May 5, Video production Seven hard-won lessons in virtual event production. If you try to send a balanced signal from a mixer to the stereo input of something like a PC, both the left and right will sound the same but one of them will have a reversed polarity, creating a bizarrely hollow sound that seems to come from everywhere but the speakers.
Basically, it comes down to the fact that the circuit for a balanced connection is more expensive than that of an unbalanced connection. This can sometimes be the point at which some manufacturers will cut corners. Also, the line-signals sent by instruments or devices like keyboards are much louder than those sent by a microphone so the signal-to-noise ratio is not in much danger of becoming imbalanced, so sometimes, a balanced connection is simply not necessary. As such, it must seem pretty strange that, more often than not, passive, weak-signalled instruments like electric guitars and basses still use an unbalanced connection.
People have tried to experiment with balanced guitars in the past but quickly discovered that, due to the high impedance of the instrument, a balanced circuit caused too much of a negative influence over the interaction between the guitar and amplifier.
Doing this means, that a distance of tens of metres can be bridged without any unwanted noise or hum. To use a D. Most of the time, a D. I have a diatonic accordeon, it sends two signals: bass and melodies.
It has only one stereo jack output, so the left can be used for basses and right for melodies. Problem was: these cables tend to break and more important: sound people always mess up the balance between bass and melodies, i want to be in control myself. It gives only one signal and it combines the basses ans melodies on one cable. Soundwise its ok, because the signals dont bleed to eachother there are no phasing problems because of the reversed polarity.
But: it is unbalanced also because of this. If i put it into a di, one of the channels bass or melodies isnt coming trough. Why is this? And do you know a solution in which i can use one mono signal but make it balanced? This is why one of your signal is lost. You can do this by plugging them into a small personal mixer like the Behringer Xenyx and leave the pan knobs centered. A more simple and elegant but also more expensive solution is to use the Radial JDI instead of the Behringer mixer.
Press the merge button and the link output will turn into a second unbalanced input. Both unbalanced inputs will be merged and will show up at the output as a single balanced singnal.
Is that a typo, did it mean to say balanced? I can barely hear anything. AM I using the right cable? The balanced or unbalanced stuff confuses me?
If you use another cable like TS one black ring or TRRS three black rings then that might be why the sound is louder if you partially pull the plug out. Would this solve the issue. I supposed the output of the Sax headphone port is balanced so Im not sure what I need to use hear. Any help would be appreciated. If you use the output for a regular headphone, is the sound level okay?
What input do you use on the mixer? If you use an instrument input, like a Hi-Z input, then the volume would be very low because of the high impedance of the input.
A regular line level input should also suffice without impacting the volume to much. Discard them, even if the problem seems to be in just one or two spots.
Whether or not to reuse their XLR connectors depends on how much wear and tear they have accumulated. Cables tend to fail at the flex point where they enter the connector much sooner than elsewhere.
Actually soldering the cables to the plugs is a skill beyond the scope of this article, but Local offers an excellent training class. One thing to keep in mind is that shrink-tubing does NOT make good strain reliefs, because when shrunk it is too stiff and simply transfers the stress point to the far end of the shrink-tubing.
Use plain PVC tubing available in many sizes from electronic supply stores instead. It is much more flexible and will form a smooth curve to more evenly distribute the stress. I save the sections of the outer plastic jacket I strip off various cables while attaching plugs, and use them for strain reliefs on smaller diameter cables. Some brands of microphone connectors offer a means of connecting to the metal shell and some do not.
There is still a considerable controversy over whether to ground the connector shell sometimes called body or not, and if grounded, whether to ground the shell at only one end of the cable. There is no simple, always-correct answer. Here are the possibilities using 2-conductor cable with the balanced audio always connected to Pins 2 and 3 at both ends :.
Shield connected to male and female Pin 1; male connector shell connected to Pin 1; female shell floating. Shield connected to male and female Pin 1; female connector shell connected to Pin 1; male shell floating. Shield connected to male and female Pin 1: both male and female connector shells connected to Pin 1.
Third wire connected to male and female Pin 1; shield connected to male connector shell; female connector shell floating. Third wire connected to male and female Pin 1; shield connected to female connector shell; male connector shell floating. Third wire connected to male and female Pin 1; shield connected to both male and female connector shells. In the following discussion, I will assume the standard configuration in which a male plug will be connected to an input and a female to an output.
To begin with, if the cable is to be used with phantom-powered mikes, there must be a current path between both Pin 1s, so any further discussion is moot. But if you really, really must break the Pin 1 circuit, connect the shield to Pin 1 at the female input end.
What to do? Consult a Ouija board. Actually, you could do worse. Or you could make up cables in each of these configurations, and try them oneby- one. I have made up several 3-conductor cables wired as per Number 5.
On those occasions when I have encountered problems with the 2-conductor cable, the first thing I try is replacing the T-power microphone e. This usually eliminates the trouble. In about a year or so, the aluminum oxidizes and forms an insulating layer, destroying the integrity of this grounding function and ability of the case to intercept interference.
Loosening and retightening the screw a couple of times restores the effectiveness of the connection. But in only two instances was there any improvement. Most of the situations occurred in proximity to AM radio broadcast towers antennas , and the signal strength was simply so high that nothing could keep it out.
One time it was possible to move the recorder very close to the mike, and connect it with a much shorter cable. Some sound mixers RF bypass the inner conductors with 0. You need a disc ceramic type low internal inductance and to keep the two leads as short and straight as possible. Solder one capacitor-resistor combination between Pin 2 and Pin 1, and another between Pin 3 and Pin 1. Using chip components will make it much easier to install the parts. I have been able to conduct some experiments on stage with buzzes from H.
Crossing these power cables at right angles was of no help. Only separating the two cables with an apple box worked, but there is always the danger of having the mike cable pulled off the box to land back on the H.
It is better to re-route your audio cable to avoid crossing any electric cables if at all possible. Another common problem occurs with outdoor cable runs. Electricity always takes the path of least resistance—literally. However, some of the current will still flow through other paths that have higher resistance. For example, if lighting units are set on the bare ground, there may be a flow of leakage current through the soil between the lamp stands and the grounding point of the generator.
While damp ground can be dealt with by gaffer-taping the connectors, protecting them from actual liquid water requires more extreme measures. The best one is not to do it in the first place: if you know in advance that you will need a long cable run underwater, make up a single continuous length cable. You can always make several shorter ones out of it afterward. If only mud or dirt is the problem, Neutrix makes a line of heavy-duty mike connectors.
The male has a stainlesssteel barrel which resists deforming when stepped on or run over, and the female has an external rubber boot that mates with the open end of the male shell and also covers the latch button. This combination keeps out non-liquid contamination, and if you apply some silicone sealant inside the cable strain relief, will handle liquid splashes as well as long as the sealing lip of the rubber boot is not damaged.
Start a spiral wrap around the cable, about six inches from a connector, pulling the tape until it is fully stretched about three times its original length. Completely overlap the first turn, then be sure to overlap the remaining turns almost half the width be careful to avoid bumps from creating a third layer. Continue wrapping six inches into the next cable. Finish with the last turn completely overlapping the previous one. Squeeze all the tape with your hands to ensure complete adhesion of the layers.
Unfortunately, removing the fused mass afterward is difficult. Slice through it with a sharp blade, gradually going deeper with each pass, and being careful not to nick the cable jacket or connector shells. Skip to primary navigation Skip to main content Skip to primary sidebar Login.
