1. Introduction
System Overview
System Overview
This section provides a complete overview of the AirCleaner system.
Description
AirCleaner is a solid-state, all-digital video and audio delay machine for use in live-
to-air television broadcasts. AirCleaner is designed as a protection against “wardrobe
malfunctions,” spoken profanities, or any type of unwanted broadcast content.
AirCleaner offers multiple operating modes with the ability to mask video offenses
with an auxiliary “safe” video source or a defocused live image. AirCleaner will mask
audio offenses with an auxiliary “safe” audio source or with a mute. Refer to
Chapter 4: “Operations” on page 45 for more information.
AirCleaner can be operated with either one or two “screeners” (operators that censor
the live audio/video feed). In the case of two-screener operation, the total program
delay internal to AirCleaner can be divided between the two users (in any proportion
desired).
AirCleaner operates with either High-Definition (HD) or Standard-Definition (SD)
digital video, with all of the popular video formats supported. It’s equipped with two
SD/HD SDI video inputs, two SD/HD SDI video outputs and has an analog reference
input. AirCleaner handles eight channels (4 stereo pairs) of AES/EBU audio for each
of the two video I/O streams. AirCleaner can also utilized digital audio that’s
embedded in the digital video I/O streams.
AirCleaner also features a single stereo analog audio monitoring output on a 3.5mm
jack. Refer to Chapter 2: “Installation” on page 5 for more information.
System Options
AirCleaner comes in two model configurations. Model 1 features 12 seconds of HD
delay (which corresponds to 60 seconds of SD delay). Model 2 features 6 seconds of
HD delay (which corresponds to 30 seconds of SD delay). For both AirCleaner
models, there are three system options available:
•Redundant Power Supply
•Panic Button Control Panel
•Panic Button “Y” Cable
Redundant Power Supply
This option allows for dual power supplies to guard against complete system
failure in the event of a single power supply failure. The AirCleaner will run on a
single power supply; however, when the redundant supply is fitted, both power
NOTE In SD 525 and 625 operation, AirCleaner supports only 4-track
(two stereo pairs) of embedded digital audio, as defined by SMPTE
specification.

System Overview
supplies share the power load. In the event one of the redundant power supplies
fails, the remaining operational power supply will automatically take over
complete power load for AirCleaner.
Panic Button Control Panel
The Panic Button Control Panel is a simple two-button user interface (one button
for Video, the other for Audio) that sits on a desktop and is connected to the
AirCleaner main chassis via a 9-pin cable.
Figure 1-1. Panic Button Control Panel
The Panic Button Control Panel is used to trigger the video and/or audio mask in
the event of a visual or aural offense. Pressing the specific button (AUDIO or
VIDEO) will tell AirCleaner to mask the content according to how the AirCleaner
was previously programmed via the main chassis user interface. The masking will
continue for the duration the button is held down.
The Panic Button Control Panel connects to the system mainframe via simple GPI
connections. Most facilities will want to design their own Panic Button Control
Panel to fit their workflow; however Abekas provides this option for those
customers who don’t wish to build their own control panels. The Panic Button
Control Panel ships with a 33-foot shielded cable for connection to the GPI
connector on the AirCleaner main chassis.
Panic Button “Y” Cable
In some instances, AirCleaner can be operated in a “two screener mode” which
requires a second Panic Button Control Panel. In order to connect two Panic Button
Control Panels to the AirCleaner main chassis, this customized “Y” cable is
required. This “Y” cable is connected to the rear of the AirCleaner chassis, and
then the control cables for each of the two Panic Button Control Panels are
connected to the “Y” cable.
NOTE All options ordered at time of sale will be installed and tested with
the AirCleaner chassis. All options ordered after time of sale will
ship with detailed installation instructions. If there are any
questions regarding installation of these options, please contact
Abekas technical support.
NOTE Pin-outs for the Panic Button “Y” cable are provided in Chapter 2.
These are simple GPI connections, easily built at the customer’s
site, thus allowing for more specific and custom installations.

