Non-amplified 1 channel infrared microphone receiver

The VoiceLink™ I system will expand your multi-media sound system to include voice reinforcement via an infrared wireless microphone.

The VoiceLink™ I is a preamp-only receiver and is designed to be plugged into an existing power amplifier or the input of a multi-media sound system.

With a VoiceLink™ I infrared wireless microphone system, the teacher’s voice will be clearly heard throughout the room with ease.

And the auxiliary input on the front panel allows the input of a smart phone, computer, or DVD to supplement the instructional program.
