I notice this chip can do PBTL ,but in 8ohm mono, it's the same power with stereo.

For mono 8 ohm, can this work with Full Bridge? meaning Double BTL into 600W @ 8ohm ?
When set board as PBTL mode,2ohm or 4ohm /8ohm loader all ok,full range mode ,Damp Factor will higher in this condition.excellent powerful bass right now.

4ohm loader can get 600W power ,8ohm can not realize even if PBTL mode,due to PVDD is only 50V .you can find this parameter in TAS5630 datasheet.

in that case, tda895x chips are better in BTL mode for 8 ohm speakers.

TDA8954 BTL can have 400W++ in 8ohm :

Features list:
Power supply: 90-265vac 50 or 60Hz
Sourece: Coxial Spdif/USB/2 analog or Optical Spdif/USB/2 analog
Output: 1x200W/4ohm(subwoofer)+2x50W/8ohm or 4ohm (stereo)
or 1x100W/8ohm(subwoofer)+1x100W/4ohm(mid range)+1x50W(tweeter)
Low cut switch:70Hz(on/off switch on rear)
Sub Franquency: 50Hz-150Hz

Core chip:
DSP:ADAU1701
AMP:TAS5630
USB:PCM2707

Take Some Pics here:
This is a very interesting product, some questions if I may.

How would you manage a pair of these amps used for 3 way active speakers and a digital input? Am I right in thinking the stereo digital input would be supplied to (say) the right channel amp with the right channel processed by onboard DSP to drive three analogue outputs to the power amp section?

How would the left channel signal be then sent to the second amplifier? Is there a digital out provided for this to link them?

For this 3 way speaker use, is the Sigma Software provided so that we can have full control of crossover points, types and slopes?

How does the volume control work, digital on the DSP or or analogue between DSP and power amp or something else? Does it control all three channels or just two?

And can you give us a rough idea of cost please?

Hi,

I am very interested in your DSP Design - any plans only to offer the Inputboard with DSP without Amp stage?

regards
Alan

IDEA: what about a 4 chips -aka ways- "simple" (means without DSP) amp based on TDA8950 ?

It could be used both for multiamplification and Home Theatre applications too !

...and could be easily (with a rear switch, for example) bridged into a 2.0 very high power amp !

Do you know the DARED DV-6C ?

About the switch: something like this: Click the image to open in full size.

Positions/configurations:
  1. Mono: all chips bridged togheter
  2. Stereo: chips bridged in couples (2+2)
  3. 2.1: 2 chips bridged togheter and 2 self bridged
  4. 4.0: 4 chips self bridged
  5. 5.0: 2 chips bridged togheter and 2 unbridged
  6. 6.1: 1 chip self bridged and 3 unbridged
  7. 8.0: all chips unbridged
