AV Adapters

A coupler joins two leads with the same connector, while an adaptor turns one connector type into another. The AV:Link 766.299UK coaxial coupler joins two aerial leads, for example, and the 775.421UK adaptor turns a coaxial TV plug into an F socket. Neither converts the signal; analogue VGA to HDMI needs a powered converter such as the 122.423UK kit.

Yes. The AV:Link 122.425UK carries digital audio and video from a DisplayPort output to an HDMI socket at a maximum resolution of 3840×2160 (4K UHD). It is a short 13.5 cm adaptor lead with gold plated connections, so an additional HDMI cable is needed to reach the TV or monitor.

Use a converter, because VGA is analogue and HDMI is digital. The AV:Link 122.423UK kit converts a VGA plug and 3.5mm audio to an HDMI socket at Full HD 1080p, powered from its micro USB cable, and an additional HDMI cable completes the link. For the reverse, the 122.437UK adapts an HDMI plug to a VGA socket.

Yes, with the AV:Link 122.413UK, which adapts an HDMI socket to a micro HDMI plug so a standard HDMI cable can connect to a Raspberry Pi, tablet, camera or camcorder with a micro HDMI port. It has gold plated connections and needs no software or drivers to work.

Use the AV:Link 122.410UK switchable adaptor. It connects RCA or S-Video outputs to the SCART input on a TV, or SCART outputs to RCA and S-Video recorders and displays, with a switch to select input or output. It suits older equipment such as set top boxes, VCRs and camcorders.

A 3.5mm socket to 6.3mm plug adaptor, such as the QTX 757.873UK, which converts a 3.5mm stereo jack socket into a 6.3mm stereo jack plug for stereo headphones. For the opposite case, the 757.882UK nickel and 757.888UK gold adaptors take a 6.3mm stereo plug to a 3.5mm stereo socket, in packs of 10.

A stereo jack carries left and right channels, while a mono jack carries one. QTX mono adaptors such as the 756.019UK suit unbalanced mono signals, and stereo adaptors such as the 758.361UK coupler carry unbalanced stereo or balanced mono. The 759.185UK takes a stereo plug to a mono socket, summing the signal to mono.

Yes. The QTX 764.343UK connects an RCA phono socket to a 3-pin XLR male, and the 763.946UK converts a 6.3mm mono jack plug to an XLR male. QTX describes these two for unbalanced audio signals, so they adapt the connector without balancing the line.

Use the AV:Link 773.498UK, which converts a BNC plug to an RCA phono socket and is sold in packs of 5. It converts professional composite video to a domestic connection. To join two BNC leads instead, the 769.042UK is a 50 ohm back-to-back BNC coupler, in packs of 10, for video signals in CCTV systems.

Yes. The AV:Link 113.538UK ADSL filter adaptor converts a BT431A plug to an RJ14 socket for broadband and a filtered BT431A socket for the telephone, and up to 4 filters can be used on one line. The 113.544UK splits an RJ11 plug to 2 RJ11 sockets and suits USA and Southern Ireland outlets.
