BNK BK 25 Professional Microphone

Key Features

• Dual Wireless Microphones
  Comes with two handheld UHF wireless microphones, so you can have two speakers/singers using the system simultaneously

• Frequency / Audio Quality

  • Frequency response: about 50 Hz to 15 kHz, giving you a decent range for clear vocals.

  • Signal‑to‑Noise Ratio (SNR): greater than 70 dB, meaning background hiss is relatively low.

  • Total Harmonic Distortion (THD): less than 0.5%, so distortion at normal volumes is small.

• Range & Transmission
  The wireless system works up to ~100 meters (line of sight) in UHF band — good for venues like halls or stages.

• Power & Battery

  • Each microphone uses AA batteries (alkaline).

  • Battery life is around 8 hours under typical use.

• Build & Design

  • Casing: durable plastic housing for both mics and receiver.

  • Receiver includes balanced XLR and unbalanced 1/4″ TS outputs, so it can be connected to amplifiers, mixers or PA systems.

  • Receiver has controls for digital volume, and likely indicators for signal strength / battery etc.

• Additional Features

  • Dual‑channel receiver (handles both mics independently).

  • “Jamming filter” / interference reduction to help avoid RF interference.

  • Multiple frequency groups (8 groups) so you can choose different channels/frequencies if needed.
