[Necessary settings on the SX-2000 Setting Software]
• To use the external attenuators, set the SX-2100AO's "Attenuator" item to "Used" for the corresponding zones
in the "System settings" menu. (See the separate Setting Software Instructions, "Audio output settings.")
When set so, the number of zone interlocks with the same number of control output.
• These attenuators are bypassed when the system is in emergency broadcast state. To use the emergency
broadcast, set the "Emergency" item of "Common settings" to "Used" in the "Basic settings" menu. (See the
separate Setting Software Instructions, "Basic settings.")
Note
The speaker line with attenuators installed cannot be detected for its open-circuit state with the Speaker Line
Surveillance function.
