Frequently asked questions
Can I use both products together in a wireless system?
Yes. The GN50 ESP is a microphone module that feeds audio into a wireless transmitter, while the AB4000EW boosts the antenna signal returning to the receiver. They solve different parts of the wireless chain and are often used together in touring rigs.
What skill level do I need to install these?
The GN50 ESP requires basic familiarity with gooseneck mounting and XLR connectors—suitable for intermediate users. The AB4000EW is even simpler: inline installation with no configuration needed beyond flipping cable-length switches, making it accessible to anyone managing wireless systems.
Does the GN50 ESP work with non-AKG wireless systems?
The GN50 ESP outputs balanced XLR 3-pin and is designed for AKG wireless transmitters, but any wireless system accepting standard XLR input at 2000 Ohms impedance will accept it. Check your transmitter's input spec before purchase.
How much does the AB4000EW actually improve range?
The 17 dB gain compensates for 3.5–17.5 dB of cable and environmental losses, effectively doubling or tripling usable range depending on your specific cable length and venue RF conditions. Results vary with antenna placement and RF obstacles.
