February 22, 2024 – Computer Audio Design (CAD) firmly believes that reducing unwanted high frequency noise in a hi-fi system audibly improves the system’s sound quality. To that end, the company has pioneered a portfolio of highly effective solutions to the problem, and now adds the new Ethernet Control, designed to enable a significant advancement of the musical performance of streaming-based and file-replay systems.
Underpinning the design of the new Ethernet Control is CAD’s 14 years’ experience in developing their multi-award winning 1543 DAC, CAD Audio Transport, USB Cables, USB Control and Ground Control products, along with company founder Scott Berry’s in-depth knowledge of computer-based audio as a whole.
The Ethernet Control is engineered to reduce unwanted high frequency noise on the Ethernet network connection in audio and video equipment. It will deliver audible results with both streaming services (Spotify, TIDAL, Qobuz, etc) and with locally stored music files. Appealingly, the device is small, unobtrusive and simple to use.
The Ethernet Control effectively addresses noise on the differential Ethernet signals, and additionally on the signal ground and the Ethernet interface, of your networked audio device. This is achieved by way of custom CAD noise reduction technology borrowed from the company’s successful Ground Controls and USB Control. CAD’s own proprietary transformers deliver galvanic isolation along with greater reduction of noise over a larger frequency spectrum than standard Ethernet transformers. In addition, a directly connected custom-built, ultra-thick gold-plated RJ45 plug minimizes impedance between the server/computer or DAC/streamer and the noise reduction technology inside the Ethernet Control. The unit’s non-conductive outer acrylic case is designed to offer an attractive compact enclosure with vibration dampening.
The Ethernet Control is intended for use with audio source components such as servers, computers, streamers and DACs, and also with amplifiers and other analogue components with RJ45 connections for service, control or configuration.
It could not be more simple to add to your system: just plug your network Ethernet cable into the RJ45 socket of the Ethernet Control, and then insert the Ethernet Control RJ45 plug into your server/computer or DAC/streamer.
CAD recommends placing the Ethernet Control at the final termination of the Ethernet cable as it enters your audio system. However, additional units can also be located at multiple connection points on the network to give further sound quality improvement. For example, try a second Ethernet Control on the input or output of a network switch, router and/or server/computer.
The Ethernet Control is hand-assembled and individually tested in the UK.
