Wireless Audio Systems

Here is the layout. Wireless audio in Colombia runs on a stack of Wisycom MCR42 range receivers paired with MTP41S body-pack transmitters, Lectrosonics SRc dual-channel digital-hybrid receivers paired with LMb and DCHT transmitters, and Shure Axient Digital ADX5D plug-on receivers paired with ADX1 body packs. That three-vendor base covers the full senior-feature, telenovela-multi-channel and documentary-redundancy load. Lavalier inventory pairs DPA 6060 and 6061 CORE for top dialogue, Sanken COS-11D for the workhorse telenovela rig, and Countryman B6 for hidden costume work.

Here is how the picture comes together. IFB packages for global directors and producers route through Lectrosonics IFB R1a and Comtek M-216 receivers fed off the bag-mix split. Inventory flows through AudioPlus Bogotá, Sonido Tropical Cartagena and Tres Salida Studios Medellín. Global shoots bring kit in under DIAN ATA carnet and exchange consumables locally. The wireless RF technician role on larger features is filled from the Carlos García and David López production-sound-mixer lineage, with Wisycom Manager and Shure Wireless Workbench used for set up multi-channel deployments and scan-import workflows across location moves.

Here is what we have to work with. Range running is handled through ANE (Agencia Nacional del Espectro) for licensed wireless bands and CRC (formerly ANTV) for the TV-broadcast bands that double as wireless white-space inventory in Colombia. Pre-shoot RF scans are run in Bogotá (where 2,640-metre altitude reduces some FM and VHF range but boosts UHF line-of-sight propagation in Chapinero and Usaquén towers), Medellín (Aburrá Valley reflective bowl shape creates RF multipath that Wisycom range handles cleanly), and Cartagena (the UNESCO Walled City colonial stone produces unusual RF hotspots near the cathedrals).

Here is the layout. Carnaval de Barranquilla in February and FICCI Cartagena film festival in March create extreme RF density windows that drive forward-planning on backup analog frequency reserves. Drone audio sync with Aerocivil-cleared aerial drone units is handled by timecode-locked Tentacle Sync E plus internal recorder slate, since UAEAC off-limits-airspace rules limit RF transmitter output from drone-borne kit. Global director feeds for Netflix Latam, Amazon Studios MGM and HBO Max Latam shoots route through encrypted Lectrosonics Digital Hybrid feeds.
