4 Channels Amplifier Factories – Class D power amplifier for professional speaker – Lingjie
4 Channels Amplifier Factories – Class D power amplifier for professional speaker – Lingjie Detail:
Noise-free cooling system
E series amplifier is equipped with a noise-free cooling system, so that the power amplifier can maintain a safe heat resistance level even in a high temperature environment, and it can be operated under unobtrusive background noise. The design of this noiseless cooling system allows even high-power amplifiers can be installed in a noisy and sensitive area without worrying about causing any interference.
● Toroidal transformer power supply
● Class D amplifier module
● High sensitivity CMRR balanced input, enhances noise suppression.
● It can maintain maximum stability under continuous full power operation with 2 ohm load.
● XLR input socket and connection socket.
● Speak ONNI4 input socket.
● There is input sensitivity selection on the rear panel (32dB / 1v / 0.775v).
● There is a connection mode selection on the rear panel (stereo / bridge-parallel).
● There is a power circuit breaker on the rear panel.
● The independent channel on the front panel has temperature, protection and peak-cutting warning lights.
● Independent channel power indicator on the front panel and -5dB / -10dB / -20dB signal indicator.
● Back panel has parallel and bridge indicators.
