Product Description
System model: SOYO-EW02
Wireless teaching microphone system for classroom audio/sound solution, consist of wireless microphone transmitter (for teacher), and wireless loudspeaker (for classroom)
1. For teacher, following wireless microphone for options:
Handle type, Headset type, lavalier/lapel type, belt-pack/body-pack type, etc.
2. For classroom, following receiver for options:
A. Wireless speakers version (supporting wall mounted and floor-standing installation)
B. Wireless receivers version (connecting with classroom amplifier/active speakers)
C. Wireless amplifiers version (connecting with classroom passive speakers)
From this demo diagram, we are clear to know:
1. Teacher handling belt type wireless microphones (left side) to talk on class, wireless speaker (right side one) installing on classroom to broadcast teacher's voice, which clearly picked up by each student.
2. Its wireless voice transmission upto 50~60 meters (from headset mic to wireless speaker)
3. This solution also can be dual-channel wireless speaker version, (supporting two microphones talking on class), teacher can choose min portable mic or handle mic, student can handle one pass-around mic to answer questions.
PLUS:
Features of belt-type wireless microphones:
1). Installed in waistband, easy carrying and moving
2). Channel & Volume display and adjusting function.
3). Rechargeable battery or dry battery can be used. (2*AA)
4). Low power consumption, Belt-pack/Body-pack mic an work over 8 hours continually.
4). Transmitter power output: 1mW~100mW as option. (Default power is 100mW)
5). Audio muting function when receiving weak signals or no signals.
6). Capable of being simultaneously used for over 100 classrooms and never crosstalk!
7). Flexible in design and customization logo service available.
Features of wireless loudspeaker (dual-channel)
1). Output Power: 30W; Frequency response: 20Hz - 20kHz;
2). Sensitivity: ≥ -85dBm.
3). Radius of automatic effectively receive: ≥ 15 m;
4). Connection distance automatically matching with microphone: ≥ 5 meters, pairing time within 3 seconds;
5). Host audio speakers with full wireless design.
6). Host speaker owned antenna, no need for additional antenna.
7). Left, right and mixing selector switch to make speaker independent mixing.
8). Wall mounted and handheld design for easy mobility.
9). Supporting wireless and wired audio input, already deployed for classroom audio equipment, audio input port can be shared with host speaker.
10). Supporting two wireless microphones simultaneously, two signals at the same time access without disturbing each other.
