International orders*The AKG AB4000 is an in-line antenna signal amplifier specifically designed to boost wireless microphone Radio Frequency (RF) signal. Receiver antennas are often positioned at far proximity to the actual receiver in sound reinforcement applications, causing significant loss in RF signal gain. RF signal strength is restored when the AB4000 is inserted in-line between an antenna and wireless microphone receiver.
