Beautifully designed inside and outside.\u003c\/p\u003e\n\u003cp\u003eSoundastic Reference is a dual mono audio amplifier, manufactured in line with cutting edge technologies and worldwide standards of quality and reliability. \u003c\/p\u003e\n\u003cp\u003eAn anti-magnetic alloy casing ensures significant resistance to external interference and the power supply consists of two Thyssen 500 VA toroidal transformers.\u003c\/p\u003e\n\u003cp\u003eThe transformers are characterised by low level loss and well as high levels of inductance, small in size they have a very low magnetic dispersion field. They have been installed on anti-vibration bases and secured by means of a special epoxy mixture, while the fixing to the amplifier chassis has been carried out using a copper sheet with thickness of 3 mm. \u003c\/p\u003e\n\u003cp\u003eOutput transistors have been installed on a 15 mm thick aluminium plate in order to eliminate the residual vibrations caused by the transformers. \u003c\/p\u003e\n\u003cp\u003eThe front plate is made of  aviation-grade aluminium alloys. The precisely optimised convection cooling system allowed to reduce the size of the amplifier.\u003c\/p\u003e\n\u003cp\u003eA new delayed transformer activation system (soft start) was designed, including an anti-interference filter. Such a solution eliminates overvoltage when turning the amplifier on, as well as the adverse impact of the above on the lifetime of electrolytic capacitors. \u003c\/p\u003e\n\u003cp\u003eThe rear plate of the amplifier has been fitted with speaker terminals, separate RCA sockets, and XLR inputs (professional Amphenol sockets). The other RCA sockets are gilded Japanese Jalco sockets. \u003c\/p\u003e\n\u003cp\u003eAmplifier front: mains switch and input selector are manufactured by C\u0026amp;K, and the motor-controlled volume potentiometer is the Blue Velvet Alps model, enjoying a great deal of respect in the world of audiophiles which also performs the role of a passive preamplifier. \u003c\/p\u003e\n\u003cp\u003eSoundastic Reference features record player inputs for MC and MM inserts, in which THT (discreet) elements have been applied. The RIAA curves have been modified by adding an additional 3.2 s (Neumann) time constant, which led to achieving greater spatiality of the musical image. In each situation, both when using a record player and at each of the in line input type.\u003c\/p\u003e\n\u003cp\u003eThe amplifier is characterised by its approximation of the appreciated vacuum tube sound, while at the same time retaining all the best features of a transistor-based amplifier, such as speed and control over low frequencies. The final path of the signal is the two power amplifiers in a balanced system, powered by electrolytic capacitors of the Nippon Chemi-Con company, having a total capacity of 48 000 F. The design of the power amplifiers is based on the original patent of the Soundastic company, RP No. 176514.\u003c\/p\u003e\n\u003cp\u003eWithin the signal channel, the amplifiers do not feature any capacity element (capacitors). It has been designed with the use of only the JFET transistors and a symmetrical input. This ensures sound neutrality that is sought-after among the highest class audio devices. The end transistors are two pairs per each channel (8 pcs in total) of American MOSFET transistors from the International Rectifier Company. \u003c\/p\u003e\n\u003cp\u003eThe remote control weighing 0.370 kg is made of solid aluminium.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eSpecifications\u003c\/u\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePower: 2 x 140 W\/8  (CLASS AB)2 x 260 W\/4  (CLASS AB)\u003c\/li\u003e\n\u003cli\u003eMinimum impedance load: 1  (instantaneous)\u003c\/li\u003e\n\u003cli\u003ePower consumption: STATIC 40 VAPEAK 1200 VA\u003c\/li\u003e\n\u003cli\u003eDistortion  THD: 0.05% at 1 W \/ 8 0.02% at 120 W \/ 8 \u003c\/li\u003e\n\u003cli\u003eFrequency response: 5 Hz  100 kHz  3 dB \/ 1 W \/ 8\u003c\/li\u003e\n\u003cli\u003eNon-linearities in the frequency band: 10  30,000 Hz: ± 0.01 dB\u003c\/li\u003e\n\u003cli\u003eSlew rate: 150 V\/s\u003c\/li\u003e\n\u003cli\u003eSignal  noise ratio: 130 dB (IHF  A)\u003c\/li\u003e\n\u003cli\u003eInputs: 4 x universal  RCA, XLR Amphenol, Separated CD \/ DAC  RCA, Phono MM  RCA\u003c\/li\u003e\n\u003cli\u003eSensitivity of inputs: 500 mV  universal inputs and dedicated CD \/ DAC, 500 mV  XLR input, 3 mV  MM input, 0,2 mV  MC input\u003c\/li\u003e\n\u003cli\u003eImpedance inputs: 100 k; universal inputs and CD \/ DAC, 22 k XLR, 47 k MM, 100  MC\u003c\/li\u003e\n\u003cli\u003ePotentiometer (volume): the highest precision model the Alps  Blue Velvet\u003c\/li\u003e\n\u003cli\u003eTransformers: 2 x toroidal, 500 VA each\u003c\/li\u003e\n\u003cli\u003eCapacitors filtering the supply voltage: 4 x 12 000 uF  Nippon Chemi-Con\u003c\/li\u003e\n\u003cli\u003eAdvanced protection system: against short-circuiting of the loudspeakers and a stream of DC voltage output\u003c\/li\u003e\n\u003cli\u003eRemote control: RC5 code (volume)\u003c\/li\u003e\n\u003cli\u003eThe DM 250 amplifier fulfills all requirements and standards valid in the EU\u003c\/li\u003e\n\u003cli\u003eNet weight: 16 kg\u003c\/li\u003e\n\u003cli\u003eDimensions: 430 x 95 x 358 mm\u003c\/li\u003e\n\u003cli\u003eManufacturers warranty: 24 months\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Soundastic","offers":[{"title":"Default Title","offer_id":51938608709898,"sku":"SOUNDASTIC-8553","price":5495.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0917\/3283\/6618\/files\/soundastic-reference-stereo-integrated-amplifier-41309-p.jpg?v=1760363675","url":"https:\/\/audioemotion.co.uk\/products\/snd-ast-ref-int","provider":"Audio Emotion Limited","version":"1.0","type":"link"}
