100W X 2 Digital Amplifier (PWRDAMP200CH2)

100W X 2 Digital amplifier
1. Characters:
* 2 channel, every channel can output 100W RMS power for 4Ω load.
* Easy using jumper to set the 2 channels into a 200W mono-channel amplifier.
* Integrated high frequency switching power supply (SWPS).
* Both of SWPS and amplifier parts power convention rate efficiency is over 92%.
* Analog signal input interface.
* Direct current feedback topology obtains nice frequency response range from 6Hz ~ 20kHz.
* Using the Pulse Frequency and Wide mixed Modulation (PFWM) technology. Tone is more well than the method only using the Pulse Wide Modulation (PWM).
* S/N better than 85dB.
* Dynamic range better than 100dB.
* Equivalent output impedance lower than 50 MΩ, get high speaker system damp factor.
* High power supply rejection rate, suitable for the worse power supply environment.
* Mute control function.
* No relay start up protection, avoid the relay mechanism failure possible.
* No relay short circuit protection, automatic restart up when the failure disappear.
* 2 LED indicate its channel working states...
* Small size: 115mm X 240mm X 38mm...
