Audison ASP Prima Series AP Bit Automatic Speaker Presence - Premium Car Audio System for Enhanced Sound Quality | Perfect for Car Enthusiasts & Audiophiles

ASP - AP BIT AUTOMATIC SPEAKER PRESENCE ASP is indispensable when installing speakers with some OEM sources requiring, only at the initial turn-on instant, a resistive load impedance at the outputs to detect the speakers’ presence. In case there is no load, the source disables the outputs, usually only for the Rear section. Therefore, if during the calibration process you cannot adjust the input signal level due to lack of signal on some or all of the speaker inputs, while installing the ASP module, when you turn on the speakers a temporary load will be simulated; afterwards that load will automatically get disabled, fixing the issue. Thanks to ASP, there is no need to mount fixed power resistors at the source outputs; the resistors would produce heat and, in addition to that, would make the source heat up unnecessarily.
