Frequently asked questions
Can I use both of these together?
Yes, but for different stages of a signal chain. The C391 B is a wired condenser microphone for capturing sound; the AB4000EW boosts wireless antenna signals. They would never be used on the same signal path—the C391 B feeds an audio interface or mixer, while the AB4000EW sits between wireless antennas and a receiver to improve RF reception.
Which one is better for live performance?
The C391 B is suitable for live vocals and acoustic instruments if you use a wired connection, offering excellent feedback rejection and clarity. The AB4000EW solves a different live problem—improving wireless microphone reception in large venues or outdoor spaces where signal dropout occurs. If you are using wireless microphones, the AB4000EW is essential; if you use wired mics, the C391 B excels.
What is the price difference, and which offers better value?
Both are budget-tier products. Value depends on your need: the C391 B is essential for anyone recording acoustic sources with professional quality at home or in studio. The AB4000EW is only valuable if you operate wireless systems; without wireless mics, it serves no purpose.
Do I need any special cables or connectors for either?
The C391 B connects via a standard balanced XLR 3-pin cable and requires 9–52 V phantom power from a mixer or interface. The AB4000EW uses BNC connectors to link antennas and wireless receivers; it is powered remotely through the antenna cable and includes an in-line LED indicator.
