About the LK140

The Linn LK140 is a rugged, high-output stereo power amplifier designed for purity of sound and ease of use. It delivers 140 watts per channel into 4 ohms and 95 watts per channel into 8 ohms, making it suitable for average to larger rooms and multi-amp setups such as bi-amping and tri-amping. The amplifier features automatic power-up when detecting an audio signal and standby mode to minimize power consumption. It includes full protection against power overload and overheating, automatically shutting down and restarting as needed. The LK140 has a compact, durable design with dimensions of approximately 320mm x 325mm x 80mm (12.6" x 12.8" x 3.15") and weighs about 7 kg (15.4 lbs). It offers advanced control features, upgradeability, and compatibility with Linn's LK design. Inputs include a single line input (L/R) and AC power input; outputs include four speaker outputs optimized for bi-wiring and tri-wiring, plus line outputs for further amplification. The frequency response ranges from 10Hz to 70kHz, with a gain of 28.6 dB and input sensitivity of 0.87V. The amplifier consumes up to 570 watts maximum power and has a standby power consumption under 5 watts. It is made in Scotland and is highly regarded for pitch-accurate sound reproduction and reliability.
