The vandal-proof sound projector, C86/20-EN, features a grey aluminium housing and a yellow-galvanised front grille, tropicalised and stove-enamelled. Due to the particularly tough and sealed design, class of protection IP65, this range is especially suitable for use in particularly difficult environmental conditions.
They have wide-band loudspeakers featuring a high level of acoustic efficiency for excellent reproduction of both voice and music. Each unit is supplied with a swivelling fixing bracket that slides along the housing and a transformer for 100/70/50 V constant-voltage lines with an output power adjustable to 20-10-5 W. |
