The CP52S is a versatile commercial preamplifier designed for use in restaurants, bars, health clubs and offices. The CP52S serves one stereo Zone. One gated Paging Input and four stereo Program Inputs are provided. A Port allows expansion of Page, Program or Zone signals. Three levels of priority are supported:
The Paging Input is summed after Zone Level, Zone EQ and Zone Limiter circuits. If the Page Level Tracks Zone Level switch is on, the Page level tracks the Zone Level.
One of four stereo Program Inputs may be selected. Each line level Program Input features an independent Level control. A gated Program Priority Input is provided. When the rear panel Priority switch is ON and signal is detected at the Priority Input, it overrides any non-priority Program selection. The detector features adjustable Detect Threshold and Release Time controls.
