This stereo features digital signal processing (DSP). You can select pre-configured DSP settings for Fusion^® speakers and amplifiers to optimize audio reproduction in their installed locations.

The stereo uses the same DSP setting for the speakers connected to the internal amplifier and for the line out connection. If you connected speakers to the internal amplifier and are using the line out, the DSP setting might cause the speaker output to be more limited than necessary.

All DSP settings are configured using the Fusion Audio remote control app (Fusion Audio Wireless Remote Control App).
