I have my BCD3000 connected to a new installed PC just for DJ-ing. Have not used/installed the BCD3000 before.
Downloaded the latest driver, installed the driver, connected the BCD3000 when the installation asked for it.
I left all the settings as default and connected the BCD3000 to my AMP using the Master Output.
Installed Traktor 2 v2.6.0, ran through the wizard, made sure the BCD3000 (ASIO) is the audio driver. I made sure the BCD3000 controller was recognized. All this using the info one can find on the internet.
So, when I start a record, no sound from my AMP.. But I do hear the music when using my headphone.
