Wireless Audio Systems

Here is how the work lines up. Wireless audio in Canada runs the standard senior matrix our mixers and utility-sound technicians deploy through Trew Audio Vancouver and Toronto, William F. White, Sim Digital, Coastal Sound and Audio Plus. The base wireless kit pairs Wisycom MCR42 dual-channel diversity receivers with MTP41S body-pack transmitters for the deepest UHF tuning range, Lectrosonics SRc dual-receivers and SMQv, LMb and DCHT transmitters for the long-running US-studio compatibility, Shure Axient Digital ADX5D portable and ADX1 body-pack for the encrypted-digital VIP and reality-television tier, and Sony DWR-R03D for shoots standardised on the Sony DWX 1.2 GHz ecosystem.

Here is how the picture comes together. Plug-on transmitters cover boom-fed and reporter-mic configurations. IFB packages route to global directors and producers through Lectrosonics IFB, Comtek M-216 and Shure PSM 300 systems, all running on lined up frequencies separate from the dialogue wireless. Lavalier microphones complete the kit. DPA 6060 and 6061 CORE, Sanken COS-11D, Countryman B6 and the larger DPA 4060 and 4061 — concealed through Bubblebee Lav Concealers, Hide-a-Mic, Viviana clips and Rycote Overcover wind protection across costume types.

Here is what we have to work with. Canadian range management is the engineering layer that decides which gear actually works. ISED (Fresh ideas, Science and Economic Development Canada) holds the federal radio-frequency mandate and the post-2019 T-Mobile 600 MHz auction re-allocated the 614 to 698 MHz band away from production wireless toward mobile carriers. This means any kit still tuned in that range needs frequency re-planning or retirement. CRTC governs broadcast TV channel allocation underneath the wireless work, so RF scanning the local TV white space in Toronto, Vancouver, Montreal, Calgary and Halifax happens at scout.

Here is the layout. The 1.9 GHz Wisycom DECT band is the cleaner option in dense urban interference corridors — the TTC subway, the Vancouver SkyTrain, the Montreal Metro and the underground PATH network in downtown Toronto all create enough RF noise that an UHF-only kit struggles on dialogue. TIFF, Hot Docs, Calgary Stampede, Just for Laughs Montreal and CFL Grey Cup weeks create short-term RF density spikes our coordinators flag at the production-meeting stage. CBSA ATA carnet handles global wireless imports. The IATSE 891, 873 and 514 utility-sound assistants on the truck handle wireless rigging under the production sound mixer's department lead.
