Question - how to hook up telephone through stereo?
Hello
I have a question that I'm desperately searching an answer for. I am wondering if it is possible (I'm pretty sure it is) to hook up the telephone through my stereo (or even the computer). I have a group meeting to host at my place, and would like to have a friend who will be calling in via phone participate. But I want to avoid having to use speakerphone, since speakerphone is always crappy sounding/distorted, etc. I know in the past i messed around a bit with wires and what not, and was able to run my phone through my little tabletop tape/cd stereo. The sound was awesome. I'd like to do this again, and would like some on advice on what i might need to buy to make it happen. Or if its possible to hook the phone up through the computer, so the audio runs through my computer speakers (and I guess then I could hook up some mics to send the audio out).... would that work? Any advice on the best/easiest way I can do this to achieve the best possible sound is much appreciated. Thanks!! Dave Allston |

The device used is called a Telephone Hybrid Coupler. It provides for a line level input from a mic mixer, a line level output that can be added to a program mix and/or sent to a speaker, and a hookup across a phone line. A phone is use to establist the connection and then a button is pushed causing the coupler to "seize" the phone call. Telos Systems makes some of the best couplers.

JK's sound better and have less null problems IMO. Here's one even cheaper than the cheapest JK by a company I can recommend. I haven't used this particular device but I've bought maybe a dozen of this company's other devices and been on the phone with the owner/designer several times: http://www.broadcasttools.com/view_product.php?pid=113 Of course, the results will be less than perfect but for $119 instead of $700 and up, what do you expect? If that's still too much money you can always use a coupler (NOT hybrid), but there is no feedback prevention in a coupler. Still could work if money is your main limitation: For $88: http://www.bswusa.com/proditem.asp?item=HC-1 Julian |

Still could work if money is your main limitation: to the op... is your friend on the phone going to only be talking, or only listening or will (s)he do both??? the problem with both is that simple bi-directional connections to the phone create a feedback path, thats what the hybrid takes care of.... if you need a bi-directional set-up your best bet is to get a decent speaker phone...they have a hybrid and automatic talk/listen switching going on...it's not a simple connection and an amplifer... Polycomms are very good, but not cheap... Mark |

It has an automatic camera control which follows whoever has their mic turned on and 3 of the largest damn plasma screens I've ever seen. It's awesome to see it working. Julian |

I have a question that I'm desperately searching an answer for. I am wondering if it is possible (I'm pretty sure it is) to hook up the telephone through my stereo (or even the computer). Sure there are several ways of doing it. Which one is likely best for your situation depends on several things you did not disclose (budget? one-time vs. ongoing, one-way or two-way, etc. etc .etc.) I have a group meeting to host at my place, and would like to have a friend who will be calling in via phone participate. But I want to avoid having to use speakerphone, since speakerphone is always crappy sounding/distorted, etc. What does "participate" mean? Will they be delivering a speech to the people assembled at your place, or do you expect a two-way conversation? If it is one way only (from the phone line to your stereo) then you could likely use one of the inexpensive gadgets from Radio Shack which are sold to people who want to record their phone conversations. OTOH, if "partcipate" means 2-way, then you have no real choice but to use at least a speakerphone, if not a real phone patch or "hybrid". Not at all clear whether the "crappy sounding/distorted" signal is caused by the speakerphone, or by the telephone at the other end and/or the telephone system itself. Remember that the telephone system is *by-definition* quite low "fidelity". I know in the past i messed around a bit with wires and what not, and was able to run my phone through my little tabletop tape/cd stereo. The sound was awesome. I'd like to do this again, and would like some on advice on what i might need to buy to make it happen. Or if its possible to hook the phone up through the computer, so the audio runs through my computer speakers (and I guess then I could hook up some mics to send the audio out).... would that work? There is significantly more to a speakerphone (or a phone patch/hybrid) than a speaker and microphone(s). There is actually a rather sophisticated circuit which prevents feedback at your end from the sound of your microphones coming back out the speakers at your end. Any advice on the best/easiest way I can do this to achieve the best possible sound is much appreciated. Thanks!! What is your budget? How often are you going to do this? Do you need one-way ("simplex") or two-way ("duplex")? |
