They allow control with, respectively, 4 positions+Off for the MURA 205 model and 11 positions+Off for the MURA 210\/230\/260 models. The nominal powers they can attenuate range from 2.5W to 30W for 70V lines; from 5W to 60W for 100V lines. Each position results in an attenuation of 5dB to 10dB depending on the model. The MURA 210\/230\/260 models include, in addition to the normal 70-100V audio line, an input for the 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 lines in case of alarm. MURA Series 2 controls include the front cover plate (white) and the wall box.\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\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\u003eRecessed Box Included\u003c\/li\u003e\n\n\u003cli\u003eNominal Power @ 100V: 30W\u003c\/li\u003e\n\n\u003cli\u003eNominal 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: 80 x 80 x 48 mm (Included) - 3.15 x 3.15 x 1.89 in\u003c\/li\u003e\n\n\u003cli\u003eFront Plate: White (Included)\u003c\/li\u003e\n\n\u003cli\u003eDimensions: 82 x 43 (max.) x 82 mm - 3.23 x 1.7 (max.) x 3.23 in\u003c\/li\u003e\n\n\u003cli\u003eNet Weight: 170 g - 0.37 lbs.\u003c\/li\u003e\n\n\u003cli\u003ePacking Dimensions: 87 x 45 x 87 mm - 3.4 x 1.8 x 3.4 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":53993204547917,"sku":"J758J","price":18.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/183113-large_default.jpg?v=1779914978","url":"https:\/\/musicdelivery.net\/en\/products\/helvia-mura-230-attenuatore-di-volume-da-30w-per-diffusori-a-70-100v","provider":"Music Delivery","version":"1.0","type":"link"}
