{"product_id":"avm-ovation-sa-6-3-stereo-endstufe-silber","title":"AVM Ovation SA 6.3 Stereo Power Amplifier, Silver","description":"\u003cp\u003eThe AVM Ovation SA 6.3 is a MOS-FET stereo power amplifier in Class-A\/AB high-current design, delivering 2 × 200 watts at 8 ohms and 2 × 350 watts at 4 ohms.\u003c\/p\u003e\n\u003cp\u003eIt's the transistor power amplifier of the Ovation range: no tube glow, no off-the-shelf tonal colour, but a power supplier that passes the preamplifier's signal on to the speakers as unchanged as possible. Built in the classic 19-inch format, here with a silver anodised aluminium front.\u003c\/p\u003e\n\u003ch2\u003eWhy the Ovation SA 6.3?\u003c\/h2\u003e\n\u003cp\u003eBecause it stays calm where others start to struggle. 20 high-current MOS-FETs per channel deliver up to 180 amps of peak current – the reserve that impedance-critical speakers actually draw on. Supply comes from a 1000 VA toroidal transformer and three separate power supplies, so the output stages, processor and input circuitry don't get in each other's way. The input stages are fully balanced and fully DC-coupled. In numbers: damping factor above 500, signal-to-noise ratio of 101 dB(A), distortion below 0.01 percent, frequency response from under 5 hertz to over 100 kilohertz.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cp\u003eOne RCA and one XLR high-level input each, used alternatively but not simultaneously, two bi-wire-capable speaker terminal pairs and a large, blue-lit graphic display. In the menu you set brightness, display mode, operating mode and speaker impedance, and can display the power being drawn if needed. The AIR trigger switches the power amplifier on and off together with the preamplifier. A remote control isn't included – without volume control, there'd be nothing for it to do anyway. This version comes with a silver anodised aluminium front.\u003c\/p\u003e\n\u003ch3\u003eWho is the Ovation SA 6.3 right for?\u003c\/h3\u003e\n\u003cp\u003ePlain talk: without a preamplifier, nothing happens here at all. The SA 6.3 has no volume control, no source inputs and no streaming on board. Anyone wanting everything in one chassis should go for an integrated amplifier. But anyone who deliberately separates things – preamplifier here, power amplifier there – and owns speakers that want more than good intentions gets a power amplifier that stays in control when things get demanding. And at 21 kilograms, you can still carry it alone.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe SA 6.3 doesn't make a fuss about itself. It delivers power, keeps the bass firm, stays neutral and disappears sonically behind the music – exactly what a good power amplifier should do. Anyone looking for warmth and bloom will find that one model up, with the tube. Anyone wanting precision and control has already found it here.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e MOS-FET stereo power amplifier, Class-A\/AB high-current design, pure transistor circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 2 × 200 W at 8 Ω, 2 × 350 W at 4 Ω (AVM states no 2 Ω value)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput stage:\u003c\/strong\u003e 20 high-current MOS-FETs per channel, up to 180 A peak current\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower supply:\u003c\/strong\u003e 1 × 1000 VA toroidal transformer, 3 separate power supplies\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput stages:\u003c\/strong\u003e fully balanced, fully DC-coupled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 1 × RCA (stereo pair), 1 × XLR (stereo pair), high level – usable alternatively only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput impedance:\u003c\/strong\u003e 6.8 kΩ (RCA) \/ 14 kΩ (XLR)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker connection:\u003c\/strong\u003e 2 pairs of screw terminals, internally paralleled, bi-wire capable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamping factor:\u003c\/strong\u003e \u0026gt; 500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e \u0026lt; 5 Hz – \u0026gt; 100 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistortion:\u003c\/strong\u003e \u0026lt; 0.01 % (25 W \/ 4 Ω)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal-to-noise ratio:\u003c\/strong\u003e 101 dB(A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection circuits:\u003c\/strong\u003e over-temperature and short-circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation:\u003c\/strong\u003e blue-lit graphic display with power and peak display, menu for brightness, display mode, operating mode and speaker impedance, AIR trigger (AVM Intelligent Remote)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrigger:\u003c\/strong\u003e 3.5 mm switching input for the preamplifier's switching voltage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemote control:\u003c\/strong\u003e none – not included, no volume control on the unit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridge mode:\u003c\/strong\u003e not provided by AVM (for mono operation: Ovation MA 6.3)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower supply (mains):\u003c\/strong\u003e 120\/230 V, 50\/60 Hz, max. power consumption 1000 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandby:\u003c\/strong\u003e \u0026lt; 0.5 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W × H × D):\u003c\/strong\u003e 430 × 130 × 390 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 21 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 4 years with registration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Aluminium Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScope of delivery:\u003c\/strong\u003e power amplifier, mains cable, trigger plug\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eDo I need a preamplifier for the AVM Ovation SA 6.3?\u003c\/h3\u003e\n\u003cp\u003eYes. Without a preamplifier, the SA 6.3 stays silent, as it has neither volume control nor inputs for sources. It works with a preamplifier such as the AVM Ovation PA 8.3 or the SD 8.3, connected via RCA or XLR. Both inputs are available, but only one can ever be used at a time.\u003c\/p\u003e\n\u003ch3\u003eWhat's the difference between the SA 6.3 and the SA 8.3?\u003c\/h3\u003e\n\u003cp\u003eThe 8.3 plays in a bigger league: AVM states over 2 × 230 watts at 8 ohms, over 2 × 420 watts at 4 ohms and over 2 × 700 watts at 2 ohms for it, plus a tube input stage, dual-mono power supply and 24 instead of 20 MOS-FETs per channel. At 21 instead of 42 kilograms, the SA 6.3 is half the weight and measures as the tighter variant.\u003c\/p\u003e\n\u003ch3\u003eCan the AVM Ovation SA 6.3 be bridged to mono?\u003c\/h3\u003e\n\u003cp\u003eNo. The manual describes no bridge or mono operation; AVM does not provide for this operating mode on the SA 6.3. For mono operation, there's the Ovation MA 6.3 instead. So anyone needing more power per channel switches to mono power amplifiers rather than bridging.\u003c\/p\u003e\n\u003ch3\u003eCan I switch the SA 6.3's two speaker outputs separately?\u003c\/h3\u003e\n\u003cp\u003eNo. According to the manual, the two terminal pairs are internally paralleled and primarily intended for bi-wiring. There's no A\/B switching between two pairs of speakers; both always run together. We're happy to check beforehand whether your speakers go along with that.\u003c\/p\u003e\n\u003ch3\u003eWhich speakers suit the AVM Ovation SA 6.3?\u003c\/h3\u003e\n\u003cp\u003eWith 2 × 200 watts at 8 ohms, 2 × 350 watts at 4 ohms, up to 180 amps of peak current and a damping factor above 500, the SA 6.3 confidently drives even large floorstanding speakers with an unruly impedance curve. Which ones specifically suit your room is something we're happy to work out together.\u003c\/p\u003e\n\u003ch3\u003eWhy buy the AVM Ovation SA 6.3 at HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause we'll tell you if a smaller power amplifier is enough for your room.
