Doufer
A Knekt device. Known in some manuals as the ‘wee doufer’ (‘wee’ meaning small for any persons unfamiliar
with the Scottish vernacular) - a small interface board (about 3cm square, with a 9-way d-type computer plug
at one end and an RJ45 socket at the other). Connects the input / output Port of the computer to the RJ45
cable connections which go to the Knekt system. Used to download software revision to the RCUs in a Knekt
system
Download
A universal term for the transfer of software from a Computer to some other device. The computer
Downloads to the device which receives an ‘Upload’, so Download and Upload happen simultaneously -
this may sound complicated but it is not - although both terms refer to the same event (the transfer of
software), what it is called depends on whether the software is being sent or received. The sender
Downloads, the recipient is Uploaded. More specifically, in a Knekt system, it refers to the transfer of
software from the PC to the RCU. The AV5103 also receives Downloads for new software transfers.
Driver
Linn Knekt Line Driver - A device, used in Knekt systems which distributes audio from Source products in a
Main room to one or more Secondary rooms, allows the Secondary rooms to control the source products and
also passes ‘status’ feedback (for Linn products only) to those rooms. (ie on the RCU there, you can see
things like radio frequency on a tuner, track playing on a CD player etc). Available in ‘Standalone’ (Knekt-D)
and ‘Sneaky’ (Sneaky-D) versions.
Dry Joint or Dry Solder Joint
A solder joint which is not making good contact is known as a Dry Joint – very often this type of joint will
make intermittent contact and this makes the problem difficult to detect during testing etc. Several things can
cause a dry joint – e.g. the joint may have been made with insufficient solder to hold the joint securely and
the solder breaks, there may be a problem where the solder did not flow properly and is only making contact
with either the component leg or the track on the board (requires to make good & secure contact with both),
or perhaps no solder was applied at all.
DSP
Short for Digital Signal Processing. With reference to AV systems, tt does just as the name suggests -
processes the digital signal - takes the surround sound digital signal (eg AC-3) and processes it to create the
correct output for each speaker (front, centre, rear, sub).
DTS
Short for ‘Digital Theatre Systems’ - A Surround Sound mode. For more information, see the DTS website –

Dummy Load
A device, which we at Linn use to take the place of a pair of speakers for the purpose of testing and checking
power amps. It is, quite simply one or two resistors per channel (which add up to 4ohms or 8ohms) clamped
to a large heatsink
