AMP IN 1 (ZM 2100 only, removable connector)
Input for the connection of the first external amplifier 100 V output in the ‘power sharing’
configuration (all zones are only served by either one or two amplifiers, one for paging
and one for background music).
If ZM 2100 is set to the single amplifier mode (through its respective dip-switch
28
), the
external amplifier is used for both paging and background music.
If ZM 2100 is set to the dual amplifier mode, the first external amplifier is used for
background music only.

directly to AMP IN 1
63
(see the next ‘ZM 2100 - 0 dB zone commutation’ manual section). In this case, all
external amplifier inputs will be connected to the loudspeaker outputs

(here used as
six 0 dB audio outputs, one per zone).

AMP IN 2 (ZM 2100 only, removable connector)
Input for the connection of the second external amplifier 100 V output in the ‘power
sharing’ configuration – dual amplifier mode (all zones are only served by two amplifiers,
one for paging and one for background music).
The second external amplifier is used for paging only.
