Philips Bosch System Pre-Amplifier (6 Zone)
The heart of a six zone PA system, the system pre-amplifier provides dual channel operation (calls and background music) for six zones. It has two call station inputs, a selectable filter for optimising speech intelligibility, and separate volume control and tone controls for the speech and background music channels. Six levels of priority are available for music, microphone, call stations, trigger inputs and the emergency input.
Six buttons on the front panel are used to route background music to selected zones. The Plena call station provides zone selection for announcements. The unit has an emergency / telephone input with VOX. When an emergency audio signal is detected it automatically overrules all other inputs.
