Hello,
I'm experiencing a peculiar issue with my audio setup and would appreciate any insights or suggestions you might have regarding the TSA1701 DSP. Here's the situation:
I have two 15-inch subwoofers that are functioning correctly. However, when I connect a third amplifier to the system, there's no sound output—only a loud cracking noise (as shown in a video I have). I've checked to see if the DSP (Digital Signal Processor) is the problem, but the same issue occurs with a second TSA1701 DSP unit.
The problem does not seem to be related to the tweeter or the third amplifier. It arises as soon as I plug the jack into LineOut2. If I only have LineOut2 connected with two loads and then add the third load to LineOut1, the same issue occurs.
I've also ruled out the possibility of the DSP's USB power supply being too weak, as I've tried powering it with 10V directly at the socket. All individual components (2 subwoofers, 1 tweeter, 3 amplifiers) work fine on their own, but the DSP starts acting up as soon as both jacks are plugged in.
Additionally, the cracking noise gets louder when I increase the input volume.
I also tried connecting the tweeter to one of the subwoofer amplifiers, and then one subwoofer and the tweeter played perfectly. However, when I added the second subwoofer, the cracking noise returned.
One thing i thought of, is that because the DSP does have 2 3.5mm output jacks, i used 2 3.5 to RCA Cables. Because i only need one output of the second cable i just cut of the other line. Could it be possible that the error is resulting becuase of this? Should i short the wire i cut, or solder a resistor in between?
Is there any other setting or property of the DSP i have to take care of?
Thank you in advance!
My Setup:
TinySine TSA1701
Hypex SMPS400A400
3* IRS2092 500W ClassD Amp
2* the box 15LB075-UW4 15"
1* Master Audio DR8
t.mix 201 USB Play for Audio Input

So i tried a few more things now by disconnecting the speaker from the amp one by one:
(all 3 amps are connected to the dsp at all time):
(all 3 amps are connected to the dsp at all time):
- Connecting one 15" to the amp at ou1 dac0 -> played fine
- Connecting both 15" at ou1 dac0 and dac1 -> cracking noise at both
- i tried muting the outputs in software but the cracking still occured
- Connecting one 15" to ou1 dac0 and the MasterAudio DR8 to ou2 dac2 -> cracking at both
- muted the outputs in sigma studio, still cracking
- Connecting one 15" to ou1 dac0 and the DR8 at ou1 dac1 -> cracking at both
- Then i lowered the volume of the input signal to the minimum, and muted both outputs at sigma studio -> cracking stopped
So i unmuted the outputs and raised the volume and now they are playing fine, even if i raise the volume again
I tried this a view times, it did work most of the times, but not always
- Then i lowered the volume of the input signal to the minimum, and muted both outputs at sigma studio -> cracking stopped
- Then i added the second 15" at out2 dac2 and all speaker started cracking again
