mono wire into a stereo input
Hello,
if you had to run a mono signal into a stereo input, is the best solution to y-cable the mono source and run identical feeds into the stereo left-right? i'm not sure what happens if you run a mono cable into a trs stereo input. maybe it makes the sound bad or only plays one channel or something. |

Yes, unless what's behind that input has a means of dealing with a mono input. i'm not sure what happens if you run a mono cable into a trs stereo input. You get signal on (usually) the left channel and nothing on the right channel since the ring contact of the jack (usually the right channel input) will be connected to the sleeve of the TS (mono) plug. -- If you e-mail me and it bounces, use your secret decoder ring and reach me he double-m-eleven-double-zero at yahoo -- I'm really Mike Rivers ) |

I have never seen a "stereo input" on a TRS plug. The only time I have ever seen 1/4" TRS plugs used for stereo is with headphones. i'm not sure what happens if you run a mono cable into a trs stereo input. maybe it makes the sound bad or only plays one channel or something. Rather than asking silly questions like this, why not look at some actual connectors? If you plug a TS plug into a TRS jack, you will see that the tip contacts the tip, and the ring and sleeve of the jack are both connected to the sleeve of the plug. (That is, the ring has just become shorted to ground.) On the other hand, if you plug a TRS plug into a TS jack, tip and sleeve contact normally, but the ring on the plug doesn't get connected up to anything and just floats. Knowing this information you can figure out everything you need to know about interconnecting the two no matter what is on them. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Are you sure it IS a stereo input? Not a balanced mono input? What equipment are we talking about? |

The only time I have ever seen 1/4" TRS plugs used for stereo is with headphones. 1/4" TRS plugs aren't often used for stereo input, but 1/8" TRS plugs for stereo input are almost universal on the current crop of pocket sized flash memory recorders. The one exception I can think of off hand is the Korg MR-1, which has one 1/8" TRS jack for balanced inputs on each channel. And just about all built-in computer sound cards that have a line input have it as a stereo configuration on a 1/8" TRS jack. -- If you e-mail me and it bounces, use your secret decoder ring and reach me he double-m-eleven-double-zero at yahoo -- I'm really Mike Rivers ) |

if you had to run a mono signal Balanced? Unbalanced? Connector? Source? into a stereo input, What is a "stereo input"? This doesn't work as a generic question. (Your screen name notwithstanding.) is the best solution to y-cable the mono source and run identical feeds into the stereo left-right? The best solution is developed with knowledge of the actual equipment. We coud discuss several different scenarios and solutions, but guaranteed that all the different solutions are NOT appropriate for all the diffrerent situations. Generically, using a y-cable to feed a mono source into two inputs will work much of the time. But there are many exceptions. i'm not sure what happens if you run a mono cable Balanced? Unbalanced? Connector? Source? into a trs stereo input. Give an example of a piece of equipment you use with a TRS stereo input? maybe it makes the sound bad or only plays one channel or something. I've seen cases where feeding a TRS stereo source into a TRS balanced (differential) mono input will take the *difference* between L and R and render a pretty lousy signal out of it. |

Need I remind people that T, R, and S stand for the Tip, Ring, and Sleeve components of a three conductor plug. 1/4" is a dimension. They don't always go together. TinyTel are always TRS, but are smaller than 1/4", and, like 1/4" TRS connectors are more commonly used for a balanced mono connection than for a stereo (and necessarily unbalanced) connection. -- If you e-mail me and it bounces, use your secret decoder ring and reach me he double-m-eleven-double-zero at yahoo -- I'm really Mike Rivers ) |

Or have you never seen a consumer grade portable recorder newer than about 1970? If he has actual equipment in mind, then let him reveal it. Else you-all are just shooting in the dark. Not worth the keystrokes, if you ask me. The best solution is developed with knowledge of the actual equipment. Of course, but then you'd have to look it up. Suppose he said "The line input of a Zoom H2?" THEN we would have something to work with. |
