Installation & Operation
3-K DRIVER ARRAYREMOVAL AND REPLACEMENT
The 3-K driver array can be removed by unscrewing the
seven M4 retaining screws and carefully withdrawing the
unit directly away from the baffle until the built-in
connector at the back of the unit disengages.
Replacement is a reversal of the above procedure, taking
care to tighten the retaining screws no more than is
necessary to hold the driver array firmly in position (set
torque driver to 200 cNm if used).
FUSE REPLACEMENT
The fuse is a time delay type. Always replace with a fuse
of this type and rating (see the Technical Specification
section). If the fuse repeatedly blows within a short time of
being replaced, please contact Linn for advice.

without the need for special tools or specialist personnel.
The replacement procedures are outlined below but fuller

on request.
