This Redback 4 Zone 250 Watt 100V Public Address Mixer Amplifier is similar in functionality to the recently released A 4377/A4387 amplifiers with the addition of four 100V line output zones. During normal use, you are able to select via the front panel switches, any zone on or off to control BGM programming.
Remote paging to each zone is made possible by connecting the A 4488 paging console to the amplifier via Cat6 cable (2 consoles @ max 300m). This allows for paging to selected zones or all call, muting BGM to all zones. At the completion of the announcement, music will be restored to previously selected zones. BGM can also be selected on or off to all zones remotely from the A 4488 paging console.
When using the paging console, these microphones assume priority between input 1 and input 2 on the amplifier. If two consoles are connected, they operate on a first in, first served basis, activating a system busy indicator on the inoperative console.
