Hi folks. I built this for a DJ friend of mine and he loves it. One issue is the RCA jacks produce some what of an Echo. He calls he calls a warble sound. The small phono-out does not do this, clear. This is what it sounds like clear:

For those of you who don't know, the PHONE has a DC Bias, and it is recommended that you decouple it as shown by these links:

"Par 3 - Line-out Connection It’s not recommended to use GBUF as audio ground when connecting to other electrical equipment such as power amplifiers or PC line-inputs. The GBUF pin is internally biased to 1.25V and it is possible that a ground loop is formed when the GBUF is connected to the ground of the target device. This may damage the
VS10XX device and will prevent normal operation."

Here is the project. You can see I put in the 100 ohm resistor in series, with 10uf cap, and a 10K resistor to ground for each channel.
