UHF
72
VFD
- EIA standard metal chassis, with a newly designed color VFD, monitor headphone jack, a rotary control knob and buttons equipped on the front panel. The analog audio output, AES/EBU digital output, Dante or AVB network interface output and MIPRO RCS2.Net interface connectors are equipped on the rear panel.
- 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.
- Optional MIPRO Wireless Console computer monitoring software offers frequency analysis and configuration, along with monitoring of all channels and interference signals in the environment.
- 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.