Cooling and Airflow
Cooling and Airflow
AirCleaner has two fans mounted in the front of the chassis, which force air from the
front, through the chassis, with warm air exhausting out air vents located on the rear
panel. These fans should be periodically checked to ensure they are operating
properly; the front and rear air vents should be kept clean and clear at all times.
Figure 2-1. AirCleaner Chassis Airflow
The Panic Button Control Panel has no special cooling or airflow considerations.
Power Consumption
The AirCleaner main chassis consumes a maximum of 300 watts (average operating
power is about 60 watts). An optional redundant power supply is available; when it’s
installed and in operation, the main and redundant power supplies will share the
power load equally and will therefore not change the overall power consumption.
There is no AC power connection to the Panic Button Control Panel.
WARNING AirCleaner uses open-module power supplies with:
UNUSUALLY HIGH CURRENT and VOLTAGES!
The power supplies should NEVER have external AC power
connected when the chassis top cover is removed.
Risk of DEADLY electrical shock is EXTREMELY HIGH!
Always remove all AC power from main chassis BEFORE removing
the chassis top cover. For units fitted with the redundant power
supply option, be sure to remove BOTH AC power cords.

Video Connections
Video Connections
All video inputs and outputs (with the exception of REF IN) are serial digital (SDI) and
all must operate with the same video line standard at the same time.
All video connections are provided on female BNC. Each BNC has an LED
associated with it and in the case of inputs (PGM IN, AUX IN and REF IN), will
illuminate solidly when an input is detected and locked. If the LED is not illuminated
or is flashing, then a problem is detected. The SDI digital video outputs (PGM OUT
and TAP OUT) have LED’s that are illuminated whenever power is on.
Figure 2-5. Rear Panel Video Connections
PGM IN – Video
(Live Video Input)
This is the main program digital video input feed that will be delayed by AirCleaner.
This digital video input can be either Standard-Definition (SMPTE 259M / EBU-Tech
3267-E) or High-Definition (SMPTE 292M). The programmed video format of this
video input will always follow the configuration of the video output. This digital
video input can carry up to eight tracks (four stereo pair) of embedded digital audio.
PGM OUT – Video
(Delayed Video Output)
This is the delayed “Live to Air” serial digital video output, which will feed the
transmission path.
This digital video output can be either Standard-Definition (SMPTE 259M / EBU-
Tech 3267-E) or High-Definition (SMPTE 292M). The video format and line standard
for this output is configured in the Option Menu; this selection will be the same for all
the video inputs and outputs. This digital video output can carry up to eight tracks
(four stereo pair) of embedded digital audio.
NOTE All video inputs and outputs can also accept embedded digital
audio and are user selectable. Refer to Chapter 4 - Operations for
more information.

AUX IN – Video
(“Safe” Video Input)
When the AirCleaner is programmed to switch to the auxiliary input during a VIDEO
Panic Button press, this is the “Safe” digital video input into AirCleaner that is used
for the safe feed. If AirCleaner is programmed to defocus the video during a VIDEO
Panic Button press, then this input is not used.
This digital video input can be either Standard-Definition (SMPTE 259M / EBU-Tech
3267-E) or High-Definition (SMPTE 292M). The programmed video format of this
video input will always follow the configuration of the video output. This digital
video input can carry up to eight tracks (four stereo pair) of embedded digital audio.
TAP OUT – Video
(Screener 2 Monitor Video Output)
This digital video output is used only during “two screener” modes, in which there are
two separate users that are operating in series. This video output is downstream from
the video delay used by the first screener, and is used by the second screener to
monitor the video coming in to the second screener’s video delay pathway.
This digital video output can be either Standard-Definition (SMPTE 259M / EBU-
Tech 3267-E) or High-Definition (SMPTE 292M). The video format and line standard
for this output is configured in the Option Menu; this selection will be the same for all
the video inputs and outputs. This digital video output can carry eight tracks of
embedded digital audio.
REF IN
(Reference Input)
This input to AirCleaner accepts an external analog reference signal, either Bi-Level
or Tri-Level, that must match the frame rate of the incoming video signal. SD video
can only be locked to a Bi-Level external reference signal (or to the video input or
free run). HD video can be locked to either Tri-Level or Bi-Level reference, as long as
the frame rate of the video and the reference signal are matched.
The reference signal will lock both the PGM OUT and TAP OUT together in time with
the reference signal. The reference input is internally terminated (no loop-thru).
Reference can also be programmed to lock to the video signal present on the PGM IN
or the AUX IN. There is also a reference “Free Run” selection. All reference selections
are made in the Option Menu.
NOTE All video inputs and outputs can also accept embedded digital
audio and are user selectable. Refer to Chapter 4 - Operations for
more information.
