Page 8: Introduction
To do that, you need to know exactly how to get the best out of your LK240 and that is what this manual is all about. In the next few pages you will find out everything you need to know about how to set up the LK240, and how to use it to get the best possible results. -

This enables it to be left on with minimum power consumption. An indicator light on the front panel remains red when the LK240 is in standby and green when it is powered up, telling you at a glance the operational status of the LK240. - Page 10 The LK240 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, or tri-wired to the LK240 by the use of the four loudspeaker sockets to obtain even higher sound quality.
- Page 11 To further enhance performance, you can use two or three LK240s to bi-amp or tri-amp to the loudspeakers, each LK240 driving the bass, midrange, and treble signals separately. When bi-amping or tri-amping the highest possible performance can be obtained by removing the passive crossover units from the loudspeaker and fitting active crossover modules to the LK240 to accurately divide the signal into the appropriate frequency bands.

Setting up the LK240 This chapter explains how to unpack your Linn LK240 Single Speaker Power Amplifier, and how to install it with your other hi-fi components. Unpacking Before connecting the LK240 to the mains supply, you should check the following: •... - Page 13 Selecting the correct voltage The LK240 is factory-set for a 230 volts mains supply and must not be connected to a mains supply before it is adjusted for your local voltage. To do this, slide the red voltage switch at the back of the unit until the appropriate voltage is displayed.
