Dual Amplification 'B; Additional External Amplifier Connection - RCF Invision 354MP Manuel De L'utilisateur

DUAL AMPLIFICATION 'B'

In this mode, ES 3323 is linked to an additional external amplifier (i.e. RCF UP 2321) for music only
(while the internal one is for paging only).
ES 3323: PAGING
See the manual section 'Additional external amplifier connection', paragraph 'B'.
IF NO PRIORITY EVENT IS IN PROGRESS:
•
The music (internal or external player, ES 3323 sends the signal to the external amplifier) is
present in all the zones having the respective MUSIC button
and PAGING [10] buttons turned on).
•
The mix of all the channels 1 ÷ 4 (through the ES 3323 internal amplifier) is sent to all the zones
having (only) the PAGING button
When a priority event is in progress (i.e. an announcement), the signal having the priority is sent
to the 3 zones by following the rules listed in the previous manual section 'Single mode operation',
including the OVERRIDE mode.
The music is held (if activated) in the zone(s) not affected by the event with priority.
}
The attenuators control the paging levels only (if the OVERRIDE function is not activated).
