Mipro - ACT-343

With the ACT-343, MIPRO offers a quad-channel analogue receiver capable of managing up to four transmitters in parallel. Operating in the UHF band (480 - 934 MHz depending on the region), it uses a 24 MHz narrow-band circuit that effectively reduces intermodulation and increases the number of interference-free channels. This design guarantees clear, stable transmission, even in dense RF environments.

The system incorporates exclusive PiloTone & NoiseLock technology, combined with an RF warning indicator. This allows the squelch level to be adjusted optimally to eliminate interference without the risk of clipping. In terms of compatibility, the ACT-343 offers 7 predefined groups, or 80 preset frequencies, and a user group allowing you to choose up to 8 working channels from the 961 frequencies available. The Auto Scan function and ACT synchronisation make it easy to pair up quickly with transmitters in the corresponding series.

Each channel has its own audio output and switchable gain control (+16, 0, -6 dB XLR balanced, +10, 0, -6 dB 6.35 mm unbalanced). It is also possible to mix the signals from the four channels to a single output, offering great flexibility depending on the configuration. Frequency response ranges from 50 Hz to 18 kHz, with a dynamic range in excess of 106 dBA, guaranteeing faithful reproduction of vocals and instruments.

The ACT-343 adopts a robust 19-inch metal rack format, with a green backlit LCD screen on the front panel. It lights up differently depending on whether the unit is operating or in standby mode, providing an immediate readout of the system's status. At the rear, TNC antenna connectors provide power for MIPRO antenna systems and improve reception range.

Powered by a universal AC 100 - 240 V mains adaptor, the ACT-343 ensures stable operation in all conditions. With its built-in quad-channel, interference management functions and comprehensive connectivity, it is a reliable and versatile HF receiver.
