• "Name" is fixed, and cannot be edited.
Note
Shown above is the setting range when the volume is set to the default value (0 dB). This BGM offset
range varies with the set volume value. For example, when the volume is set to "–10 dB," the BGM offset
range becomes from 0 to –60 dB.
• SP line voltage (SX-2100AO only)
Select the speaker line voltage.
100 V (default), 70 V, 50 V Available Settings
Note
The speaker line voltage selected here must be matched with that of the VP-2000 series or VP-3000
series Amplifier.
If not matched, change the amplifier's speaker line voltage referring to the separate Installation Manual.
When an emergency broadcast is set to "Used," the control output of the channel that is the same as
the number of zone for which "Attenuator" is set to "Used" is activated in emergency broadcast state.
Use this control output to bypass the external attenuators in the emergency state. See the separate
Installation Manual, "Connecting the SX-2100AO to external attenuators."
When "Attenuator" or "EOL" is set to "Used," the unit configuration is displayed on the screen as
shown below.
Appears when "EOL" is set to

Note: To set the VP-3000 series amplifiers, select VP-2122 for VP-3154, VP-2241 for VP-3304, and VP-
2421 for VP-3504 since these models do not appear on the pull-down menu.
