{"product_id":"powerblok-pure-balanced-mains-units","title":"Powerblok Pure Balanced Mains Units","description":"The Powerblok series of AC Balanced Mains Transformers have been designed specifically for use in conjunction with high quality domestic audio systems for the specific purpose of improving sound quality.\u003cbr\u003e\u003cbr\u003e\n\nSeveral types of noise and distortion are reduced with the use of these conditioners. The key parameter is the reduction of 'common mode' noise, that is noise and distortion that is equal to both the live and neutral wires on the incoming mains.\u003cbr\u003e\u003cbr\u003e\n\nBalanced Power 250va, 500va, 1000va, 1500va, 2000va and 3000va units are available.\u003cbr\u003e\u003cbr\u003e\n \n\nThe Powerblok 500va will provide up to 500VA (500 watts) of continuous mains power, and 800VA (800 watts) of short term transient power. This is sufficient to power the majority of domestic Hi Fi systems in use today. However, we recommend that for best performance a considerable margin of latitude is allowed. Therefore we suggest that for stereo systems of up to 100 watts per channel, the Powerblok 500 will be sufficient. If your power amplifiers are greater than 100 watts per channel then either use one Powerblok 500va for each channel or use the Powerblok 1000va (1000VA of continuous power) to run the whole system.","brand":"stoneaudio","offers":[{"title":"Powerblok 150va Pure Balanced Mains Unit","offer_id":57408692355404,"sku":"POWERBLOK150VA","price":382.98,"currency_code":"GBP","in_stock":true},{"title":"Powerblok 250va Pure Balanced Mains Unit","offer_id":57418552738124,"sku":"POWERBLOK250VA","price":499.17,"currency_code":"GBP","in_stock":true},{"title":"Powerblok 500va Pure Balanced Mains Unit","offer_id":57418552770892,"sku":"POWERBLOK500VA","price":570.83,"currency_code":"GBP","in_stock":true},{"title":"Powerblok 1000va Pure Balanced Mains Unit","offer_id":57418552836428,"sku":"POWERBLOK1000VA","price":625.0,"currency_code":"GBP","in_stock":true},{"title":"Powerblok 1500va Pure Balanced Mains Unit","offer_id":57418552901964,"sku":"POWERBLOK1500VA","price":862.5,"currency_code":"GBP","in_stock":true},{"title":"Powerblok 2000va Pure Balanced Mains Unit","offer_id":57418553196876,"sku":"POWERBLOK2000VA","price":1387.5,"currency_code":"GBP","in_stock":true},{"title":"Powerblok 3000va Pure Balanced Mains Unit","offer_id":57418553262412,"sku":"POWERBLOK3000VA","price":1495.83,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/powerblok-pure-balanced-mains-power.jpg?v=1777470932","url":"https:\/\/www.stoneaudio.co.uk\/products\/powerblok-pure-balanced-mains-units","provider":"Stone Audio","version":"1.0","type":"link"}
