Atohm S250-X Ice Power

Amplifier Module Class D Subwoofer 220W 4Ω

Atohm S250-X Ice Power Module Amplificateur Class D Subwoofer 220W 4Ω

Specialized in the design and manufacture of high-end loudspeakers and loudspeaker cabinets, Atohm also designs and offers amplification modules with a very high level of performance. Thanks to their sophisticated signal processing, Atohm's modules offer a wide range of settings and connections to meet the most demanding applications, such as active subwoofers in closed load or Bass-Reflex, active loudspeakers or monophonic power blocks. All of this with excellent technical performance and musicality in a small footprint.

Important studies have been conducted by the brand on components, schematics, layout topology, power supply as well as general construction to develop the best products.

The S250-X Atohm Amplifier Module includes many features and specifications:

  • Ice output stage Power™ with 220W RMS under 4Ω. Class D technology, ensuring an excellent efficiency of 80% and a high damping factor, making the module compatible with any load impedance greater than or equal to 3Ω. Great musicality and generous power in a very small footprint.
  • Peak limiter section with two levels: 0dB and -1dB with "Soft Clipping". When clipped (excess input level), a sinusoidal signal is transformed into a square signal containing an infinite number of perfectly audible odd harmonics (distortion). In a subwoofer application, this distortion distorts the sound and makes it possible to perfectly locate the subwoofer because it contains high frequencies. The clipping limiter associated with the low-pass filter stages (variable or LFE) reduces or eliminates clipping distortion.
  • X-GUARD technology overcomes the drawbacks of a conventional subsonic filter by ensuring that the speaker excursion never exceeds an absolute limit (risk of breakage, very high distortion) regardless of the amplitude of the input signal. This technology preserves the signal and its phase (unlike a subsonic filter). The extreme bass is more faithful, the connection with the main speakers more homogeneous and the speaker protected. The S250-X offers two internal settings (X30 or X35) via jumpers, in addition to the two settings available on the front panel: X-GUARD1 and X-GUARD2 (refer to the S250-X manual).

It is possible to connect the module via the pre-out/subwoofer outputs of a preamplifier/processor or directly to the speaker outputs (in parallel) of a conventional stereo amplifier. The S250-X module can also be by-passed to high-performance HiFi broadband use (mono block) via a simple internal switch. In this case, only the gain control remains active. This can be used for the realization of monitor loudspeakers for example.

bon achat
Je possède un caisson de la marque final. Le module de 300 w ayant décidé d'arrêter de fonctionner au bout de 15 ans, j'ai longtemps hésité à acheter un nouveau caisson. Finalement j'ai opté pour celui-ci et je suis vraiment satisfait. Par contre j'ai règlé le curseur sur "closed" et ça change vraiment tout côté dynamisme. ( hp de 26 cm de diamètre.)
