Speaker/Power Amplifier connections

Speaker terminals


The binding post terminals can be used as sockets for the connection of 4 mm banana plugs or can be used as binding posts for the connection of bare wires or spade terminated cables by loosening the outer section of the binding post (do not attempt to completely remove this outer section), inserting the cable or terminal and re-tightening the binding post to clamp it in place. Ensure that all the binding posts are tight.

We recommend using Class 2 wiring of at least 16AWG.

DOUBLE CHECK the wiring from the Exaktbox-I to speaker terminals!
If there are any mis-wires or wrong speaker definintions in the Exaktbox, you may blow the speaker drive units, so take care.

If this is the first connection use the standard Aktiv test scenario.

  1. Put the Linn DS/DSM into Sleep mode to power down the ExaktBox-I.
  2. Disconnect any Exaktbox-I to speakers connections
  3. Set to a low volume value, e.g 40-50
  4. Do the following tests 5,6,7,8 starting with the Bass connections, then Midrange, then tweeter and finally super tweeter in that order.
  5. Connect respective (Bass or Mid or tweeter or super-tweeter) Exaktbox-I connection to the Bass connection (Bass or Mid or tweeter or super-tweeter) of the speaker.
  6. Bring the Linn DS/DSM out of Sleep mode and play some Music. Check that you are only getting (Bass or Mid or tweeter ot super-tweeter) audio from that speaker drive unit.
  7. Stop the Music playing and put the Linn DS/DSM into Sleep mode
  8. Leave this cable connected go to Step4 and connect the next speaker drive unit in the list.

If you change speaker or variant, this may also change the Exaktbox-I terminations so DOUBLE CHECK
