For current Hi-Fi devices, the RCA plug is the usual connection for analog signals. The plugs are usually uniformly color-coded depending on the area of application.
The most commonly used variant has two connections for a stereo connection:
Depending on the area of application, there is also an additional connection for video signals:
Especially with adapters for DIN plugs, four connections are often also used, since the DIN plugs serve as input and output at the same time:
Help to remember: "colorless" connections on the left, "colorful" connections on the right, w white/red for Wi playback
The round, mostly 5- (stereo) or 3-pin (mono), DIN connections can be found in the Hi-Fi range almost only on older devices. Here, a single plug is used for recording and playback. A connection to Hi-Fi devices with RCA connectors is possible with the help of an adapter, the usual color coding is explained with the RCA connectors.
In addition, speaker connections are often found on older devices (up to the end of the 1970s) according to DIN 41529 ("dash-dot plug"):
The matching plugs are available in specialist shops and can be screwed or soldered to the speaker cables.
Less common are the so-called cube plugs, DIN plugs, which were used to connect headphones. The name is derived from the arrangement of the pins in the connector in the form of the number five on a game cube. With the help of an adapter, these plugs can be used on the jack sockets that are common today.
The 3.5 and 6.3 mm jack plugs are usually used in the home audio sector to connect headphones, whereby the smaller version (mini jack) is usually used in mobile devices such as MP3 players. Less often there is also a variant with a 2.5 mm plug.
3.5mm jacks are also often found as a line output on sound cards. With the help of an adapter, it is possible to connect to an RCA connector, for example, to connect the PC to an amplifier.
In the home audio sector, a digital transmission usually takes place on the basis of the S/P-DIF specification. Three connectors are common here:
The conversion between optical/electrical connection is easily possible by means of an adapter.
Many sound cards now offer digital outputs, so that the D/ A conversion is taken over by the amplifier/receiver or an external D/ A converter. Optical connections also have the advantage that the occurrence of hum loops is prevented.
Clamping and screw connections are widely used in the speaker area, to which the strand of the speaker cable is directly fixed without a plug. It should be avoided to tin the cable end. In the case of the usual screw connections, cable lugs can often also be used.
Screw connections are often also combined with sockets for banana plugs. These plugs with a diameter of 4 mm are mainly designed for use in electrical laboratories and provide a stable connection.
Caution is advised, as banana plugs can also be plugged into Schuko sockets and this can lead to electrical accidents if used improperly.
On older devices (up to the end of the 1970s), speaker connections according to DIN 41529 ("dash-dot plugs") are often found:
The matching plugs are available in specialist shops and can be screwed or soldered to the speaker cables.
Speakon is a connector for loudspeakers developed by Neutrik. It is characterized by its robustness and the possibility of a secure locking. Speakon connectors with 2, 4 and 8 poles are available.
XLR connections are mainly used in the professional field (recording studios), for connecting microphones and speakers. But more and more often they can also be found on high-quality Hi-Fi devices, where they are used for the symmetrical transmission of analog signals. With the help of an adapter, a connection to RCA jacks is possible.
Different cables are used to connect microphones/Hi-Fi devices and loudspeakers. In contrast to the microphone cables, the speaker cables are unshielded and asymmetrically wired.
HDMI is an interface developed in 2003 for the digital transmission of audio and video data. In the current version 1.3, the up to 7.1 dts-HD Master Audio, Dolby True-HD and Dolby Digital Plus (lossy) sound formats are also supported. Audio DVDs and SAC D are also supported and transmitted via HDMI from version 1.2a onwards. Currently there are DVD players and Blu-ray players that have HDMI 1.0a - HDMI 1.3a . Depending on the specification and equipment, not all players and recorders output the same sound formats. The new HD sound formats are currently only offered on Blu-ray Dics due to the high data capacity.
