ACT-818 UHF Digital Wideband Single-Channel Receiver

  • EIA standard metal chassis, with a newly designed color VFD, a rotary control knob and buttons equipped on the front panel. The analog audio output, AES/EBU digital output and MIPRO RCS2.Net interface connectors are equipped on the rear panel. ACT-848 or ACT-828 has a monitor headphone jack, and a Dante or AVB network interface output.
  • Exclusive 72 MHz wideband circuit increases interference-free compatible channels.
  • Digital diversity circuit greatly improves the reception range and the full-range sound quality is not affected by the strength of RF signals or operating distance.
  • Proprietary 256-bit encryption prevents eavesdropping.
  • The DSP audio processor and D/A converter make the sound quality almost the same as the wired microphone.
  • MIPRO Auto Scan and ACT™ function provide the transmitter’s frequency with precise and rapid sync to the receiver.
  • There are 7 preset groups with a total of 224 pre-saved channels. The user-defined group allows users to choose and save up to 16 channels from 2,881 available frequencies.
  • Each channel has separate audio output and 3 switchable output gains, and all is to ensure the microphone operates within proper sensitivity and dynamic range, free from distortion.
  • Optional Dante or AVB digital network interface for digital audio output. (for ACT-828 and ACT-848 only)
  • Optional MIPRO RCS2.Net software connects to MIPRO DVU drive connector and allows real-time network remote-controlling and monitoring up to 64 channels. Additional new FSA software connects to MIPRO DVU drive connector and allows users to calculate interference-free compatible channels and link to the network.
  • Antenna connector provides bias for MIPRO antenna systems to boost reception distance and signal.
  • External AC 100 – 240 V switching power supply ensures stable operation of the system even under drastic voltage change.
  • Pairs with ACT-800H handheld and ACT-800T bodypack transmitter.
  • All are designed and made in Taiwan to ensure high quality and value.
