PA Systems — Public Address · 88 Series

This product is a brand-new digital wireless microphone with a novel architecture. It adopts digital U-band transmission technology and pi/4-DQPSK modulation, resulting in a low bit error rate and stable transmission. Compared with most U-band analog modulation products in the industry, it has advantages such as strong anti-interference capability, ID code pilot technology to prevent crosstalk, and frequency sweeping to avoid interference.

Features

  • Easily obtain current device information via the handheld microphone display .
  • The handheld microphone features a one-click mute function to prevent accidental touches, making it highly practical.
  • The handheld microphone has adjustable transmission power, which can be adjusted as needed.
  • The handheld microphone automatically mutes after 8 seconds of inactivity and automatically shuts down after 8 minutes.
  • The handheld microphone supports AA batteries (compatible with NiMH/alkaline/lithium batteries) for use in various scenarios.
  • The handheld microphone features a low-power design, allowing for continuous speaking time of over 10 hours.
  • When the microphone is dropped or thrown, it automatically mutes itself in milliseconds to avoid impact noise.
  • The handheld microphone supports both Type-C interface charging and charging dock charging, making it more convenient and environmentally friendly.
  • The handheld microphone features an ergonomic design with a rounded shape that fits the curves of the hand, providing a comfortable grip.
  • It adopts digital U-band transmission technology and pi/4-DQPSK modulation, which has strong anti-interference ability, low bit error rate and stable transmission .
  • It features audio encryption; when enabled, the microphone and receiver use a unique ID code pilot encryption technology to prevent crosstalk between devices.
