LINN LK140 The LK85/140 and music The LK85 and LK140 are rugged high output amplifiers designed for ease of use and purity of sound. Y ou can build exactly the system you want, using one or more LK85/140 amplifiers. The LK85 gives 85W per channel into 4 1 , or 62W per channel into 8 1 , and so is ideal for most average-sized rooms. Alternatively , [...]

The LK85/140 is dir ect-coupled and servo-controlled to pr oduce the clearest sound and the tor oidal transformer is fully shielded to prevent hum when the amplifier is stacked with other pr oducts. The LK85/140 pr ovides two input sockets to make it easy to daisy chain multi-amplifier systems, allowing you to boost the output power of your system,[...]

For more performance, you can use two or thr ee LK85/140s to bi-amp or tri-amp to the loudspeakers, each amplifier driving the bass, midrange, and tr eble signals separately . When bi-amping or tri-amping the highest possible performance can be obtained by removing the passive cr ossover units fr om the loudspeaker and fitting active cr ossover mod[...]

Setting up the LK85/140 This chapter explains how to unpack your Linn LK85/140 Ster eo Power Amplifier , and how to install it with your other hi-fi components. Unpacking Before connecting the LK85/140 to the mains supply , you should check the following: • that everything is in the box • that the correct voltage has been selected • that the [...]

Replacing the fuse T o replace the fuse, first identify the corr ect fuse for your local voltage. This should be: • 3.15A anti-surge for 230V • 6.3A anti-surge for 115V • 6.3A anti-surge for 100V (Japanese version). Pull open the fuse drawer at the bottom of the mains inlet, insert the fuse in the rear compartment, and close the drawer . Eart[...]

Connecting The following diagram shows the connections for the r ear panel of the LK85/140: Connecting the mains supply Connect the LK85/140 to a mains supply using the mains cor d supplied. Note that the LK85/140 should be switched of f before connecting or disconnecting the plug on the r ear panel, or you may generate surges which could damage ot[...]

Connecting the speakers The LK85/140 comes equipped with two pairs of speaker output sockets to allow bi-wiring. Alternatively , auxiliary speakers may be connected. Oper ation T o turn on the LK85/140 amplifier , press the power switch on the front panel. Signal detector sensitivity The LK85/140 uses signal sense circuitry to detect the pr esence [...]

By-passing the signal detector Depending on its configuration, the LK85/140 will r emain on standby for 10 or 20 minutes after an input signal has been removed. Y ou can override this facility by fitting an internal link which for ces the amplifier to remain on as long as the mains power is connected. Please consult your Linn r etailer for further [...]
