With an amplifier output of 2 x 370 W (4 Ω) [2 x 420 W (2 Ω); 2 x 200 W (8 Ω)], it really does have enough power reserves to power any speaker.\u003c\/p\u003e\n\n \u003cp\u003eDespite its compact height, the Performer s900 stereo power amplifier has some thanks\u003cbr\u003e SPL VOLTAiR technology delivers headroom that is second to none, pampering you with detailed, lively, honest and musically exceptional sound.\u003c\/p\u003e\n\n\u003cp\u003e Design – a matter of good taste\u003cbr\u003e Visually, the SPL Performer s900 stereo power amplifier fits perfectly into the SPL HiFi \"Professional Fidelity\" line and is of course available in the three basic colours black, red or silver.\u003c\/p\u003e\n\n\u003cp\u003e Conventional solid-state power amplifiers quickly work at the limits of the components used: unsightly distortions occur. Tube power amplifiers also distort in this limit range, but this manifests itself in a rather softer sound.\u003c\/p\u003e\n\n \u003cp\u003eThanks to VOLTAiR technology, the Performer s900 can process significantly higher levels without distortion. All components work continuously in the optimal working range. The result is a very pleasant, natural and relaxed sound experience. Enjoy your music in every detail and without listening fatigue.\u003c\/p\u003e\n\n\u003cp\u003e Full speed ahead\u003cbr\u003e In the Performer s900, separate voltage and power amplifier stages ensure a stable operating point of the amplifier circuit, which uses Class AB technology. Thanks to their negative feedback path, feedback from the loudspeaker to the input stage is also eliminated. This allows the SPL VOLTAiR technology to demonstrate its full performance.\u003c\/p\u003e\n\n\u003cp\u003e Free choice\u003cbr\u003e The Performer s900 has a stereo pair of XLR and RCA inputs.\u003cbr\u003e This means that it is compatible with all commercially available preamplifiers without the use of adapters. \u003cbr\u003eThe corresponding stereo input can be selected using the Input Select switch on the rear.\u003c\/p\u003e\n\n\u003cp\u003e Get in shape\u003cbr\u003e In relation to the Performer s900, “fit” – as in English – means adapted. And you can adjust the input sensitivity in 0.5 dB increments. From 0 dB to -5.5 dB. Unlike a panorama potentiometer in a preamplifier, this is the audiophile solution for acoustically problematic rooms or speaker configurations. The optimum working range of the speakers and the preamplifier can also be ideally adjusted.\u003c\/p\u003e\n\n\u003cp\u003e Strong connection\u003cbr\u003e The speaker terminals can accommodate both banana plugs and stranded wire with a diameter of up to 4 mm. It is not permitted to connect any speaker with an impedance lower than 2 ohms.\u003c\/p\u003e\n\n\u003cp\u003e AMP CTL \u003cbr\u003eThe standby mode of the power amplifier can be activated and deactivated using the AMP CTL connection between a preamplifier, such as the Director Mk2, Elector, Phonitor x or the crossover. To do this, connect the 3.5 mm jack sockets with a cable with 3.5 mm mono or stereo jack plugs. Preamplifiers from other manufacturers can also activate and deactivate the standby mode of the Performer s900 using the 12 V trigger input.\u003c\/p\u003e\n\n\u003cp\u003e Better safe than sorry\u003cbr\u003e The Performer s900 has a protection circuit against direct voltage and one against overheating. \u003cbr\u003eIf DC voltage is detected, the Performer s900 output stage automatically switches off and the Protect LED on the front lights up red. To protect the Performer s900 from the unlikely event of overheating, a temperature sensor on the heat sinks continuously monitors the temperature of the device. The TEMP LED lights up yellow when the Performer s900 gets too hot and switches it off until the power amplifier has cooled down again.\u003c\/p\u003e\n\n\u003cp\u003e It sounds good\u003cbr\u003e For all Professional Fidelity Series devices, we develop not only according to plan, but also by ear from the very beginning. Many of the basic components are installed on the circuit boards using through-hole mounting (THT). This way, we can ensure that we can install the components that sound best.\u003c\/p\u003e\n\n\u003cp\u003e VOLTAiR Technology \u003cbr\u003e120V Technology is our benchmark technology. It is unique in the audio industry worldwide because it operates with a DC voltage of 120 volts. This corresponds to four times the operating voltage of IC-based semiconductor op-amps. In our Professional Fidelity Series we refer to this unrivaled technology as VOLTAiR Technology.\u003c\/p\u003e\n\n\u003cp\u003e The highest possible audio quality requires the highest possible audio operating voltage.\u003cbr\u003e 120V technology operates at +\/- 60V. To handle such a high voltage, we have developed special proprietary op-amps that can operate at a DC voltage of +\/- 60V: the SPL 120V SUPRA op-amps. This high voltage would destroy conventional components and op-amps.\u003c\/p\u003e\n\n \u003cp\u003e120V technology achieves exceptional technical specifications and sonic advantages. Technically, in terms of dynamic range, signal-to-noise ratio and overload resistance. Sonically, in terms of richness of detail and an absolutely relaxed listening experience.\u003c\/p\u003e\n\n\u003cp\u003e By the way, the “120V” in the name of the technology has nothing to do with the local mains voltage of the socket. It is the operating voltage in the device with which the audio signals are processed.\u003c\/p\u003e\n\n\u003cp\u003e The mains voltage of the socket is transformed into the required secondary voltage in the internal linear power supply of the device with a toroidal transformer. Rectifiers convert this AC voltage into the required DC voltages in the audio device.\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003c!----\u003e","brand":"SPL","offers":[{"title":"Default Title","offer_id":55866991477060,"sku":"SPL S900 NERO USATO","price":2990.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0508\/6527\/5040\/files\/IMG_4792-dimensionigrandi.jpg?v=1778243240","url":"https:\/\/stereo-box.it\/en\/products\/spl-performer-s900-finale-di-potenza-usato","provider":"STEREO BOX","version":"1.0","type":"link"}
