![]() Thus, the number of transmittable signals is less than the number of contacts. The sleeve is usually a common ground reference voltage or return current for signals in the tip and any rings. Since phone connectors have many uses, it is common to simply name the connector according its number of rings: Between the tip and sleeve are 0 to 3 ring contacts. Contacts are insulated from each other by a band of non-conductive material. The sleeve contact is nearest the (conductive or insulated) handle. The tip contact is indented with a groove. A male connector (a plug), is mated into a female connector (a socket), though other terminology is used. Invented in the late 19th century for tele phone switchboards, the phone connector remains in use for interfacing wired audio equipment, such as head phones, speakers, micro phones, mixing consoles, and electronic musical instruments (e.g. TS and TRS plugs of different sizesĪ phone connector is a family of cylindrically-shaped electrical connectors primarily for analog audio signals. When not mated, this spring instead connects to the flat switch contact for detecting a plug. The plug's grooved tip is held firmly by the socket's spring tip contact.

It features signal retiming for a perfectly synced audio track, as well as voltage overload protection to prevent damage from unreliable power sources.This article needs additional citations for verification. The switch is compatible with various audio formats including DTS, Dolby AC3 and LPCM2. Being a powered unit, this switch doesn't degrade the quality of your digital audio running through it. Alternatively, use the USB cable (included) with a USB power adaptor (sold separately) to plug into a mains power outlet. Note that the device with the USB port sometimes needs to be switched on for this to work. We include a USB cable which you can simply plug into a USB port (eg: on a TV or gaming console) to provide the necessary power. This can be very useful for creating a multi-room system.īeing an active/amplified unit, it requires a power source. The built-in amplification also enables output distance of up to 40 metres from the output (dependent on your equipment and your cable). ![]() This switch also includes an IR receiver on a short lead, so you can hide the unit away behind your AV equipment or in a cabinet, and still be able to control it with ease! The included IR remote makes it a breeze to change which source device is operating through the switch. Amplified signal means no loss of quality Supports signal retiming for perfectly synced audio Overload Protection prevents damage by excess voltage Supports various audio formats & sample rates (DTS, Dolby AC3, LPCM2, up to 192KHz) Perfect for when your receiver or TV doesn't have enough optical inputs for all your devices! Easily switch between inputs with the included IR remote! The LED on the side of the switch will indicate which input is being used! This switch is as easy to use as it is handy! This 2-Way Optical Switch allows the connection of 2 digital audio sources to a single input on a device.
