Product Features:

1. The AMX series adopts the classic pulse width modulation amplifier circuit, which makes the whole machine have low static power consumption, abundant dynamic energy, and an efficiency of up to 90%.

2. High-quality toroidal transformer and HIFI standard components make the sound performance more perfect.

3. Real-time output signal measurement and processing to obtain the actual instantaneous output power: collect all data wells and compare them with the effective stored energy and effective power obtained from the power supply to avoid system deviations, such as overvoltage, overcurrent, short circuit, etc.

4. The large display on the front panel shows gain, voltage, fan speed, peak shaving, protection, mode status (e.g. bridged, parallel, stereo) and temperature of the AB channel.


Suitable for: KTV, bar, slow shake bar, conference room, stadium, multi-functional lecture hall, theater and so on.
