AKG WMS400/HT/D880 Wireless Handheld Microphone System |
Highly flexible wireless system, ready for immediate use and scalable for demanding applications.
The WMS 400 provides cost-efficient, high-performance solutions for situations where several radio mics will be used simultaneously, including gigs at small clubs, small stages, or regional events. Using several single-channel systems has its limitations and may simply be too much for the available radio band.
Based on the technology of and user input on the revolutionary WMS 4000 wireless system, the SR 400 provides a number of features that make setting up and operating a wireless system as easy as never before. Up to 12 channels can be used simultaneously within the same subband and even large systems will work smoothly in environments hostile to RF transmission.
The WMS 400 makes setting up a professional wireless system of this class easier than ever before. In Auto Setup mode, the receiver will scan the available bands, find an interference- free channel, and transmit the related frequency data to the assigned transmitter via infrared. This technique significantly reduces the time it takes to set up a multichannel system. A Rehearsal function identifying dead spots, a programmable display clearly indicating all important system parameters, two-color display backlighting warning the user of critical conditions from a distance, and a transmitter battery status display on the receiver enhance reliability and add to ease of use.
Being compatible with professional WMS 4000 antenna splitters, power supplies, and high quality antennas, the WMS 400 enables you to set up highly complex wireless systems.
Many innovative features enhance both system reliability and user friendliness. The LC display indicates all important system data at a glance, including the frequency you selected from the factory presets (country, group, channel), transmitter battery capacity, a warning when battery capacity is low, as well as the current transmission mode.
Transmitter/receiver:
The situation with a transmitter and a receiver can be compared to the transmission of a signal between a radio station and a radio set. When we encounter problems with reception, we will either reposition the antenna, or look for the station on another frequency. The WMS 400 allows 12 channels to be used simultaneously and provides 1200 selectable frequencies for reliable transmission. |

Once you have set a frequency on the receiver, an infrared transmission link will feed the related data to the assigned transmitter within seconds, making the setting up of large multichannel systems child's play. The HT 400 handheld transmitter is available with a dynamic or a condenser microphone element.
