The MIPRO ACT-32HR is a wireless handheld microphone transmitter that can remotely control the volume on the MIPRO MA-708 and MA-808 portable wireless PA systems (both sold separately). It comes with MIPRO's MU-90 ECM Supercardioid mic capsule module, and offers mic capsule interchangeability with other compatible MIPRO microphone capsules (see list below). It also features automatic frequency synchronization with the receiver via MIPRO's patented ACT™ function.

Additional MIPRO Compatible Mic Capsule Modules (all sold separately):

  • MU-80 (ECM, Supercardioid) 
  • MU-70 (ECM, Cardioid)
  • MU-59 (Dynamic, Supercardioid)
  • MU-39 (Dynamic, Supercardioid)

MIPRO ACT-32HR Features:

  • Robust, lightweight plastic housing.
  • Interchangeable capsule module with premium condenser or dynamic options for fast, easy changeovers (Note: additional capsule modules sold separately).
  • Premium condenser capsules exhibit high fidelity, wide dynamic range, fast transient responses, good feedback rejection, accurate sound image characteristics, transparent sound quality, and withstand maximum SPL (Note: additional capsule modules sold separately).
  • Reversible end-cap allows power on/off switch being locked to avoid accidental power-off during performance.
  • Impact-resistant battery compartment holds 2 AA batteries.
  • Backlit LCD displays various parameters and status.
  • Stable PLL circuits. Automatically synchronized with the receiver's frequency using MIPRO's patented ACT function.
