theater and all situations where the smallest size is mandatory


  • The multi-band MTP61 currently has the widest tuning range of any wireless transmitter on the market (470 to 1260 MHz)
  • Monitor & control with Bluetooth via Wisycom Manager software or mobile device apps to adjust parameters in real time
  • Advanced linear technology eliminates intermodulation distortion for more robust signal, extended range, and the ability to operate multiple transmitters in close proximity to each other without needing an intermod frequency plan
  • Embedded recorder to record directly on the internal 64 GB micro SD card and integrated Linear Time Code decoding
  • DSP based signal processing allows easy switching between wide and narrow band operation
  • ENS compander for a totally clear sound
  • Powering with Lithium-ion battery Model CS-BCE10 (Part No. CGA-S008E 3.7V, 1050 mAh, 3.9Wh Cameron Sino)
  • Bluetooth interface and mobile app allows full control from mobile or tablet
  • Integrated low-pass audio filter eliminates ultrasonic interference from devices such as focus pullers
  • Front panel buttons to quickly enter menu thanks to its multiple shortcut combinations
