2.2 SWITCHING 100V SPEAKER LEVELS
There are two different configurations for switching 100V speaker levels. The first uses a single amp system which is used
for both Background music and PA paging. This setup mutes background music to “ALL” zones when any zone is paged.
(see section 2.2.1)
The second setup involves a two amplifier system where both the background music and the PA paging has its own dedi-
cated amplifier. This setup mutes background music to only those zones which are being paged. (See section 2.2.2)
2.2.1 SINGLE AMPLIFIER 100V LINE SWITCHING
A single amp system uses one amplifier which is used for both the background music and the PA paging. In this configura-
tion when any zone or zones is paged the background music will be muted to all zones. (Note: If muting is desired for only
those zones being paged a two amplifier setup is required (See section 2.2.2)).
NOTE : Before turning the unit on make sure the dip switches are set correctly.
For single amp switching of 100V speaker levels, Dip switch 1 should be set to “ON”
and dip switch 2 should be set to “OFF” (see Dip switch settings Fig 1.6)
Each zone requiring background music must be switched “ON” from the “Zone Background Music Selector” switches on
the front of the A 4585. (refer to section 1.4)
A background music source such as a CD player is connected to the BGM input (RCA connectors) on the rear of the
A 4585.
The amplifier audio connection is from the “PA Out” RCA sockets on the rear of the A 4585. This is a line level signal and
must be connected to a Line/Aux input on the amplifier.
The amplifier 100V output must be connected to the “From PA AMP” terminals on the rear of the A 4585.
The zone 100V speakers are wired to the “+” and “-” terminals only on the rear of the A 4585 as shown in Fig 2.2A.
(Note: the earth connection is not used for 100V switching system. This terminal is used when switching line level signals.)
