Introduction

Linn 2250

The Linn 2250 is a high power two-channel amplifier designed for use in multi- amplifier audio and video systems. It exemplifies Linn’s unremitting commitment to exploiting the latest technology in order to produce ever better sounding products. The unit’s features include Linn’s switch mode power supply (see below), automatic signal sensing, bi-wireable speaker outputs and the option to add a stereo Aktiv card for improved audio performance.

Switch mode power supply

The power supply in most amplifiers contains a large and heavy transformer, a rectifier and reservoir capacitors. These components convert the voltage of the mains supply to the low voltage required by electronic circuits, and supply this lower voltage to the amplifier circuitry at a constant level – regardless of the demands of the amplifier. Such power supplies use electricity inefficiently and cause mains power distortion which can lead to electrical and acoustic noise.

In a switch mode power supply, the incoming mains voltage is chopped up by very fast semiconductor switches and is then passed through a small transformer and other components, which convert the voltage to the value needed by the amplifier circuitry. By controlling the timing of the semiconductor switches, the voltage supplied to the amplifier circuitry can be instantly altered to suit demand. Linn’s switch mode power supply is not only efficient, it also eliminates mains power distortion resulting in superior performance and sound quality.

Aktiv cards

The Linn 2250 power amplifier has been engineered to support both passive and active loudspeaker crossovers. In a passive crossover the audio signal from a system’s amplifier is split by circuitry inside the loudspeaker into bass and treble, or bass, mid and treble (depending on the type and size of loudspeaker). With a passive system a portion of the energy in the audio signal is required to power the crossover, which naturally has an affect on the overall quality of sound reproduction. The benefit of an active system is that the audio signal is split within the amplifier and each split ‘segment’ is further amplified before being fed to the speakers. Active crossover systems sound more dynamic than passive systems as the speakers are provided with more energy to drive them.

Linn have developed active crossovers, called Aktiv cards, which have been optimised for our range of loudspeakers. Once fitted, Aktiv cards can be fine-tuned to suit the requirements of your room and enhance your listening experience. Aktiv cards can be fitted into your Linn 2250 power amplifier by your local Linn specialist retailer.
