AKG WMS 420 INSTRUMENTAL Wireless instrument set

Free yourself! for live sound, presentations and installations 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 acoustic. 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 C555L condenser microphone. The presenter set includes the professional C417L lavalier microphone. The guitar set includes an instrument cable. With the AKG WMS420 system up to eight channels can be run simultaneously.

Due to the changed situation in the area of general frequency allocations for the operation of wireless systems starting in 2015, LD Systems decided to develop the even more flexible and highly professional WIN 42 wireless system.

With its outstanding audio quality, the LD Systems WIN 42 UHF system offers numerous potential applications for live performances and permanent installations. The working UHF frequency range is 734 MHz to 776 MHz. Both the handheld microphone and belt pack transmitter versions provide any vocalist, speaker or instrumentalist optimal transmission of his or her performance with the greatest possible freedom of movement. By means of a threaded connection, the microphone head of the handheld transmitter can be swapped quickly and easily (dynamic and condenser capsules).

The system has more than 1680 freely selectable frequencies and thus makes it possible to operate up to 20 systems simultaneously. The "channel scan" function assists you in finding and tuning to a transmission frequency without interference. This frequency is then transmitted simply and conveniently from receiver to transmitter via an infrared link. The transmitting power is adjustable in 3 stages (10, 30, 50 mW) directly on the microphone, permitting adaptation to any environment.

The half-rack True Diversity receiver houses numerous system features, for example, a transmitter battery status indicator on the receiver display, an indicator for the (transmitter) "Mute On/Off" function on the receiver display, 4 EQ presets that are switchable at the receiver, and much more. A highly professional system embodying the outstanding value-for-money that is so typical for LD Systems.
