Taking Covid-19 seriously.
Wear a mask, and wash your hands whenever possible. I always keep hand sanitizer at the sound cart.
For those scenes when lavs are an absolute must, I use the Zaxcom ZMT-X transmitter. In addition to being an excellent sounding, long distance transmitter, these devices record ONTO the transmitter, meaning less monitoring and maintenance is required. Most importantly, they feature a BT100 battery with up to 12 hours battery, and power and frequency can be changed remotely from the mixer. This means talent can stay wired up all day with significantly reduced contact from the sound mixer.
