TDA7293 Output impedance?

[Entrant_21]

Hi, im new to amp modding and havnt much experience with how these ICs work, is there any way of changing the output impedance of this poweramp?

Its because im getting a marshall AVT50 combo soon and the output impedance is 4 ohms, I mainly work around 8 so its an inconvenience should I wish to use it for an external cab

Thanks

All solid state amps have impedances much smaller than speaker impedances. The TDA7293 does not much care if it drives 4 or 8 ohms as long as it does not overheat at 4. The power will be smaller with 8 ohms than 4, simply because all solid state amps put out a fixed-size max voltage, and lower speaker impedances pull more current at that fixed voltage. It's just the nature of the beast.

Bottom line, you do not change the AMP impedance for solid state amps like you do tube amps.

Thanks R.G. it makes so much more sense to me now!
