Reliable & Interference-free Audio Transmission in Classroom Environment

ACT-101

Specifications

ACT-101 Wireless

Remote Controlled

Microphone System is

ideal for teachers in

multiple classrooms and

comes with IDA

Approved Frequencies.

ACT-101 uses RF wireless technology to

overcome the disadvantages of infrared

wireless microphone systems. With infrared

wireless microphone systems, the

transmitters and receivers must be almost

directly aligned (i.e. able to see each other)

to communicate. When blocked by

common materials, such as people, walls,

plants, etc. the transmission can be lost.

The performance of infrared wireless

microphone system tends to drop off with

longer distances or longer range

transmission. With ACT-101, students

seated at the end of the classroom can

hear clearly, without any loss in

amplification level.

Mipro’s ACT-101 comes with PiloTone, a

squelch circuit function designed by one of

MIPRO's R&D senior engineers. The main

function is to prevent unwanted signal and

sudden bursting noise interference when

the receiver is at stand-by mode. With

PiloTone, both the microphone and

receiver are equipped with built-in sub

audible modulation signals. The receiver

tone squelch opens only when receiving a

signal containing a matching sub audible

tone. Thus, it prevents other signals or

noises from interfering.
