Hi,
I am looking to understand the delay caused by tripath chips... I am looking from the point of view of biamping. If you were to biamp with a class a which is pretty much real time, wonder how much the difference would it be?
Has anyone ever measured, say with an impulse input, what the output delay would be. 10ms , 100ms?
Thanks in advance.

Hi.
It doesn't have a dsp per se however, the conversion from voltage to pulse width is done by a signal processor of sorts. At least this is what the datasheet calls it. I would imagine it has a fairly sophisticated system and not just a triangle wave generator. I would imagine it to be sort of control system based on a microcontroller based on PID or other control algorithm. Wonder how much delay that will introduce.

There is no digital signal processing in a Tripath amp hence there cannot by definition be any delay. That's not to say there isn't any as signal path may be significantly longer than in a class A amp but we're talking in the microseconds range not milliseconds.
As far as I've understood the Tripath patents all signal processing is analogue, and is feed-forward to the inverting input of the input op-amp from the feedback loop, so that doesn't technically have any delay either.

There could be a phase shift, which is arguably a time delay ... This would be induced by the input/output filters.
In what way do you experience this delay or otherwise unexpected side effect?
