They allow volume control with 4 positions + Off for the MURA 305 model and 11 positions + Off for the MURA 310\/330\/360 models, respectively. The nominal powers they can attenuate range from 2.5W to 30W for 70V lines; from 5W to 60W for 100V lines. Each position entails an attenuation of 5dB to 10dB depending on the model. All models, however, include, in addition to the normal 70-100V audio line, an input for the emergency 70-100V auxiliary line with maximum volume level (in this case, the attenuator does not act but passes the entire signal) and 24V control for switching between the normal and auxiliary lines in case of alarm. MURA Series 3 controls come with a front cover plate (white) and are compatible with BTicino® Matix® 3P plates.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\n\u003cli\u003eOperation on 70V and 100V Constant Voltage Audio Lines\u003c\/li\u003e\n\n\u003cli\u003eCompatible with Standard 503 (108 x 53,5 x 74 mm in-wall box, not supplied)\u003c\/li\u003e\n\n\u003cli\u003e11 Positions (5dB Attenuation) + Off\u003c\/li\u003e\n\n\u003cli\u003e70-100V Auxiliary Line with 24V Relay Control\u003c\/li\u003e\n\n\u003cli\u003eFront Plate (White) Included\u003c\/li\u003e\n\n\u003cli\u003eNominal Power @ 100V: 10W\u003c\/li\u003e\n\n\u003cli\u003eNominal Power @ 70V: 5W\u003c\/li\u003e\n\n\u003cli\u003eControl: 11 Positions + Off\u003c\/li\u003e\n\n\u003cli\u003eAttenuation per Position: 5dB\u003c\/li\u003e\n\n\u003cli\u003eTotal Attenuation: 55dB\u003c\/li\u003e\n\n\u003cli\u003eFlush-mounted Box: Standard 503 - 108 x 53.5 x 74 mm - 4.25 x 2.10 x 2.91 in (Not Included)\u003c\/li\u003e\n\n\u003cli\u003eFront Plate: White (Included)\u003c\/li\u003e\n\n\u003cli\u003eDimensions: 120 x 48 (max.) x 84 mm - 4.72 x 1.89 (max.) x 3.30 in\u003c\/li\u003e\n\n\u003cli\u003eNet Weight: 160 g - 0.35 lbs.\u003c\/li\u003e\n\n\u003cli\u003ePackaging Dimensions: 122 x 65 x 84.5 mm - 4.80 x 2.56 x 3.33 in\u003c\/li\u003e\n\n\u003cli\u003eGross Weight: 190 g - 0.42 lbs.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"HELVIA","offers":[{"title":"Default Title","offer_id":53993204220237,"sku":"J753J","price":15.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/183056-large_default.jpg?v=1779914972","url":"https:\/\/musicdelivery.net\/en\/products\/helvia-mura-310-attenuatore-di-volume-da-10w-per-diffusori-a-70-100v","provider":"Music Delivery","version":"1.0","type":"link"}
