Frequently Asked Questions
Infrared is faster for initial setup but can be less reliable if there's a line of sight issue between the transmitter and receiver; RF syncing is generally more robust in challenging environments.
For a single performer or a duo, WSM isn't critical, but it becomes invaluable for larger bands and complex stage setups to avoid interference.
Sennheiser's Evolution Wireless systems are known for their low latency, typically under 2ms, ensuring a transparent and natural feel for performers.
