Περιγραφή
In order to solve the problem associated with OEM amplifiers that feature signal interruption, shutting down when a proper speaker “load” is not present as often found in aftermarket integration, the Prima amplifiers feature ASP (Automatic Speaker Presence). Available as an optional plug-in accessory, this circuit provides the ability to simulate the OEM speakers’ presence during the short time frame the head unit performs the check after being turned on.
General:
AP bit Automatic speaker presence adapter
Resistance for OEM radios/amplifiers in combination with AP bit processors
Usually used on the rear channels when the signal level can not be set
