Agreed.If you add my 234 degrees to Jim's 126 degrees, you get 360 degrees
Now how can I synchronize this two waves?
This is two amplifiers and i have to do it with pre-amp or something like that.
Hm. Shouldn't he be able to shift one of the signals on screen using this control;There is no simple solution to shift a signal over a given degree quantity ...
For simple phase-shift circuits, the phase will vary with frequency.So I think I need a phase-shifter circuit
There is an audio waveform comes from a TV (Vpp is 230mv) and goes to two separate stereo amplifiers.
As I mentioned and you kindly help me to find the phase-shift is 126 degree "IN SPEAKER OUT" compare to each other.
The issue is to make this two in same phase. So I think I need a phase-shifter circuit for at least one of them it means , one amplifier will directly connect from TV and other one will give the signal from the "phase-shifter circuit" and with a potentiometer I would make them is same phase.
The reason of this is:
I had 4 channel amplifier before and I don't have it now ( have to replaced with 2 amps) before that I feel the bass of musics really sync , clear and amazing ( I can not tell it by words) but with new system I feel bass has cut or weak or distortion and it is not good at all.
and if it's class D, is it using DSP? the shown phase shift could be the processing delay of a DSP chip.Is one of the amplifiers a class-D one perhaps?.
For simple phase-shift circuits, the phase will vary with frequency.
Over what frequency do you need to shift the phase and how much does the amplifier phase-shift change over that range?
