Linn LK85 - Manual (Page 11)

The LK85/140 is direct-coupled and servo-controlled to produce
the clearest sound and the toroidal transformer is fully shielded to
prevent hum when the amplifier is stacked with other products.
The LK85/140 provides two input sockets to make it easy to daisy
chain multi-amplifier systems, allowing you to boost the output
power of your system, or take advantage or bi-amping and
tri-amping.
Loudspeakers can be bi-wired to the LK85/140 by the use of the
two loudspeaker sockets to obtain even higher sound quality.
Bi-wiring involves making separate connections to the treble and
midrange/bass units on a loudspeaker. Keeping the treble and
midrange/bass signals separate improves the performance of the
loudspeakers by reducing the coupling between the signals.
