Pc not recognizing phonic helix 18 universal mixer

Here is a link to your manual, hope it helps.

As long as your mixer has a line output jack ( L & R or MONO ), yes.

Usually it's the electrolytic caps that go in those, they basically "cook" and dry out, a power spike just pushes them over the edge. I've also had this problem with mine & 2 12 volt switchers for my HD and for the satellite had the same fix. I added a fan which helps. Another solution is to go to a second hand store, find 3 power suplies (15v,15v, 5V) and put them in place of the existing one. I am considering that myself as the firewire packed it in again last month and I had to jump over to the other 5v regulator to get it going again, even tho it was only 0.2 v short! Cheers, Sandrine

This mixer has a multi-effects processor onboard, but the key is understanding the audio signal chain. There is a chance that you have your input audio going through an undesired effect, but without knowing your setup (input source, connections, mixer settings), it would be difficult to pinpoint the problem.

Hallo landgenoot ;)

It seems it is a power supply problem; distorted sound, no meters, solo buttons not working, headphones low level and distorted. One of the power supply voltages might be too low or even missing. The Helix series mixers use mainly 4 supply voltages: + 15 V and - 15 V for the analog part (audio), + 5 V for the DSP and logic and +48 V only for the phantom power. If for example the + or - 15 V is too low, clipping of the positive or negative parts of the waveform (dependng on which voltage is too low) will occur. If possible, first measure the voltages coming out of the power supply. You could use a metal part of a jack as ground reference.
For the FireWire board an extra voltage supplied by the switched PSU is used. It is specified as +12,2 V, but I measured 14 V. This voltage is lowered to + 5 V by a resistor on the FW board and a 7805 regulator. (Not very efficient!) But as far as I can see, the FW voltage is not the problem here. I have some service documentation of the Helix series mixers (12, 17 and 24, so if you need more you can conatct me: frankdevries [at] versatel.nl.

The power supply uses three, 3 terminal regulator chips. You should find +/- 15 volts and +5 volts DC from those. There are two fuses, one for each polarity. If one of those is blown, that would cause the problem and one would need to find WHY it blew before replacing it.
You need to find a competent electronics repair person.

It may be your old computer was running XP operating system and your new one Win7... There is a lot of incompatibility with different operating systems. You can try searching for a compatibile driver. If you cannot find one, the best thing might be to back-step to your old compatible OS and driver.

install drivers with device disconected

You don't specify which model Phonic mixer in question.
Is it a powered mixer ? And are you plugging your speakers into the speaker outputs ? If it's not a powered mixer and you're plugging speakers into the Line Outputs, you're not using a power amplifier between the line outputs and your speakers - this won't work.
If it is a powered mixer and you are plugging speakers into the speaker output connectors and still getting little or no sound, check your speaker cables and the speakers themselves by plugging them into known good amps.
