All components have been optimized for long durability and ease of servicing.\u003c\/p\u003e\n\u003cp\u003eThe design is modern and timeless: aesthetically pleasing on the eye, with all controls placed on the back of the amplifier.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eStereo is mono plus mono\u003c\/u\u003e\u003c\/p\u003e\n\u003cp\u003eTwo is always one plus one. This truism has a deeper meaning in amplifier technology: By separating the amplification power into two housings, one achieves several decisive advantages over integrated power amplifiers or integrated integrated amplifiers:\u003c\/p\u003e\n\u003cp\u003eMono power amplifiers can be installed directly at the loudspeaker. The supply cables to the speakers can be extremely short. Electrical and acoustic losses are reduced to a minimum, which is particularly important with low-impedance loudspeakers.\u003c\/p\u003e\n\u003cp\u003eCrosstalk between the two stereo channels is excluded when using mono power amplifiers. The spatial impression of the music is therefore fundamentally more perfect than when using integrated two-channel amplifiers.\u003c\/p\u003e\n\u003cp\u003eThe circuitry within the power stage is divided into four areas:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe amplifier stages, i.e. voltage amplifiers (driver stage) and current amplifiers (output stage)\u003c\/li\u003e\n\u003cli\u003eOperating and protection electronics to control and manage all functions.\u003c\/li\u003e\n\u003cli\u003eInstrument and status displays to inform the user.\u003c\/li\u003e\n\u003cli\u003ePower supply unit to power the entire device.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe result is a musical masterpiece of organic fluidity, huge soundstage, multi-faceted layering and separation, precise and holographic positioning, and a tonal balance that creates a truly live event for the listener.\u003c\/p\u003e\n\u003cp\u003eThe RESTEK power amplifier EXTENT is designed for a minimum load impedance of 1 ohm. An output power of more than 1,000 watts can be called up at this impedance.\u003c\/p\u003e\n\u003cp\u003eThis means that the RESTEK EXTENT can also drive loudspeakers that are considered to be critical in excellent quality.\u003c\/p\u003e\n\u003cp\u003eA successful design is characterised by timeless modernity\u003c\/p\u003e\n\u003cp\u003eAll controls were relegated to the back of the device except for the on \/ off switch. This not only contributes to the timelessly elegant design, but also makes the signal paths in the device short.\u003c\/p\u003e\n\u003cp\u003eClear displays give the user information about the status of the mono power amplifiers at all times. The large VU meter shows the applied output voltage and thus the power output. The backlight can be switched off at any time on request.\u003c\/p\u003e\n\u003cp\u003eEight LED displays on the front show the operating or operating status and provide information about the status of the protective circuits.\u003c\/p\u003e\n\u003cp\u003e\u003cu\u003eFeatures of the EXTENT power amplifier from the E series\u003c\/u\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMirror-symmetrical circuit construction\u003c\/li\u003e\n\u003cli\u003eCentral performance indicator\u003c\/li\u003e\n\u003cli\u003eSymmetrical and asymmetrical inputs\u003c\/li\u003e\n\u003cli\u003eOvertemperature and offset monitoring\u003c\/li\u003e\n\u003cli\u003eCan be switched on remotely via the preamplifier\u003c\/li\u003e\n\u003cli\u003eCold lighting\u003c\/li\u003e\n\u003cli\u003eGerman manufacturing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cu\u003eSpecifications :\u003c\/u\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePower Output: 260 watts into 8 ohms, 500 watts at 4 ohms, 840 watts into 2 ohms\u003c\/li\u003e\n\u003cli\u003eMusic Power: 350 watts into 8 ohms, 680 watts at 4 ohms, 1100 watts into 2 ohms\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 5 Hz ...... 150 kHz at-3dB\u003c\/li\u003e\n\u003cli\u003eTHD: \u0026lt;0.02%\u003c\/li\u003e\n\u003cli\u003eSignal to noise ratio:\u0026gt; 118 dBA\u003c\/li\u003e\n\u003cli\u003eRise time: \u0026lt;1.5 usec\u003c\/li\u003e\n\u003cli\u003eSlew Rate:\u0026gt; 40 V \/ usec\u003c\/li\u003e\n\u003cli\u003eDamping factor:\u0026gt; 320 (8 ohms, 1kHz)\u003c\/li\u003e\n\u003cli\u003eInput Sensitivity: 2 V rms\u003c\/li\u003e\n\u003cli\u003eInput Impedance: 47 ohms unbalanced, 10 ohms balanced\u003c\/li\u003e\n\u003cli\u003eDimensions (WxHxD): 340 x 210 x 506 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 35 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Restek","offers":[{"title":"Acrylic","offer_id":52740000416010,"sku":null,"price":6500.0,"currency_code":"GBP","in_stock":true},{"title":"Aluminium","offer_id":52740000448778,"sku":null,"price":6100.0,"currency_code":"GBP","in_stock":true},{"title":"Black","offer_id":52740000481546,"sku":null,"price":6100.0,"currency_code":"GBP","in_stock":true},{"title":"Chrome","offer_id":52740000514314,"sku":null,"price":6500.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0917\/3283\/6618\/files\/restek-extent-mono-power-amplifier-each--785-1-p.jpg?v=1773933955","url":"https:\/\/audioemotion.co.uk\/products\/restek-extent-mono-power-amplifier-each","provider":"Audio Emotion Limited","version":"1.0","type":"link"}
