BA3240
Public Address Power Amplifier
| BA3240 is a integrated amplifier with completed functions,can meet the demand of small public address system separately.
Features:
- Five channels input
INPUT1-INPUT4 can be choosed to be balanced microphone input with low impedance,built-in 24V eidolon power microphone input or line balance input with high impedance.INPUT5 is unbalanced line input with high impedance,INPUT1 is fault channel,can control other channel output
- Balanced rated voltage output with 120V、100V、75V、50V、25V, 4 Ohms rated impedance output and 8Ω/1W monitor output are optionalCan external connect equipments
- Separately volume control for each channels,the total volume control is also available and convenient HF/LF adjust
- Seven sections LED indicators
- Separated areas with Six channels
- The DC 24V interface is available under the urgent situation to provide the power supply when the local voltage has problems
- Power supply is optional for 110V/220V
- Auto power off function under Output short circuit,over loading,overheat protection
