The WMS 45I-A is part of the Perception Wireless 45 range, designed to offer an economical wireless solution without sacrificing the essentials: stability, simplicity, and efficiency. Each component operates over a switchable 30 MHz bandwidth within the UHF range of 500 MHz to 865 MHz, with preselected and fixed frequencies depending on the chosen band.
For whom and for what?
This system is designed for musicians and technicians who want immediate freedom of movement without complex setup. The PT45 transmitter works with most AKG miniature microphones (depending on the instrument), and the included cable allows direct use with guitar or bass, both in rehearsal and on stage.
Simple settings, clear performance
The Band A of this model covers 530.0 to 559.0 MHz (29 MHz) and offers up to 8 selectable carrier frequencies (depending on the band). FM modulation, 10 mW RF power, and an audio bandwidth of 40 Hz to 20 kHz ensure a clean signal, with a signal-to-noise ratio rated at 105 dB. The transmitter is powered by a single AA battery providing approximately 10 hours of autonomy, while the receiver operates with the supplied external power adapter.
