PRODUCT DESCRIPTION

The MIPRO ACT-343 is a quad-channel diversity wireless receiver engineered for professional audio environments that require multiple microphones simultaneously. Its advanced circuitry reduces intermodulation distortion and increases the number of interference-free channels, ensuring stable performance even in complex RF environments.

The green backlit LCD screen automatically lights up to indicate system status (Working / Standby), allowing easy monitoring. The built-in Auto Scan function quickly finds the best available frequency, while the ACT™ sync function ensures fast and precise pairing between transmitters and receiver.

This system includes 2x ACT-32H handheld microphones and 2x ACT-32T bodypack lavalier microphones, providing both handheld and hands-free operation. With independent audio outputs and adjustable gain settings, the ACT-343 ensures optimal audio control across various professional setups.
