In the PQ-707, Ultra-Linear Noise Dissipation is taken even further with a wider-bandwidth (8kHz to 1GHz) Differential-Mode filter.\u003c\/p\u003e\n\u003cp\u003eIn addition, the PQ-707 includes Transient Power Correction (TPC).\u003c\/p\u003e\n\u003cp\u003eTPC provides a current reservoir of up to 45 amps peak on-demand power for any amplifier (up to 25mS), supplying the low-impedance current the amp needs to produce thrilling dynamic contrasts, bass extension, and control.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProtection Assured\u003c\/strong\u003e\u003cbr\/\u003e\nAll models feature Non-Sacrificial Surge Protection and Extreme-Voltage Automatic Shutdown at 140VAC.\u003c\/p\u003e\n\u003cp\u003eIf more than 140VAC is present on the incoming AC line for more than a quarter of a second, the circuit will instantly open a high-current relay that will disengage the AC power from all the PowerQuest AC outlets, activating the red front-panel LED “Overvoltage Protection” warning indicator. Once the event has passed, or the building wiring fault has been corrected, the circuit will automatically re-engage.\u003c\/p\u003e\n\u003cp\u003eTake comfort in knowing that valuable gear is well protected.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e2m RF-Noise Dissipating cable \u003cstrong\u003ePQ-416\u003c\/strong\u003e with Semi-Solid Concentric Conductors using Long-Grain Copper (10amps @240V) included.\u003c\/p\u003e","brand":"audioquest","offers":[{"title":"Default Title","offer_id":52457491988746,"sku":"147534","price":599.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0717\/5340\/0586\/files\/img147534_78288.jpg?v=1769459725","url":"https:\/\/hifi.shop\/en\/products\/audioquest-powerquest-pq-303","provider":"Hifi \u0026 Friends GmbH","version":"1.0","type":"link"}
