Wireless lavalier microphone system with body-worn transmitter and separate receiver. Operates at 24-bit/48 kHz digitization, achieving 120 dB dynamic range with 6–8 h battery life.
Professional wireless lav systems operate with 24-bit/48-kHz digitization and achieve a dynamic range of up to 120 dB. The transmission power is typically 10-50 mW, and latency in digital systems ranges from 2-4 ms. Diversity receivers use two antennas to minimize dropouts caused by multipath propagation. Modern true diversity systems continuously switch between signal paths. Compander systems compress the signal at the transmitter and expand it at the receiver for noise reduction. Battery life is 6-8 hours with lithium-ion batteries.
The first commercial wireless lav system for film was developed by Vega in 1976 with the analog System 55. Sennheiser introduced the evolution series in 1982, which combined FM modulation with companding. The transition to digital systems began in 2009 with Audio-Technica's System 10, followed by Sennheiser's AVX (2013) and Shure's Axient Digital (2016). The shift from analog UHF to 2.4 GHz technology occurred from 2015 onwards due to frequency scarcity caused by LTE expansion.
On "1917," sound mixer Oliver Tarney used over 20 Sennheiser G4 wireless lav systems simultaneously for the one-shot sequences, as cable deployment was impossible. In action films like "Mission: Impossible," wireless lav systems enable sound recording during stunts without the risk of cable breakage. The workflow includes frequency scanning before shooting begins, timecode synchronization with the camera, and continuous monitoring for dropouts. Disadvantages include battery consumption, radio interference in urban areas, and potential latency issues in playback scenes.
Wireless lav systems differ from wired lavaliers by offering freedom of movement at a higher technical cost. Recorders like the Zaxcom ZMT4 combine a wireless lav system and recording in a bodypack. Modern alternatives include the Deity Connect series or Røde Wireless Go with integrated recording. UHF systems offer greater range, while 2.4 GHz systems are license-free but more susceptible to interference. For exterior shoots with many actors, hybrid setups of wireless and wired systems are used.
Ich plane meine Kamerabewegungen so, dass der Toningenieur mit seinen Funkstrecken-Empfängern nah genug bleibt – bei Steadicam-Fahrten über 50 Meter koordiniere ich vorher die Reichweite. Die Bodypack-Versteckung bespreche ich mit der Kostümabteilung, da sichtbare Sender oder Kabelführung meine Kadrage einschränken können.
Funkstrecken geben mir die Freiheit, Schauspieler in großen Räumen oder bei komplexen Choreografien zu führen, ohne dass Kabel die Performance stören. Ich kann spontane Improvisationen zulassen, da der Ton flexibel mitgeht – allerdings muss ich bei emotionalen Szenen auf das psychologische Element der "Verkabelung" verzichten, das manche Darsteller zur Konzentration brauchen.
Pro Funkstrecke kalkuliere ich 150-400€ Tagesmiete plus 50€ für Ersatzbatterien, bei größeren Cast-Ensembles wird das schnell zur Kostenfalle. Der Zeitaufwand für Setup und Frequenzkoordination verlängert die Rüstzeit um 15-30 Minuten täglich, dafür spare ich Aufbauzeit für Kabelverlegung bei Locationwechseln.
