The MIPRO ACT-5812A is a full-rack, dual-channel true-diversity digital receiver for the 5.8 GHz ISM band. It offers fast setup with Auto Scan and ACT Sync, ultra-low latency in Group B, and 24-bit/48 kHz audio for clean, natural sound. Independent or mixed outputs, OLED control, and antenna cascade ports make it a tidy choice for venues, houses of worship, education, and corporate AV where UHF space is crowded.
