Power Amplifier AMA-300

Description:

AMA series of PA amplifier used to louden the broadcasting and background music of many occasion. Its output mode is 4-16Ω 70V/110V. And they all have protection setting as short circuit,over loading, bootstrap delay and so on. When outside circuit is short circuit, partial short circuit or over loading, or when impedance is unsuited, it will warn automatically and cut off load output.After solved trouble, it will restore working automatically.AMA series of PA Amplifier have prepositive amplifier, and two channels MIC amplifier. One of MIC1 has the prior function. It has two routes input, one route output, used to record or extend to connect with other power amplifiers.

·Radiator Have a temperature-checking fitting. When it rises to 85℃, the system will send out signal for warning and cut off output automatically, that protect the amplifier from damage.

·When amplifier is over loading, short circuit, or the input signal is too strong,the system will send out warning signal,and cut off load automatically to avoid from damage.

·Fit out one LINE output for recording extend, and connect with other power amplifiers.
