How many volt? for power supply phonic mixer MM 1202

You would connect the xlr left and right outputs to a power amplifier and then the speakers to the power amp. The mixer will not drive a set of speakers by itself.

Looks like both units accept 1/4" jack & I think the 1202 is unbalance out, so just use a standard screened mono (i.e. 2 pole "TS") jack to jack lead & you should be fine. Good Luck! :-)

I tells the power supply model numbers on the back of the unit above the power connector plug. It doesn't tell the specs as of how many amps but does describe several voltages of AC it would work on and also gives several model numbers of the correct power units that are sufficient. If you don't use one the recommended units, it could malfunction and give extra static noises caused by improper filtering of the power. It shows on page 8 of this manual:

I hope this helps you.

The E-8 mixer lights the power LED from the +15 volt regulated power...

The TYPICAL power supply might be similar to that on page 2 of:

Here is the E-8 schematics but missing the power supply... you know the drill... same as above:

Since your unit has "morning sickness" I think you will find a BAD siolder joint in the power supply... The supply is very simple and it takes a trained eye sometimes to see the little gray line in the meniscus of the soldering at a lead that indicates a bad connection. Tracing the +/- 15 vp;ts should be an easy task. Pay particular attention to heavy components and the leads of the three terminal regulator chips... I would look at the +15 volt one closely...

You would need TWO DC supplies as they use AC so they can create both a plus and minus 15 volt power source to run the internal op amps.

Here is a schematic for the 1202 which has same power supply configuration as the 802.

Scroll down to the little link "Get Manual" and download the service manual and schematic. You will find the power input in the upper left corner of page 5.

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.

Groeten, Frank.

I assume you are using CONDENSER microphones, as these are really the only ones that can use Phantom power. Also do NOT use any MONAURAL connections to MIC jacks while using Phantom power.

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.

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.
