PA-15 Broadcast Interface

The PA-15 Broadcast Interface connects with virtually every panel and delivers 15 watts of power. Enough to drive 15-ohm eight horns or speakers.

The PA-15 delivers speak 36V voltage for coupling to FXO a port or a free netlijnpoort (trunk) of the central. Turn the switch and PA-15 connects to an analog telephone port or trunk or link a "page" gate of the plant. If the central or other system does not contact for broadcasters then the voice detection (VOX) in the PA-15 active and ensures a smooth shutdown after silence detection of respectively 2.5 - 5 or 10 seconds.

After broadcasters switch PA-15 automatically after silence detection (vox), CPC detection (polarity reversal), busy tone detection or fixed timer (adjustable). The PA-15 regenerates loud call over the system on a separate telephone line or port, or by means of a contact provided in bubble voltage detection. The PA-15 provides background music When is connected to an external music source (muted during broadcasting).

The PA-15 replaces the CPA-7B and 2x delivers the power and offers new features
