Does this adapter have internal resistors between the signal terminal on the RCA jack to each of the tip and ring terminals on the 1/8" plug, or does it just connect both the tip (left) and ring (right) signals together with the signal terminal on the RCA jack? The reason I ask is I have an MP3 player that has low-impedance output drivers with no built-in resistors in-line with the output jack, so when the left and right outputs are shorted together with an stereo-to-mono adapter, and the music source material has signal that's all to one channel or the other, but not to both, it ends up distorting, due to one output driver being electrically connected to the other, without any sort of isolation. A small resistor on each channel would prevent the two output driver from "fighting" each other when there's a large difference in signal between them. Can someone who has one of these adapters use an ohmmeter to check the resistance between the three signal terminals?
This part was exactly what I was looking for. It combines a 1/8" TRS (stereo) signal into a single (mono) RCA signal. I used this on my Nascar scanner headphone jack to connect to a portable recording device with an RCA cable.
Monoprice also had a quick delivery and reasonable shipping charges. $2 regular USPS mail for $2 in connectors is a reasonable shipping charge (not like other places who ding you with a $6 UPS delivery for a 1 oz package).
PROS: Quick delivery at a very reasonable cost. Finally, a mail order place that uses USPS regular mail. $2 shipping for $2 worth of connectors is a reasonable shipping charge.
This little piece of marvel makes it perfect for hooking up an mp3 player or music reproduction device to any speaker system. The plastic grip is the weakest part due to its durability. It may last 20 years, or it may last 1 year, depending on the heat it takes from the equipment it is hooked on to.
PROS: Super economic, gold plated, tight fit for excellent connection
CONS: The black plastic grip could be a little better in terms of durability
