The LK140 and Music

The LK140 is a rugged high output amplifies designed for ease of use and purity of sound.

You can build exactly the system you want, using one or more LK140 amplifiers. The LK140 gives 140W per channel into 4Ω, or 95W per channel into 8Ω.

The LK140 comes in a durable compact case built to last, and easy to stack on other Linn products. The amplifier has been designed to power up automatically when it detects the presence of an audio signal and power down into standby mode when there is no signal. This enables it to be left on with minimum power consumption. An indicator light on the front panel remains red when the amplifier is in standby and green when it is powered up, telling you at a glance the operational status of the amplifier.

The LK140 comes with full protection against power overload and overheating, automatically shutting down to prevent damage to itself or other Linn equipment, and powering back up when it is safe to do so.

The LK140 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 LK140 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 LK140 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.

For more performance, you can use two or three LK140s to bi-amp or tri-amp to the loudspeakers, each amplifier 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 LK140 to accurately divide the signal into the appropriate frequency bands. This is known as active playback.

The LK140 is designed to be easy to convert to active playback. A complete range of stereo active crossover modules is available for all current Linn loudspeakers. Your retailer can fit these and make the necessary changes to your loudspeakers to transform your system to fully active.
