At MD Audiovisual Services we design the projects minimizing the visual impact in certain environments. A good example is the imposing Basilica of Santa María del Mar. A thousand-year-old setting, a great example of Catalan Gothic, which requires an audiovisual treatment that respects its architecture. An aspect that we value when we buy new AV material. The current technology offers quality with elegance and a great design able to blend into the environment as is the case with our RGBA LED Par Quad-4 lighting. Small focus with a powerful battery of long autonomy and can be operated by remote control, avoiding all types of cables. Its reduced size (145 x 138 x 191 mm), allows to place them at the foot of columns, being hidden from the public and minimizing the visual impact.
