Audio and Video Accesories

The need for high quality audio and video, either locally or from remote sites, makes corporations seek technology that facilitate this work. Achieving the reproduction of professional video and audio, requires technological infrastructure designed according to every project’s needs. Our company conducts uprisings on site, makes blueprints, and on this basis, creates customized solutions where it is important to choose brands that will perform better in certain sites.

Accessories such as tabletop interfaces with connectors of different kinds, make it possible for a table in aBoardroom to be clean with hidden connections and cables. Other common accessories are adapters, converters, signal amplifiers or climbers needed to create a clear diversity of signals and sources in an audiovisual installation. Signal extenders are widely used to achieve long runs using UTP cables between the linked devices.

​Service Boxes

The service boxes work as interfaces that have the necessary connectors and / or cables to connect our audiovisual devices in a room. For these boxes there are different systems such as tilt'n plug or pop'n plug and have different arrangements and connections. Some boxes are already pre-designed and others can be customized with: power, USB, internet, HDMI, VGA, DVI, video, audio, telephone, etc.

With Grupo Covix you can find useful and aesthetic Service Boxes to place on tables, podiums, consoles, desks, floor-mounted, boxes to hide / store multimedia cables, etc..

​Cables & Connectors

There are different types of cables and the choice of each of them depends on the signal that you want to transmit from one point to another, from a source to a point of deployment, output or receiver. Existing distances, equipment, technology, bandwidth, signals, configurations, racks, etc., should be taken into account before making a choice.

Cables and connectors are the cornerstone of a good installation, giving them the importance they deserve will result in excellent performance of all equipment and solutions. There are different types of cables and the choice of each will depend on what you want to achieve. Before choosing one, existing distances, equipment, technology, bandwidth, signals, settings, racks, etc. should be taken into account.


Extenders are devices that help us to carry a signal to further points without losing quality in it. Let's take as an example a digital signal that must be transmitted over an HDMI cable from 30 meters away. HDMI cables have large connectors that are difficult to pass through ductwork, and are fragile and their signal begins to decline after a few meters. In this case the solution is to use video extenders, a transmitter is placed where we have the source and a receiver where the end point is located. Both extenders will be connected by UTP cable, which will be in charge of transmitting the signal. The UTP cable is easy to handle, runs easily through ductwork and supports long runs, and its connectors (RJ45) are small, and can be "punched", unlike HDMI connectors. For longer distances fiber optic extenders can be used instead of UTP. The quality of the wiring will determine the distance the signal will travel.

Since the transmitter extender (TX) amplifies the signal, it must be supplied with electrical current. Grupo Covix implements in addition to extenders, all the necessary accessories to make any transmission problem transparent to the user, and to ensure that the signals are observed at the end point with the same quality as those originated from their source.


A switcher, also called a matrix router, is a device that routes input signals to certain outputs. It is the most economical and traditional way to send fonts to one or more screens. There are switches of all video formats, for example there are HDMI, DVI, VGA, etc., but not only that, there are also switches for audio and other types of content. Multiple fonts can reach multiple screens but with the limitation that the switching is one by one, that is, only one font goes to each screen. With a switcher you cannot splice fonts or make a PiP (Picture in Picture), nor can you send more than one font per screen at a time.

A switcher is the way to save costs when you can't invest in a Video Processor, which has more flexibility and more versatility in its image handling.
