They allow for volume control with, respectively, 4 positions + Off for the MURA 305 model and 11 positions + Off for the MURA 310\/330\/360 models. The nominal power they can attenuate ranges from 2.5W to 30W for 70V lines; from 5W to 60W for 100V lines. Each position involves an attenuation of 5dB to 10dB depending on the model. All models, however, include, in addition to the standard 70-100V audio line, an input for an auxiliary 70-100V emergency line with maximum volume level (the attenuator in this case does not act but passes the entire signal) and 24V control for switching between normal and auxiliary line 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\u003eAuxiliary 70-100V Line with 24V Relay Control\u003c\/li\u003e\n\n\u003cli\u003eFront Plate (White) Included\u003c\/li\u003e\n\n\u003cli\u003eRated Power @ 100V: 30W\u003c\/li\u003e\n\n\u003cli\u003eRated Power @ 70V: 15W\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\u003eRecessed 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: 170 g - 0.37 lbs.\u003c\/li\u003e\n\n\u003cli\u003ePacking 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: 200 g - 0.44 lbs.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"HELVIA","offers":[{"title":"Default Title","offer_id":53993204613453,"sku":"J754J","price":19.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/183125-large_default.jpg?v=1779914980","url":"https:\/\/musicdelivery.net\/en\/products\/helvia-mura-330-attenuatore-di-volume-da-30w-per-diffusori-a-70-100v","provider":"Music Delivery","version":"1.0","type":"link"}
