1. Overview
Welcome in the EVS range of products and thank you for using an EVS XT2+
server. We will do our best to satisfy your video production needs and we look
forward to continuing working with you.
The EVS XT2+ servers are full digital in PAL (625i), NTSC (525i), 720p, 1080p or
1080i standards. These multi-channel, disk-based video servers are ideal for a
wide range of broadcast applications, from sports and live production to playout
and transmission.
XT2+ servers work with SAS disks: they are equipped with internal SAS disk array
and/or can be connected to a SAS-HDX external SAS disk array.
1.1 XT2+ HIGH-RESOLUTION SERVER
The XT2+ 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, or EVS’ AVSP, EditRec,
LinX API. XT2+ series servers can also be controlled by EVS applications:
Live Slow Motion (LSM) for sports production, including replays, highlights
editing, and analysis tools like Split Screen to compare 2 synchronized actions
side by side, Target Tracking and Painting to highlight a particular detail or
provide tactical explanations.
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.

1.2 XT2+ PROXY SERVER
A low-resolution option can be set up to use the XT2+ server as a proxy server
only. The Proxy servers can be run on large production events as the counterparts
of the high-resolution servers. In this case, they need to be included in an XNet
network distinct from the high-resolution XNet network.
The XT2+ proxy servers are used for browsing purposes and can be controlled by
IPDirector or EVS’ own API (AVSP) protocols.
1.3 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.

1.7 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 XT2+ chassis, support guides are required for
this unit into the rack mount. The front ears of the XT2+ unit are not designed to
support its full weight. Applying full weight on these might result in bending the
metal plate.

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 M-JPEG 30Mbps for standard definition and M-JPEG
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 XT2+:
Encoding File Header
