Formed in 1983, SY has been at the forefront of electronics design and development, specialising in microprocessor systems, switchers, HDMI & VGA splitters and extenders, alongside an array of keypad controllers, all designed to complement the AV industry and AV integrators.

SY have gained an unrivalled reputation for technical innovation, product reliability and technical support for system integration. By taking a consultative and proactive approach, SY assists companies to utilise their budget intelligently, ensuring solutions are viable and effective.

Operating from their Head Office in Manchester, UK, SY also has a regional office in Luton Bedfordshire, which incorporates a fully equipped demonstration and training facility.


SY’s Controllers provide a complete range of simple to use and easy to install keypads for media displays, projectors and associated equipment control. They feature tri-colour LEDs, soft touch buttons, a host of device connection ports such as bi-directional serial or infra-red ports, ethernet, input detection ports, output ports for relay control, USB configuration and low voltage power. ‘V’ models also feature a rotary volume control with level indication derived directly from the device being controlled.

Each button can be programmed to perform multiple functions and is the ideal solution to replace multiple handsets, whilst providing a permanent location for the point of control. This saves lost or misplaced handsets, so there’s no more running out of batteries, just when you need the system to work.

The SY Device Suite software provides a powerful yet easy-to-use tool for configuring the SY-KP Series Controllers to respond just the way you want. The SY Keypad Controllers also fit in standard UK and European size back boxes and are supplied in either a modern smooth anodised finish, black or a smooth matt white finish, which are resistant to finger marks, yet easily wiped clean.


SY supply a range of presentation, multi-format and matrix switchers to address many AV switching, routing and processing applications. Whether you’re designing a complex dividable space where AV signals must be dedicated to different zones with the flexibility to route identical or separate signals to the displays, or if you’re designing a simple classroom for HDMI and legacy analogue sources, where signals must travel a long distance, SY’s Switcher solutions provide flexible control options and allow for streamline installation for these applications and more.

SY’s range includes:

  • HDMI switchers with RS232 control.
  • Compact 4K multi-format switchers with HDMI, VGA & DisplayPort inputs along with in-built HDBT Transmitters.
  • Single and dual zone distribution amps.
  • 4K 18Gbps multi-format presentation switchers with built in scaling.
