Wireless

TD220 microphone using a wireless connection between the microphone and receiver to transmit audio signal. Frequency is synchronized via infrared, PLL synthesized technique, and digital pilot technique to ensure a stable connection.

Anti-Noise

TD220 microphone adopts electronic volume control to allow more precise volume control and an end to the resistance of the potentiometer noise so that the audio would be more clear and enjoyable.

Energy Efficient

TD220 microphone contains a LED display that indicates the system volume, battery, channel of A/B switch, work frequency, receiving distance gear, and the system lock. Despite all of the monitoring, energy consumption is optimized so that not intense energy drainage would occur even in long sessions.

Dual Channel

Dual channel-independent inquiry system for minimizing off frequency. This makes the connection between the microphone and the receiver more stable and with less interference.

Superior Range

TD220 microphone automatically searches for the cleanest available channel without the need to manually changing the channel if there is any interference in the channel or the signal strength is weak.

Simple Setup

Microphone LED display shows a red voltage alarm when the transmitter battery's voltage is low so that users would know when to change the battery or know why the microphone is not functioning.
