The Atlona AT-UHD-CLSO-612ED is an advanced six-input, multi-format switcher with 4K scaling,
Ethernet-enabled HDBaseT™, and PoE capabilities. It simplifies classroom and small office system
integration by providing two HDBaseT inputs, two HDMI inputs, two multi-function analog inputs,
plus mirrored HDBaseT and HDMI outputs. Advanced Automatic System Control (AASC) features
on the switcher provide automatic display control and automatic input selection. An internal
Ethernet hub in on the switcher enables control signal pass-through and network distribution. The
AT-UHD-CLSO-612ED contains a full RS-232 signal distribution system to route control signals to
local sources and displays. Professional audio features such as a microphone input with 48-volt
phantom power and ducking eliminates additional voice-lift audio needs. The switcher is configured
and managed by Atlona Management System software to reduce installation time and enable
remote support. The AT-UHD-CLSO-612ED addresses a wide array of AV switching and processing
needs often encountered in classrooms, conference rooms, boardrooms, training rooms and other
presentation settings.

Important! 4K (UHD) signals are sensitive to cable quality and installation technique. It is recommended to use CAT6a/7 solid core cables for best results.
Note: For cable distances see the specifications on page 34
Connector
Connector type and size is very important to ensure extenders work correctly. Please use the
matching cable type with the correct RJ45 connector.
CAT5e cables should use only CAT5e RJ45 connectors
CAT6 cables should use only CAT6 connectors
CAT6a cables should use only CAT6a connectors
CAT7 cables should use only CAT7 connectors
Using the wrong size connectors may result in interference causing loss of signal.
Important! “EZ RJ45 connectors” are not recommended with HDBaseT extenders. Doing so may result in interference
with audio and video transmission.

Analog Multi-Function Inputs
The CLSO-612ED multi-function analog inputs (Input 5 and 6) can be used with most analog video
signal formats including VGA (with DDC), RGBHV (without DDC), component (YUV), S-Video, or
composite video. Balanced analog audio can be input and embedded using the provided captive
screw connectors.
Each format can be directly accessed from RS-232, IR, or IP control. Front panel buttons sequentially
progress through each input format. The last format used is the first source selected when returning
to these inputs. Unused formats can be removed from the sequence using the WebGUI, RS-232, or
IP.
VGA (m) to BNC, VGA (m) to RCA, and S-Video to 2 BNC adaptors can be used to connect sources
to these inputs.
VGA
Use a VGA to VGA cable to ensure that the Preferred Resolution DDC is communicated to your
source.
RGBHV
Use a HD-15 (VGA) to 5 BNC breakout cable for this format. An existing RGBHV analog matrix
switch can be connected here to maintain full function of the analog matrix.
Component
YUV (YPbPr) signal from DVD (or other sources) can be input to the CLSO-612ED using the green (Y),
blue (Pb), and red (Pr) connections on a HD-15 (VGA) to 5 BNC breakout cable or with a common
VGA (m)-Component (3 RCA m) adaptor.
S-Video
YC signal from a VCR or teleconference system can be input to the CLSO-612ED using the blue (Y),
and green (C) connections on a HD-15 (VGA) to 5 BNC (m) breakout cable and a common S-Video (m)
to 2 BNC (f) adaptor
Composite
NTSC, PAL, or Secam video signals can be input to the CLSO-612ED using the blue connection on a
HD-15 (VGA) to 5 BNC (m) breakout cable.
A common application for this type of input would be to connect a RGBHV matrix switcher to the
CLSO-612ED. Then each input to the matrix could be connected to a different format analog signal.
A 3rd party control system could ensure the correct format is selected to match the input to the
switcher.

Analog Audio
A captive screw analog audio connector is provided to ensure a more reliable and secure
connection. The captive screw connector supports balanced and unbalanced audio output.
Balanced audio connections use two signal wires and a ground to minimize interference to an audio
signal over longer cable runs. Unbalanced audio connections use two wires for connection with
consumer audio components.
Audio can be routed to any input for use with VGA or other sources. View page 31 for commands.

Note: Pin outs may vary, please refer to the audio device’s manual to ensure a correct connection.
Important! When terminating cables, please ensure exposed adjacent wires do not touch. This may result in
a short that can damage connected devices.
