ICEpower 125ASX2 in BTL mode using DSP

[ollieb1234]

Hi I have an ICEpower 125ASX2 and want to set it up in BLT mode. I have seen in the documentation that the signal to channel 1 needs to be inverted. I am powering it using a ADAU1701 AMP2 dsp board that outputs RCA and works fine under normal operation.

Can I set the DSP to make one of the RCA Inputs 180deg out of phase and use for ch1 input while in BLT mode? (I would also mix the L/R to mono in the DSP
Thanks for your help!

Anyone got any idea on this please

Hi thanks for your reply. The bit I'm worried about is all the posts online say it requires balanced connections and my RCA output would be unbalanced

Does anyone know if this might be an issue, I dont really understand the difference between the two or how the amp uses them
Thanks

The SigmaStudio signal invert will do exactly what you want. The only drawback is you will need two DACs, one for the normal signal (goes to Vin channel 2) and one for the inverted signal (goes to Vin channel 1).
