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-202) 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 card4) Software: Linux ALSA arecord, aplay and alsamixer for recording 32 bit 48000hz PCM WAV files.

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.

I combined this product with an Olympus WS-802 and the combination makes for a very easy to use system. I leave the parts continuously connected to my phone. When I need to remove the recorder for playback (for example in the car), I just remove the Olympus, and leave the coupler connected to the phone. Great system, easy to use. When I make a call, I have lots of time to turn on the Olympus, and then start recording just before I place the call. When I receive a call, it takes me about 3 seconds to turn the Olympus on, and start recording, and then I pick up the phone, as to capture the entire conversation.The voice quality of the setup is pretty good, it captures only the left ear channel from the phone. I'm guessing this is because of the phone, since normally, the handset is place only on one ear so there's no need to carry two signals (left and right).The phone I use is a Polycom 501 IP phone. But it doesn't really matter what phone, as long as the chord to your handset (that connects to the base) has the same kind of connector as most phones have. Whether IP phone or regular phone, the link between the base and the handset is analog I think... it doesn't make sense to put a bunch of sophisticated electronics (digital technology) into the handset, so I think all phones use analog signal from the base to the handset.

I purchased this to record interviews with my Great Aunt about members of her part of our family that have all deceased. She is 92 and is in poor health, so I wanted to be absolutely sure I didn't miss anything that was said. Because of the holidays and an fall that she had which required her to be moved several times, I did not have a chance to use this for a couple months after I purchased it. It stayed in the box, never touched until yesterday, when I tried to use it. It does not work. When I plug it into the handset of the phone, the handset is silenced, and the line is left open. I reported this to the seller, and asked for what they would like to do. I received a perfunctory response that it is beyond the 30 days and they will not support their product for me. Terrible product, terrible support.
