Overview
2.0 SETUP
2.1 Setup Guide
The A 4585 is a 16 zone paging system which switches 100V speaker levels or balanced low level (line levels) signals.
Background music which can be piped to any zone is muted when paging is initiated by the A 4586 paging consoles or
when the Evac input is triggered.
WARNING : For correct operation the dip switches 1 & 2 need to be set before using the unit.
If the A 4585 is being used in single amplifier mode (see section 2.2.1) dip switch 1 must be set to “ON”
otherwise if the unit is being used in two amplifer mode (see section 2.2.2) then dip switch 1 must be set to “OFF”
When using the unit for 100V speaker switching Dip switch 2 must be set to “OFF”.
If line level switching is required then Dip Switch 2 must be set to “ON”.
Failure to set the dip switches correctly might result in the unit malfunctioning.
