CD amplifier
1. MIC input,volume autocephaly adjust
2. Circuit input,volume autocephaly adjust
3. MIC 3 and alarm with priority function, when they work will automatically attenuation other signals. When MIC 3 and alarm cessation working , other signals automatic restored
4. 4Ω-16ΩFixed-impedance output
5. 70V or 120V optional pressure output
