Mipro - Pack ACT-545 + ACT-500T Batterie Lithium (lot de 4)
The Mipro ACT-545 + 4 ACT-500T beltpack meets the needs of configurations requiring reliable management of several HF microphones on a single installation. The ACT-545 quad-channel receiver covers a wide UHF 480-934 MHz frequency range with a narrow 24 MHz band and true diversity reception, helping to maintain a stable signal for up to four simultaneous transmitters. It features fast frequency selection via Auto Scan and ACT™ synchronisation, as well as XLR and jack outputs with adjustable levels for easier integration into the audio system. ACT-500T beltpack transmitters are compact, lightweight and designed to accommodate tie or headband microphones. Their backlit LCD display makes it easy to keep track of settings, and ACT™ synchronisation ensures smooth pairing with the receiver. Each bodypack accepts one lithium-ion battery or two AA batteries, with direct charging via USB-C, so you can prepare for procedures without power constraints.
Composition of the package
Presentation
Thanks to the Auto Scan and ACT functions, frequency allocation is a breeze, even in environments already loaded with signals. PiloTone and NoiseLock systems help maintain clean transmission, while XLR and jack outputs with switchable levels make it easy to integrate into any type of console or fixed installation.
ACT-500T beltpack transmitters complete the package with a practical, flexible approach. Compatible with Mipro tie and headset microphones, they offer several levels of audio sensitivity to suit the voice, microphone placement or context of use. ACT synchronisation ensures rapid pairing with the receiver, limiting manual adjustments.
Their dual power supply - rechargeable lithium-ion battery or AA batteries - means you can look forward to long sessions with peace of mind, recharging directly via USB-C or via dedicated docking stations.
To get the most out of this pack, simply run a frequency scan before each session, adapt the RF power according to the coverage area and lock the bodypack settings to prevent inadvertent manipulation.
