Bosch microphone refurbishment

Replacement verses refurbishment
Bosch mic refurbishment
Bosch goose-neck microphone

Bosch Conference Solutions offer versatility, high audio quality and data transmission while providing complete control over your conference proceedings.

But, the metal goose-neck microphones eventually succumb to being manhandled and abused and will ultimately require replacement.

Control Room and AV Solutions is the only known company in South Africa to offer refurbishment as an alternative to replacement, at a fraction of the price of a new unit. The refurbishment is specific to the internal components of the microphone and workmanship is guaranteed for a full six months. Click here to contact us.


Display resolution explained

What is meant by screen resolution?

Very simply stated, an image or picture on a display screen is made up of a number of dots called pixels. These pixels run left to right (horizontal) and top to bottom (vertical). The more pixels on a screen, the higher the definition of the image. For example, where a TV screen with a resolution of 640 pixels by 480 pixels (640 x 480) displays a picture of a flower, that picture would look a little pixelated or “fuzzy” when compared to another screen of the same physical size but having a resolution of 1920 x 1080 displaying the same flower. The second screen, even though it is of the same physical size, has more dots making up its image, and thus, the image looks much better or is said to be of a better definition.

The chart below shows the relationship between screen resolution and aspect ratio in a simple to understand manner.

But what do all the fancy terms and numbers mean?

Aspect ratio – This describes the shape of the image. It is the ratio between the width and the height of the image. The two common aspect ratios are 4:3 commonly referred to as “letterbox” and 16:9 referred to as “wide-screen”. The 4:3 image looks more square when compared to the 16:9 image which is rectangular.

Full HD – Full high-definition refers to a HDTV (high-definition TV) mode characterised by 1920 x 1080 pixels. This is different from 720p HD which is characterised by 1280 x 720 pixels.

VGA – Or video graphics array was a popular display standard introduced in 1987 by IBM. It had a resolution of 640 x 480 pixels. VGA was later replaced by SVGA which stood for super graphics array and was characterised by a resolution of 800 x 600 pixels and later extended to the very popular 1024 x 768 resolution while keeping the same D-sub connector.

DVI – Or digital visual interface is an interface, characterised by a rectangular connector, designed to transmit uncompressed digital video information between a source and display. DVI supports multiple modes – DVI-A (analog), DVI-D (digital) and DVI-I (integrated) which is a combination of digital and analog. The DVI specification is compatible with the VGA interface. Although DVI is primarily associated with computers, it is also used in consumer displays and DVD players.

HDMI – Or high-definition multimedia interface is an interface used to transmit both uncompressed digital video and audio over a single interface, from a source to a display device.

The modern control room

What exactly is a modern control room?

A control room or operations center is a room serving as the central hub from where a facility or service can be monitored and controlled.

These control rooms usually consists of a number of operator workstations and a large view screen or video-wall which is visible from all areas within the room. Information or processes are monitored and controlled by the individual operators and shared to the large display screen to allow for collaboration.

Some examples of control rooms

Security control room – This type of control room is usually used to monitor security camera feeds and alarms and may be staffed by the police, military or private security companies. The operators typically communicate information to the response teams in the field or co-ordinate special operations.

Process control – Power plants and mines have a number of automated processes which run 24 hours a day. The machinery & processes need to be monitored  constantly for safety and operational reasons. This is usually achieved by control room operators viewing and monitoring these processes from a central location being the control room from where the equipment can be controlled remotely by SCADA software.

Call centers –  may utilise a control room to monitor incoming and outgoing calls. The statistics may be displayed on a large screen for the purpose of enhancing the customer service experience.

 Design considerations

A modern control room should be designed with ergonomics, aesthetics and functionality in mind. These include lighting, space, acoustics and the health and safety of the operators.

The equipment needs to be reliable, with built-in redundancy as many control rooms operate 24 hours a day and equipment failure could negatively impact the operation or even cause harm.

The large format displays or video-walls need to be easy on the eyes and appropriately positioned to allow for maximum visibility. Rear projection LED lit DLP screens such as the ones manufactured by Barco are considered the most reliable as they are designed for true 24/7 operation.
