The WMS420 wireless microphone system provides a highly flexible as well as easy to use solution. The ultra high
frequency system is set up within seconds and is equally suitable on stage as well as in locations where a single- or multi
channel solution is needed.
The entire WMS420 wireless system consists of the SR420 stationary receiver, HT420 handheld transmitter and the
PT420 pocket transmitter. The HT420 handheld transmitter is available with the patented D5 dynamic microphone
acoustics. This capsule guarantees maximum rejection against feedback, reduced handling noise and the famous AKG
sound. Both transmitters are shipped with charging contacts that enable the use of rechargeable batteries. Moreover the
transmitters offer exceptional eight hours of operation time from a single AA size battery, which dramatically reduces the
operating costs in day-to-day use.
The detachable receiver antennas allow the use of professional accessories, such as antenna splitters and remote
mounted directional antennas for multi channel systems. The WMS420 series includes three different bodypack sets. The
head-worn set includes the high performance C555 L condenser microphone. The presenter set includes the professional
C417 L lavalier microphone. The guitar set includes an instrument cable. With the AKG WMS420 system up to eight
channels can be run simultaneously.
