VEC TRX-20 3.5MM Direct Connect Telephone Record Device (ADAPTER ONLY)

So far, great sound quality or has a seemingly high signal to noise ratio. Also, very easy to install and versatile. Two misconceptions, this VEC TRX-20 device does include the spiral cord and the 3.5mm or 1/8 mini jack. The device also connects to the headset rather than at the telephone jack. (Far better on the handset, for maintaining audio quality.) My setup, I plug the output or the 3.5 or 1/8 mini-jack of the VEC TRX-20 into a pre-amplifier, then from the pre-amp into the line-in of an Asus Xonar Essence STX PCI/PCIe computer card. (The ASUS STX cards are one of the best sounding or highest signal to noise ratio sound cards on the market.) Trying to connect this device directly to a computer sound card without using a pre-amplifier may require enabling "mic boost" through the computer operating soundcard frontend settings, and greatly degrading the sound quality or signal to noise ratio depending on the quality of sound card used. I would strongly suggest using a (microphone) preamplifier, costing another $50-100 and can be readily bought through most music stores. The better pre-amplifiers tend to use XLR micrphone connectors, include +20dB mic boost for which I find essential, as well as 1/4 inch jacks rather than the small 1/8 jacks. My equipment: 1) This device, VEC TRX-20 2) Studio V3 Tube MP Pre-amplifier (Settings: w/o +48v turned on, and +20dB Gain and Phase Reverse enabled) 3) Asus Xonar Essence STX PCI/PCIe sound card 4) Software: Linux ALSA arecord, aplay and alsamixer for recording 32 bit 48000hz PCM WAV files. (Photo shows only 16 bit rather than 32 bit recording due to an error on my part!)

This recorder adapter intercepts the handset input/output for a mono recording. Very easy to use. The only limitation is the quality of the telephone line and the telephone itself. However, for two years, we did not disconnect the adapter unit. The telephone handset coil cord jerked the unit wires hundreds of times, the wires separated and static crackled. So we bought two more.

This is a piece of equipment that is specifically designed to connect your landline phone to a digital voice recorder. You plug it into the phone and into the digital voice recorder mic jack. This is my second purchase of this model. The first one lasted for years, and I believe it still works fine. I think I was having problems with my digital voice recorder, not the adapter, but I ordered a new one of both just in case. The problem is that with my old digital voice recorder, the Olympus DS-30, I think I remember that it recorded in stereo - or at least in such a way that the sound came out of both sides of my headphones. With the new digital voice recorder, the Olympus WS-822, the recorded conversations only come out of the right side of my headphones. If anybody knows what I am doing wrong, please let me know. Until then I am not completely happy, but the device does do its job.

Was surprised at how small this is (1.5" x 1" x 1") but it does the job. Setting this up is a 20-second job and it's good to go. The 3.5mm jack will plug into a digital recorder or computer with no problem. The cord could use another few inches, in my opinion, but that also helps keep you from running around with the phone when you need it to sit still. Comes with double-sided tape to help keep things in place as well. Ran through a couple tests and it works great, recording dial tone, key presses, and voice. Basically, if you hear it through the receiver, this gets it. As others have noted, you MUST have a corded handset to use this as it connects in between the cord and the handset.

The device seems to work well. I had been using an old Radio Shack device to connect my digital voice recorder to my phone for many years to record interviews for articles, but it eventually stopped working after the cord got caught in the desk drawer. After I missed out on some interviews that didn't get recorded and had to reconstruct them from my notes, I finally searched for a replacement, and I'm glad I bought this one. It seems to do the job well, and so far all the recordings I've tried to make have worked. The sound quality is decent, and perhaps even better than I had with my old Radio Shack connector. It only took about a minute to set up. It doesn't have the record/play switch that the old Radio Shack adapter had, but that's actually a blessing because that means I don't have to worry about it being on the wrong setting.

Yes it will record phone calls if properly connected, although the quality of the recording is not as good as the call itself. The problem is that once I connected it to the phone tone dialing was disabled. So with this little gem in-line I couldn't even dial the number i wanted to reach. I had to use a wireless phone on the same line to dial the number and get through all the "Press 1 if..." prompts. I tried this on both my wired phone with the same result - no tone dialing.

A little muffled and had a static issue if anything moved at all. Otherwise, it did what i needed it to do.

This type of telephone interface is very hard to find any more so I was delighted when mine arrived at my door, and even more delighted when it worked perfectly.

beutiful little unit works well

Only recorded in mono and not stereo

The jack of this product is at least two mm narrower than it should be in order for the phone plug to fit into. Product is thus useless.
