Overview
The 705iR is a lightweight, multipurpose, portable amplification system powered by rechargeable batteries or AC power. It is designed to allow teachers to speak in normal conversational tones and yet be heard clearly by every student in the classroom.
The 705iR comes standard with the LT-70 LightMic™ pendant-style transmitter/ microphone. The system may be used with two microphones accommodating team teaching or student interaction. The second microphone can be an additional LightMic or the HM-70 handheld microphone. Other optional microphones can also be plugged into the LightMic. Contact LightSPEED for assistance in selecting optional microphones.
Ch. A and Ch. B LEDs are hidden by their corresponding volume knobs in this diagram.
