Wireless Audio Systems

Here is how this works in practice. Spain's wireless-audio inventory is structured around CNMC (Comisión Nacional de los Mercados y la Competencia) range coordination. CNMC manages the post-Audio-Visual Communication Service Act 600 MHz re-allocation following the European Digital Dividend. And Spain's licensed wireless production bands cluster around the 470-694 MHz UHF window plus the 1492-1518 MHz L-band fallback for dense-urban work. The flagship feature-rig inventory is Wisycom MCR42 dual-channel range receivers paired with MTP41S transmitters (the senior Almodóvar-bench standard since the late 2010s).

Here is the short of it. Lectrosonics SRc dual-channel + LMb belt-pack + DCHT digital handheld for the Hollywood-inbound features (Indiana Jones Dial of Destiny, Pirates of the Caribbean Cádiz, Solo Star Wars Story Fuerteventura, Wonder Woman 1984). And Shure Axient Digital ADX5D dual-channel + ADX1 belt-pack for the broadcast-end work at RTVE, Atresmedia, Mediaset and Movistar+ studios. Lavalier capsule rotation runs Sanken COS-11D, DPA 6060 + 6061, Countryman B6 and DPA 4071 depending on talent rigging needs.

Here is the breakdown. Engagements begin with a CNMC RF scan at every new location and a daily frequency plan re-confirmed against the local range environment. Madrid + Barcelona dense-urban work carries the highest RF coordination load — Wizink Center Madrid, Palau Sant Jordi Barcelona. Plaza de Toros Las Ventas, Plaza de España Sevilla. Mediapro Studios Sant Joan Despí, Pinewood Iberia. Eyeworks Madrid and RTVE Prado del Rey stages each need pre-roll scans for white-space discovery and frequency-clearance against the broadcast-licensed local mux.

Here is what that looks like on the ground. Festival-week density (Mad Cool Festival August, Primavera Sound June, Sónar Festival June, FIB Benicàssim July) creates concentrated multi-production RF-density windows where the Wisycom DECT 1.9 GHz fallback and the L-band redundancy slot become key. Heritage zones (Alhambra Granada, Alcázar Sevilla, Mezquita Córdoba, Toledo, Salamanca) carry low-power-only protocols that the wireless wrangler handles inside the production-sound contract. Canary Islands trade-wind environments (Fuerteventura, Lanzarote) need range-receiver protocols against multipath fading on volcanic terrain. Bilingual ES/EN RF-coordination is standard. NAV-equivalent ATA carnet through AEAT clears imported wireless inventory cleanly through Madrid-Barajas customs.
