![]() ![]() Seems to me that if someone wanted to use either jack on this machine back when it was new (appears to be year 2000 according to the manual) they would want their mono sound coming out of both channels out of the headphone jack, but they would especially want left and right channels combined for recording purposes using the aux. Any recording on the ctr-117 using this particular aux with no adapter just pretends the right channel isn't there at all, it does not combine channels into mono, the left/right stereo test only plays the "left" sound when played back on the machine. Seems like it's just a way to advertise it as having an aux, while technically true it's the bare minimum. The headphone jack is one thing but the aux being this way is what is most strange to me. This is far more important than buying exotic cables. But to be sure of getting good results, you must consider the details. You can often ignore the details and get good results. To figure out how things are wired, input and output impedances, and other details that are sometimes very important you must RTFM (Read The Manual)! Your Mileage WILL vary!! When wiring audio equipment, there are a lot of variables in "standards" and practices. Here the tip is the output and the ring is the input. The exception is for the Insert Input/Output jacks. If the signal is unbalanced the ring may be open or connected to ground. generally, for balanced signals, these are wired: Phone plugs are often used for line level inputs and outputs on mixers designed for small bands and the cheaper professional mixers. The may be some equipment where Ring 2 is the Microphone and Sleeve the common. These plugs are often found on cell phones and recent laptop computers. ![]() The ring nearest the tip is called ring 1, the one nearest the sleeve is called ring 2. Some recent 3.5 mm phone plugs, have a second ring. ![]() Using phone plugs for general inputs and outputs for equipment appears to have started with sound cards for computers and become common with flat screen TVs. Most mono plugs and jacks are wired the old way but a few may have the tip and ring wired together. Thes plugs are called three conductor or stereo. Stereo headphones are generally wired tip - left channel, ring - right channel, sleeve - common (or ground). ![]() To accommodate stereo, a third conductor was added in between the tip and sleeve. These plugs are often referred to as two conductor or mono The 1/8 inch (3.5 mm) phone plug appeared later. The shaft of common phone plugs was 1/4 inch in diameter. They just had a tip for the signal and the sleeve for the common (or ground). Phone plugs were in use for headphones a hundred years ago. It's a mint little recorder, seems almost brand new, like new old stock, still in the box too. Thanks for the responses and suggestions. Looks like a Y adapter will be the best long term solution if I wanted to use it to record from the computer then, settings if I am just messing around. I've seen a headphone jack do this on a cheap little radio before though. Looks like my biggest confusion was the aux completely ignoring the right channel by shorting to ground which I did not think would happen. In response to VWestlife (like your videos btw), I recorded my stereo test cassette using a stereo deck and played it on the ctr-117, now it's combining both left and right channels into one, but using the headphone jack it's only on the left side, that's fine and I suspect it's normal, only one internal speaker anyway which is what it was mostly meant for. So it is recording mono onto both channels then. This particular test was about -20 on the left channel and -22 on the right. Difference in the levels between left and right is pretty negligible for it's intended purpose. Success at both of them, the stereo deck plays the recordings Side A and side B individually using both channels, so all four tracks are in use. I just made a voice recording on side A and side B on the ctr-117 using the internal mic and played both sides on a stereo deck. ![]()
