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.
