SOURCE: when setting up a sound card to my m4 numark 3

"PHONO" is ONLY for an old school turntable that would require a PHONO preamp, so that leaves, uh, LINE.

It's more than a matter of gain as Phono cartridges require special equalization to restore flatness to the sound recorded in a vinyl groove.

The output master cable is not connecting properly in the back of the mixer. the left speaker falls out. When I push the plug a bit in it makes contact again. I don't think it's a bad cable... Is this

Check your cable again. Cables for patch panels are DIFFERENT. The tip on a patch cable is smaller in diameter and has a point on it. A 1/4 inch TRS cable's tip is larger and has a rounded tip. If you're sure of your cables, then replacing the jack in the mixer isn't so bad if you're handy with a soldering iron.

Where can i get manual for radio shack SSM-8030 audio mixer?

Does your audio-mixer have "pan" control on each input channel?
Pan the channel from "100%-left" to "100%-right".
What about the main output from the mixer?
Does it feed into a stereo-mixer?
Can you adjust the gain on either the left or right channel?

I have mixing analogique yamaha MG2FX4 ana i dont see were is LEFT and RIGHT put of this tabla mixing

I assume english is not your first language, but I think I understand you.

Right first thing is, yes it is marked. You connect the MAIN/Master outputs marked L and R to your amplifier. The tape input is marked L & R too. The stereo channels will be mark L and R but the numbered channels are mono and as we all learnt in our first mixer lesson, to make a stereo you plug left into channel one and right into channel two then pan channel 1 hard left and channel 2 hard right.
If you use a mono source such as a microphone and you want it to come out of both speakers, put the pan control in the center.

No sound from front left channel

Hi, here is a procedure to discover the source of the problem. No sound from the left front channel can have several sources other than the left front channel itself.
Let's assume, for just now, that the speaker is good and the cable to it is good.
Here is a testing sequence to follow:
1 If you have a CD player connected to it. Put a CD in and put it into play mode.
2 reverse the connectors from the CD player to the receiver. See if the sound moves to the left speaker and stops on the right speaker. Or if it plays fine.
3 If the sound reverses channels, That cable is bad. Replace it
4 If the sound is still not coming from the left channel. Check the connections and cables to the speaker. MAKE SURE THERE ARE NO STRANDS OF WIRE TOUCHING THE CHASSIS OR SHORTING TO THE OTHER SPEAKER WIRE.
5 If there were. Correct it. Shut down the receiver and then after a few minutes turn it back on.
6 If it still does not work. check to see if a tiny amount of sound is coming from the left speaker.
If so, turn the music up and see if it pops back on . If that is the case there is a failed resister on the circuit board that is arcing when you turn up the volume. That being the case, it is time to drop off the receiver to be repaired in the service center.
Hope this helps,

Numark Mixer

This sounds like someting is out of phase. Can you describe all of the connections you have to the amp and speakers. Double check them as well to be sure that the positives are connected to the same terminals on the amp and speakers. If that is OK, we'll start looking inside the mixer.

Both left and right speakers play audio for right speaker

I think you mean the left channel is out but when you use test tone, the sound comes from left and right channels through the right channel speaker. If this is case, the switching IC is malfuncting. Unit needs service
