Wisycom MTB40S-UN Ultrasonic Narrowband Plug-on Transmitter

Share

NOTE: This Wisycom MTB40S-UN Ultrasonic Narrowband Plug-On Transmitter is for the B7 option with a frequency range of 470 to 663 MHz.

The Wisycom MTB40S-UN Ultrasonic Narrowband option is an extremely small and light plug-on transmitter designed for professional wireless microphone applications.

The continuous shrinking spectrum has given Wisycom the opportunity to find new solutions that sound pros face related to noise, interference, and reduced working bandwidth.

Wisycom's UN or Ultrasonic Narrowband technology, allows:

• Absolute protection from ultrasonic interference (e.g. next-gen camera range trackers) thanks to a dedicated 70 dB filter
• Narrowband operations to operate using half of the bandwidth and have an extra 50% range
• Switching by SW in "wideband mode", MTB40S-UN mantains full compatibility with all previous Wisycom legacy receivers

Wisycom MTB40S-UN Plug-On Transmitter - Features:

• Provides the widest switching bandwidth available, up 232 MHz range to find the best frequency, anywhere in the world
• Mount the best selective audio filter to avoid any ultrasonic interference
• Advanced linear technology eliminates intermodulation distortion for more robust signal, extended range, and the ability to operate several transmitters within close proximity to each other
• The combination of Narrowband and Linear transmitters allow you to tune every 200kHz and the reduced RX bandwidth gives 3dB uplift in sensitivity
• The transmitter is designed for maximum performance with minimal power consumption which generates less heat–it is always comfortable to wear or operate
• ENC and ENR algorithms for perfect audio in any application almost delay free with 'create' and 'shape' presets for the desired sound
