{"product_id":"clearaudiosmartpower12vbl","title":"Clearaudio Smart Power 12V Battery Power Supply, Black","description":"\u003cp\u003eThe Clearaudio Smart Power 12V is a battery power supply that fully disconnects a 12-volt turntable from the mains during operation and feeds the drive motor from a NiMH battery with pure DC current.\u003c\/p\u003e\u003cp\u003eAs long as you're listening, the power comes from the battery – no mains hum, no voltage spikes, none of what the fridge and LED dimmers send back into the line all day long. When the charge runs low, the unit recharges itself automatically and keeps feeding your turntable in the meantime. The stylus notices nothing.\u003c\/p\u003e\u003ch2\u003eWhy the Smart Power 12V?\u003c\/h2\u003e\u003cp\u003eA belt-drive turntable lives on a steady speed, and that depends directly on how cleanly the motor is fed. The mains is a poor supplier for that: switching power supplies, dimmers and chargers all leave traces. In battery mode there's simply no connection left for any of that to travel over. Add to that the battery's very low internal resistance – it delivers current faster and with a flatter discharge curve than any plug-in power supply ever could.\u003c\/p\u003e\u003ch2\u003eWhat you hear\u003c\/h2\u003e\u003cp\u003eThe so-called \"night effect\", just around the clock: a quieter background, instruments that keep their place, and bass that grips dry rather than spreading out. It's most obvious in quiet passages – where there seemed to be nothing before, you suddenly hear space.\u003c\/p\u003e\u003ch3\u003eWho is the Smart Power 12V for?\u003c\/h3\u003e\u003cp\u003eFor you, if you own a Clearaudio Concept or a Performance DC and want to squeeze out the last bit of speed stability without swapping the whole turntable. Plain talk: the voltage has to match – turntables in the Ovation, Innovation and Statement series run on 24 volts and need the larger model. And batteries are wear parts; after a few years capacity drops. That's not a drama, just a service appointment.\u003c\/p\u003e\u003ch2\u003eOur verdict\u003c\/h2\u003e\u003cp\u003eOne of the few accessories where the effect isn't a matter of imagination. The Smart Power 12V brings a Concept or Performance DC sonically closer to the next league up, without you having to change anything about placement, alignment or cartridge. If you want to keep your turntable anyway, this is the least spectacular sensible step forward.\u003c\/p\u003e\u003ch2\u003eTechnical data\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e battery power supply with complete mains isolation during operation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery:\u003c\/strong\u003e nickel-metal hydride (NiMH), 5000 mAh\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e 12 V DC, max. 1.6 A, electronically fused (slow-blow)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharging:\u003c\/strong\u003e 19 V plug-in power supply, 100–240 V AC, 50–60 Hz, max. 1.6 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower consumption:\u003c\/strong\u003e 6.5–33 W in operation, 0 W when switched off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e clearaudio Concept, Concept Active and Performance DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing:\u003c\/strong\u003e aluminium, black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W × H × D):\u003c\/strong\u003e 110 × 46 × 350 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e approx. 2.2 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 2 years (battery excluded)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e Smart Power 12V with 160 cm power cable, 19 V plug-in power supply, instruction manual, warranty card\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eWhich turntables suit the Smart Power 12V?\u003c\/h3\u003e\u003cp\u003eThe Smart Power 12V is built for clearaudio turntables with a 12-volt input, specifically Concept, Concept Active and Performance DC. Turntables in the Ovation, Innovation and Statement series run on 24 volts and need the larger Smart Power 24V. If in doubt, check the label on your original power supply or just ask us.\u003c\/p\u003e\u003ch3\u003eWhat happens if the battery runs flat while listening?\u003c\/h3\u003e\u003cp\u003eNothing you'll notice. The unit automatically switches to charging or buffer mode and keeps feeding your turntable in the meantime – the record keeps spinning without interruption. You get the last bit of quiet by unplugging the charger while listening and running purely on battery.\u003c\/p\u003e\u003ch3\u003eHow is it different from the Professional Power 12V?\u003c\/h3\u003e\u003cp\u003eThe Professional Power 12V is a linear power supply: it cleans and stabilises the power but stays connected to the mains. The Smart Power goes one step further and cuts that connection completely during operation. Both improve speed stability; the battery solution is the more consistent – and more elaborate – one.\u003c\/p\u003e\u003ch3\u003eWhy buy the Clearaudio Smart Power 12V from HD Zürisee?\u003c\/h3\u003e\u003cp\u003eBecause we've been setting up, aligning and servicing Clearaudio turntables for many years – and we handle the battery service in-house later on, instead of sending you off to a service centre.
