The MIPRO's ACT52H is a rugged wireless microphone transmitter with unique multi-layered steel grilles that protect the capsule from impact, anti-roll, and pop noise while still providing transparent sound clarity. ACT52H has interchangeable capsule modules with quality condenser or dynamic choices, and the upper grille can be easily removed for cleaning and hygienic purposes. It also has a silent lockable on/off switch (proprietary) to prevent power-off during performance and the LCD shows working channel, battery status indicator, and error code messages.
