Audio connections
Depending on the type of signal and intended use, various connections are required.
i
Speaker connections:
Depending on the amplifier power and cable diameter, different
speaker connections are available:
Speaker connectors
• Positive contact
ı Negative contact
Observe these contacts when connecting the
speakers
Speaker jack/connector
Compact plug-in connector for speaker
connections with low to medium-ranged
power (max. 50V – corresponds to 312W on
8 Ohm)
Speaker terminal
Terminal connections for directly connecting
the speaker cables to small to mid-sized cable
diameters.
Red: Positive terminal
Black: Negative terminal
Banana plugs
Banana jack
Speaker connections for mid to high-range
power
Analogue NF signal connections:
Din socket
3-pin (mono) or 5-pin (stereo)
Connection for NF audio signals.
The signals are routed using separate
contacts for recording and playback.
A 5-pin Din jack equipped with a special
contact assignment (cube) was used as a
headphone output in the past.
Digital NF signal connections:
ODT/Toslink Plug
ODT/Toslink Socket
Connection for digital audio signals using
optical fibre cables. The transmission of
multi-channel surround sound only requires
one connection, while the transmission of
analogue sound requires 5 cinch connections
or more cable. Since the signals are transmitted
optically, the devices are electrically
decoupled.
AV Cables
XLR plug
XLR connector
Robust multi-pole connections with automatic
locking mechanism. Used by professional
musicians as speakers, microphones and
connecting cables and in home movie theatres.
They are used for symmetrical and asymmetrical,
analogue or digital audio signals.
Normally, equipped with extra thick shielding
as a result of the shielded individual cables.
Analogue NF signal connections:
RCA (phono) plug
RCA (phono) connector
2-pin plug-in connection:
The inner conductor is the signal line
The exterior conductor is the shielding. The
most common connection for audio signals.
Colour marking for the various signals
in surround systems:
Red: Right, front right
White: Left, front left
Blue: Left surround LS
Grey: Right surround LS
Green: Centre LS
Violet: Subwoofer
Brown: Rear left surround
Sand: Rear right surround
2.5 mm, 3.5 mm, 6.3 mm universal
Jack plug Jack socket
2-pin (mono) or 3-pin (stereo)
Connection for audio signals. Normally for
headphones or microphone signals
ODT 3.5 mm plug; MiniToslink
Similar to ODT with a smaller plug design.
Using a special jack, optical or electrical
signals can be transmitted with portable
devices, for example, MP3 players. A 3.5 mm
jack coupler can then be used as an electrical
socket via a 3.5 mm universal jack plug. If a
3.5 mm ODT is connected to an ODT cable, the
optical sensor in the device is used.
RCA (phono) digital/RCA (phono) coaxial
Connection for digital audio signals via a 75 ohm
coaxial cable. Similar to the ODT, it’s also multichannel
capable.
Marking: Orange
FireWire/IEEE 1394i/iLink/lynx* socket
4-, 6- or 9-pin models
Digital interface for quickly transmitting digital
audio data to a PC. For example, with MP3
players or Hi-MD walkmans. Data transfer rate
with up to 400 Mbit/s.
* diverse names according to the manufacturer
USB interface
Digital interface for quickly transmitting digital
video data to or from a PC. For example, with
MP3 players or Hi-MD walkmans.
Tip: digital signal connection, DVD player with AV receiver
Analogue RCA (phono) connections should also always be used with digital
optical/coaxial connections, since they are necessary to record an analogue
sound on tape. If, for example, a CD is played in a DVD player, the CD can be
heard, but not recorded on tape because the receiver does not convert the
digital signals and thus transmits them as such to the analogue connections.
