If direct current (DC) is detected, the output stage switches off automatically and the Protect LED lights up red.\n\u003c\/p\u003e\n\u003cp\u003e\nTo protect the s800 against the unlikely event of overheating, a temperature sensor at the heatsinks continuously monitors the temperature of the device. The TEMP LED lights up yellow when the Performer s800 is getting too hot.\n\u003c\/p\u003e\n\u003cp\u003e\nAs a result of this the output stage is switched off and the fans run on high-speed until the device has cooled down.\n\u003c\/p\u003e\n\n\u003ch4\u003eAs one calls into the forest, so it echoes out.\u003c\/h4\u003e\n\u003cp\u003e\nThis saying inspired SPL to send the input signal out again in order to drive another power amplifier in bi-amping mode.\n\u003c\/p\u003e\n\n\u003ch4\u003eTrim to fit\u003c\/h4\u003e\n\u003cp\u003e\nWith reference to the Performer s800, “fit” means adapted.\n\u003c\/p\u003e\n\u003cp\u003e\nYou can adapt the input sensitivity in 0.5 dB steps from 0 dB to -5.5 dB. In contrast to a panorama potentiometer in a preamplifier, this trim switch is the more audiophile solution.\n\u003c\/p\u003e\n\u003cp\u003e\nIn addition, the difference in loudness of loudspeakers can be elegantly compensated in bi-amping mode.\n\u003c\/p\u003e\n\n\u003ch4\u003ePower to the speakers\u003c\/h4\u003e\n\u003cp\u003e\nThe loudspeaker binding posts can accommodate banana plugs as well as a stranded wire with a diameter of up to 4 mm.\n\u003c\/p\u003e\n\u003cp\u003e\nThus, any common type of speaker cable and in bi-wiring mode even both connection types can be used together.\n\u003c\/p\u003e\n\u003cp\u003e\nHowever, we do not recommend connecting a speaker with less than 4 ohms impedance.\n\u003c\/p\u003e\n\n\u003ch4\u003eBridge\u003c\/h4\u003e\n\u003cp\u003e\nYou can turn the two power amplifier channels into one power amplifier by connecting only the two plus pole terminals to the loudspeaker. This allows 450 W into 8 Ohm in mono operation mode.\n\u003c\/p\u003e\n\n\u003ch4\u003eTrigger me\u003c\/h4\u003e\n\u003cp\u003e\nThe standby mode of the power amplifier can be switched on and off using the AMP CTL connection between an SPL Professional Fidelity preamplifier, such as the Director Mk2.\n\u003c\/p\u003e\n\u003cp\u003e\nTo do this, connect the 3.5 mm phone jacks to a cable with 3.5 mm mono or stereo phone plugs. It is not recommended to connect devices from third parties to the AMP CTL jack of the Performer s800.\n\u003c\/p\u003e\n\u003cp\u003e\nUse only SPL Professional Fidelity series preamplifier for amplifier control. Never connect other devices to the AMP CTL jack.\n\u003c\/p\u003e\n\n\u003ch4\u003eFull power\u003c\/h4\u003e\n\u003cp\u003e\nThe Performer s800 features individual amplification stages for voltage and power amplification, which ensures a perfect operating of the class-AB amplifier circuit.\n\u003c\/p\u003e\n\u003cp\u003e\nThanks to each stage’s own negative feedback path, it is ruled out that feedbacks from the loudspeaker are interacting with the input stage – this way the SPL VOLTAiR Technology can play out its full performance.\n\u003c\/p\u003e\n\n\u003ch4\u003eSounds good\u003c\/h4\u003e\n\u003cp\u003e\nWith all devices of the Professional Fidelity series we develop not only according to plan, but also by ear. Many important components are installed on the circuit boards using Through-hole technology. This way it is ensured that the best sounding components are used.\n\u003c\/p\u003e\n\n\u003ch4\u003eThe VOLTAiR Technology\u003c\/h4\u003e\n\u003cp\u003e\nThe 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps. In our Professional Fidelity series, we refer to this unsurpassed technology as VOLTAiR technology.\n\u003c\/p\u003e\n\u003cp\u003e\nThe highest possible audio quality requires the highest possible audio operating voltage.\n\u003c\/p\u003e\n\u003cp\u003e\nThe 120V technology works with +\/-60 V. To be able to handle such a high voltage, we have developed special proprietary operational amplifiers that can operate with a DC voltage of +\/-60 V: the SPL 120V SUPRA operational amplifiers. This high voltage would destroy conventional components and operational amplifiers.\n\u003c\/p\u003e\n\u003cp\u003e\nThe 120V technology achieves exceptional technical specifications and sonic benefits. Technically, in terms of dynamic range, signal-to-noise ratio and headroom. Sonically, in terms of richness of detail and an absolutely relaxed listening experience.\n\u003c\/p\u003e\n\u003cp\u003e\nBy the way, the “120V” in the name of the technology has nothing to do with the local mains voltage from the mains power socket. This is about the operating voltage inside the device with which the audio signals are processed.\n\u003c\/p\u003e\n\u003cp\u003e\nThe mains voltage from the mains power socket is transformed to the required secondary voltage in the device’s internal linear power supply with toroidal transformer. Rectifiers convert this AC voltage into DC voltage required in the audio device.\n\u003c\/p\u003e\n\n\u003ch4\u003eComparison\u003c\/h4\u003e\n\u003cp\u003e\nMost audio devices work with an internal operating voltage of +\/-15 volts and can thus process a maximum input level of +21.5 dBu. If a DAC, for example, has an output level of +22 dBu at 0 dBFS, level peaks of the music material would already cause overloads in the input stage of the device. All components in the audio device often operate at their limits. The result is an unsteady sound that causes stress and faster ear fatigue.\n\u003c\/p\u003e\n\u003cp\u003e\nSPL devices with VOLTAiR technology can handle input levels of +32.5 dBu thanks to the higher internal operating voltage of +\/- 60 volts – thus offering 12 dB more headroom. All components consequently operate continuously in the optimum operating range. The result is a very pleasant, natural and relaxed sound experience. So you can enjoy your music in every detail.\n\u003c\/p\u003e","brand":"Audio Art Cable USA","offers":[{"title":"Black","offer_id":42561210941486,"sku":"SPL-PERFORMER-s800","price":3500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0035\/4058\/2446\/files\/spl-1600-performer-s800-black-front.jpg?v=1773093252","url":"https:\/\/audioartcable.com\/products\/spl-performer-s800-power-amplifier-demo","provider":"Audio Art Cable","version":"1.0","type":"link"}
