9. How to calibrate the bit Ten IN Level inputs.
This procedure is delicate and requires particular attention. Improper execution can invalidate the final acoustic results.
The bit Ten outputs must be disconnected from the amplifiers.

10. How to select the speakers available in the system.
Speakers can be selected just by clicking on them.
If the left tweeter, left midrange or left woofer are selected, the software
provides the ability to automatically also activate the right tweeter, right
midrange or right woofer. Once started, this choice sets the dedicated
crossover type and frequencies with default settings. 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.
