Terminating the

EF2211/EF2210

The EF2211/EF2210 is self-terminating so its EF Bus does NOT need to be termi-

nated. However, if you are linking the EF2211/EF2210 to EF2280s, terminate the EF

Bus link.

The following is a list of the factory default settings of the EF2211/EF2210. Since the

microphone and other equipment in your application may have different nominal lev-

els, you can start with a F

ACTORY PRESET (Presets 0-15), change it to match your

environment and then save it within the EF2211/EF2210 as a U

SER PRESET (Presets

16-47). Once you’ve saved a U

SER PRESET, set the POWER ON PRESET to that USER

Figure 5. Only the EF2280 needs to be terminated when linked together with

EF2211/EF2210s.
