The BDS 235 and 535 owner's manual states that you need an ADAPT to make your system wireless. You do it by connecting the BDS system's analog outputs to the ADAPT's analog AUX input. The ADAPT will then re-stream to your OMNI speakers wirelessly. However, if you listen to the OMNI speakers, and want to listen to the music directly from the BDS system at the same time, there will be a delay in the sound from the OMNI speakers. The BDS speakers will play the music first, and since the ADAPT needs to process the data wirelessly, a delay results. To avoid delay, please mute the BDS system, or connect from the ADAPT line-out to the BDS AUX in instead of the other way around. With this setup, you can only play to the BDS from an OMNI speaker, which will not be delayed in sound.
