Edifier S2000 Pro amplifier configuration.

[bluesilhouettes]

Hi everyone,
I would open this thread to discuss about Edifier S2000 Pro amplifier configuration.

As per description on Edifier website:

S2000Pro uses three professional digital amplifier chips for producing the best sound in its class. The TAS5754 from Texas Instruments run independently from each other ensuring they do not cause interference while running their respective purpose. The first chip is in control of treble and bass, respectively driving both speakers. The second chip runs strictly the woofers of the S2000Pro using a PBTL (parallel to the bridge) connection which helps build power reserves. The last TAS5754 is dedicated to the amplifier output frequency of 768KHz. With the dedicated chip these speakers are fully optimise to reduce high frequency distortion and local noise.

I don't understand what is the configuration of the 3 amplifier chips ?

And why does they mention about "Digital-to-Analogue and Analogue-to-Digital Converter Signal" 😕 What is the use of DAC ?

The onboard DAC (digital-to-analogue conversion) and ADC (analogue-to-digital conversion) of the S2000Pro has a built-in officially branded Burr-Brown PCM1802 Texas Instrument. The Burr-Brown DAC and ADC uses audio signalling that reaches towards 105dB signal to noise ratio (SNR). The analogue input signal uses traditional HiFi methods that are recognised by WIMA capacitors. This in turn ensures a lower signal loss. As for optical and coaxial inputs, the interface chip, PCM9211 also from Burr-Brown, supports a 24-bit 216-kHz high precision input digital audio signal.

Please explain me if you have time.

What is the use of DAC ?

It sends the Class D amp an analog signal, see attached image from TAS5754 datasheet or if that fails, check out the simplified block diagram on page 1 of the datasheet.

I won't touch the rest of that marketing mess. You could always contact Edifer for clarification.

How does Edifier S2000 Pro sounds like?
