The typical termination standard between Linn products are:



Input sensitivity: Selectable: 1 / 2 / 4 Vrms

Typical Input impedance: typically 10 kΩ

Analogue Output: 2 Vrms

Typical Output Impedance: 300 Ω

RCA Output Coupling: Transformer - Klimax DS/1 onwards and all Klimax DSM

Direct - all other products



Input sensitivity: Selectable: 2 / 4 / 8 Vrms

Typical Input impedance: 7.8kΩ

XLR Coupling: Direct (some Klimax products have the option of Transformer or Direct)

Analogue Output: 4 Vrms

Typical Output Impedance: 600 Ω
XLR Output Coupling: Direct - Majik/Akurate/Selekt/Klimax DSM (2021 variant)

Transformer - Klimax up to 2018 variant.

Audio Transformer

The audio transformer is there to electrically either isolate the Klimax DSM from the connected amplifier or from the connected source.
The transformer can help to eliminate ground noise in some situations, such as mains electrical without a mains earth.
Some people prefer the sound with this transformer enabled, some with it disabled, so we have provided the option.


Linn DS/DSM/Hub Output configuration: Fixxed level, there is NO volume control even in Post Eq mode.
Linn DS/DSM/Hub Input configuration: 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz : 16bit and 24bit streams


Input voltage 0.3V (when terminated with 75Ω )

Input impedance: 75Ω


Min Input voltage 0.5V rms (when terminated with 75Ω )

Input impedance: 75Ω

Exakt Cables

ALL FOUR pairs of the cables are used in the Exakt-Link cable. This is NOT an ethernet transport cable but an Exakt transport cable. These pairs are used to transmit the audio data, power triggers and a master timing control to ensure that the audio from all channels are in perfect sync.

The Exakt-link has been designed to operate with the CAT-5 cable electrical specifications for signal timings. There have been NO changes to this design for any other CAT cable standards. (updated 2019)

We recommend using the 100Base-T4 / 568B ethernet cable pairing
Exakt Link uses readily available network cables:
  • CAT 5/5e UTP/FTP
  • CAT 6/6a UTP/FTP
Note: There is no change in the audio performance of the Exakt Link between Cat 5 or Cat 6 Cables.

Cat-7 and Cat-8 cables may not work well with an Exakt system. For a trouble-free, reliable, high performance installation, we recommend use of Cat 5 or Cat 6.

Typical Ethernet 100Base-T length restrictions guide:

Patch cable < 30M
Solid core cable < 100M

EXAKT-LINK CANNOT be used with:

  • Ethernet Network Routers,
  • Ethernet Network Switches,
  • Ethernet Isolators,
  • Ethernet conditioners,
  • HomePlugs/Ethernet-over-Mains devices
  • WLAN bridges etc

Exakt-Link can ONLY be a CAT5/6 cable from Exakt socket to Exakt socket

EXAKT LINK terminations

  • The cables are paired up using OUT > IN style connections.
  • Any Linn product with these sockets can be linked together. This means you can link a Klimax DS/2 to a Majik ExaktBox-I and have a fully working Exakt system
