Linn 343 Exakt FAQ's

Why use different types of amplifier in 343 Integrated Exakt?

The design of each amplifier in 343 is tailored to the requirements of its associated drive unit.

The 343 Array is driven by a Linn designed Class-AB amplifiers with Adaptive Bias Control. This gives the best performance over the frequency range of these drive units. Even within the 343 array, the single-ended amplifiers are tailored to each drive unit. The tweeter amplifier is further ‘tuned’ to ensure very low distortion up to the very highest audio frequencies, improving the signal-to-noise level by around 15 dB compared to the prior art.

The bass system uses the new Linn Power DAC architecture to achieve low distortion at high power whilst also being very efficient. This allows the BASS system to play deeper and louder for longer.

What is Adaptive Bias Control

Adaptive Bias Control technology is the control of the ideal bias current for all the amplifier output transistors. This is established dynamically and in real-time by measuring, sampling and digitising the current measurement, then using a closed loop to set the output bias voltage through a DAC and novel analogue floating bias circuit.

A digital control loop then implements and persistently adjusts this optimum bias current for the transistors; negating crossover distortion at any temperature – regardless of volume or demanding dynamic changes in music – for the entirety of the amp’s life.

What are the integrated amplifier ratings?

The Linn Power DAC is easily capable of delivering 500 Watts into a four ohm load.

The Adaptive Bias Control amplifiers for the upper bass, midrange, and tweeter can each deliver 150 Watts into a four ohm load.
