 10.01, all codecs used in the EVS Video servers were encoding in
8-bit. From Multicam 10.03, it is possible to perform the encoding process in 8-bit
or 10 bit and to write a 10-bit file on selected codecs.
The following table summarizes the proposed configurations in the XS:
Encoding File Header
DNxHD 120/145 8-bit 8-bit
DNxHD 185/220 8-bit 8-bit
DNxHD 185x
DNxHD 220x 10-bit 10-bit
ProRes 120/145 8-bit 10-bit
ProRes 185/220 8-bit or 10-bit 10-bit
DVCPro HD 8-bit 8-bit
M-JPEG 8-bit 8-bit
MPEG 8-bit 8-bit
AVC-Intra 100 10-bit 10-bit
Note
When encoding in 10-
bit, it is not possible to use the graphic
functionality: Paint, Target, Logo Insertion and manual offside line.
1.7.4 RECORDING CAPACITY FOR XS SERVERS
