When in ONLINE mode you are actively controlling the SDEC-3000 or SDEC-4000. The SDEC-4000 can be configured for Full Range (factory default) or Bi-amp mode. The SDEC-4000 is set to full range to ensure that the bi-amp speakers without built in crossovers will not be damaged accidentally.

Use the below diagram to help you navigate the system while using the DACS measurement system to calibrate your room.

6.3.1Speaker Configuration and Instructions

Begin here by selecting the appropriate speaker configuration. If you are using a bi-amp speaker such as in a Synthesis One Array system, this will also enable the second output from the SDEC-4000

NOTE: You only need to the correct speaker configuration the FIRST TIME you connect to an SDEC. The SDEC will keep the last setting in non-volatile memory until changed.
