An elegant desktop four zone paging mic with pre-announcement chime and balanced line level output. It allows the operator to manually select any zone or any combination of zones. Also includes an all call & cancel button. Connections for remote power (24V dc) and the balanced audio output are via an 8 pin RJ45 socket which is connected to any of the compatible Redback audio products listed below. Output volume is adjustable and the unit has an inbuilt pre-announcement chime. The high level balanced output allows transmission over 300m without interference. Suits for line level or 100V line zone switching. Operates as a stand alone paging solution or in conjunction with the compatible Redback products listed below. Requires 24V DC plugpack.

Compatible Redback Products:
A 4469/89/89A Four Zone Relay Audio Switcher Unit.
A 4580 Paging System Controller.
A 4270 Public Address (PA) Mixer Amplifier 125W 100V 4 Zone.
A 4280 Public Address (PA) Mixer Amplifier 250W 100V 4 Zone.

Use with Four Zone Relay Audio Switcher Units
There are multiple configurations for pairing the A 4488 with the A 4469/89A four zone audio switcher units. Two examples are detailed below. The first details connection between A 4488 and multiple individual zone amplifiers via either line or mic level (mic level shown in diagram)

The second configuration allows for a single zone amplifier powering all zones at once. In this configuration the amplifier output is fed into the A 4469/89A and speaker circuits are connected directly to the zone outputs. The A 4488 can then be used to page each zone as desired.

A maximum of two paging consoles can be connected to the audio switchers at the same time. These work in a “first in, best dressed” arrangement. Each unit must be assigned an ID number through DIP switch settings on the rear of the unit. Connection between the A 4488 and audio switcher is via a Cat5e cable which carries power and the balanced audio output from the microphone.
