Product Description

Key Features:
Wideband transmission (50MHz) with segmented receiving technology (two independent 25MHz sub-bands).
Each of the two receiver channels supports 100 selectable frequencies.
Standard 1.5U metal chassis with built-in dual-channel receiving circuitry, offering professional-grade durability, heat resistance, and harmonic interference isolation.
Equipped with dual-mute control based on audio tone and RF signal strength, effectively preventing interference from other AV devices.
Features an ACT (Auto Channel Targeting) function: simply press the SET button to automatically and precisely sync the transmitter to the receiver’s operating channel—ensuring error-free operation.
