    By replacing the factory audio system (speakers and / or amplifiers), this equalization is harmful. The bit Ten has an automatic procedure to verify equalization and, if present, can eliminate it. Equalization analysis: setting the source. To run this procedure, follow the instructions as listed below: • Disconnect the bit Ten RCA outputs (Front, Rear and Sub) if they are connected to the amplifiers. • Play track 2 of the bit Ten CD. • Set all tone and equalizer controls to zero (0). • Set balance and fader to center (0). • Don’t change or reset the volume of the input sensitivity calibration (see 6.1.3)

The bit Ten will use these names to reconstruct a full range signal coming from an OEM source with a dedicated multi-channel amplifier and assign the corresponding signal to the respective analog output.
  • Page 24 If you do not use passive crossover filters, each speaker corresponds to an output channel. The bit Ten has 5 output channels; not using passive crossover filters allows you to pilot 5 amplified channels. Of course you can select more than 5 speakers, in which case the system will help implement passive crossovers.
  • Page 25 You can set if passive crossovers exist that manage speaker functional groups. Eg.: If the audio system has passive crossovers, the software will ask you to set them, otherwise press NEXT. A 2 or 3-way passive crossover only takes a single channel.
