    Always disconnect the power supply cable and any audio cables connected to the subwoofer before moving it. This will prevent a short circuit or damage to any plugs or connecting cables. Before switching the unit on Double check that all connections are correct and that the volume is turned all the way down. iDSP manual rev1 simon.indd 2 12/7/20 8:28 AM...

  • Page 5: Device Connection And Setup

    Connecting the iDSP to a typical AV receiver is easy. Simply use the provided RCA cable by plugging the RCA end into the ‘sub out’ port on your AV Receiver (AVR) and the other end into the input side of your iDSP. It is okay only to use either the red or white RCA plug, and leave the other one unused, but you can also use an RCA Y Adapter that is 2 Female to 1 Male to eliminate this.
  • Page 6 If you have two subwoofers in your system, you can use an RCA male to dual RCA female cable (also known as an ‘aux splitter’) or other types of “Y” cables on the output of the iDSP to hook up both of your subwoofers. You could even use a typical RCA male to stereo RCA cable, and use the white RCA plug for one subwoofer, and the red RCA plug for the other subwoofer.
  • Page 7 OFF, as the iDSP does not have any hardware controllers and leaving these on can result in a distortion of frequency response (because nothing is connected to these pins in the iDSP. Note: If you restore the iDSP to factory defaults, you MUST turn these settings off again as they might be activated by the factory reset.
  • Page 8 If the sweep is not audible once confirming the subwoofer is connected correctly, try restarting the app and or removing and then reconnecting power to the iDSP hardware unit. The iDSP unit has a standby function and will temporarily shut off if it does not receive input for a period of time, but you can quickly kick it out of standby with a power cycle.

  • Page 14 (for example, an area of a few square feet, like an armchair or at most an entire couch). Although the algorithm isn’t optimized for it, and OSD Audio does not recommend it, you can try to use it to correct the sound across the entire room by averaging responses across the room in the 2nd step.
