Amplification module WONDOM STA516B 4CH
Class D 4x100W 4Ω @
This Wondom amplifier module is capable of developing up to 4x100W power with a load of 4Ω. It enjoys high efficiency thanks to class T Amplification Technology (up to 90.3% / channel).
Fan & heatsink
The module is equipped with a heatsink surmounted by an automatic-triggered fan in order to avoid overheating that lowers performance and wear the components. This helps to reduce noise and distortion for each channel. The measurements show a THD <1% up to 69W with a 90dB SNR.
Connectors
To facilitate handling, positive RCA input connectors are already mounted on the housing. Similarly, a DC jack 5.5 / 2.5mm and a power supply terminal are also in place. The outputs are accessible directly on the same PCB through imposing pellets, or terminal (also mounted).
The amplifier is compliant parallel BTL and may operate in différants conditions Scheme 4 inputs / 4 outputs.
The amplifier finally has a mute terminal / + 5V to control the powering of the circuit.
