This amplifier has been tested to make sure all components work.
The APEC on this particular amplifier has been disabled. The APEC limits power therefore by disabling it, the amplifier can utilize its full power.
The ADP series employ fully regulated power supplies which deliver constant output voltage independent of the vehicle’s battery voltage. Should the vehicle’s battery voltage drop below about 11.5 volts, the amplifiers will simply loosen up their regulated status and only continuous output power would reduce slightly. The output power with music shall remain essentially the same.
ADP amplifiers employ 24dB/octave Linkwitz-Riley crossovers for both High and Low pass types and ultra low noise integrated circuits are used throughout the front end stages.
All AD DESIGNS amplifiers have the following features unless noted:
* Balanced or unbalanced inputs, switchable by either PCB DIP switch or front panel switch depending on model type.
* Auto turn on via DC voltage sense on inputs when in BALANCED mode only. Damage will de done to head units with BTL outputs if connected to an UNBALANCED input.
* If the hard wired remote turn on feature is used, the auto turn is automatically disabled.
* All the amplifiers feature APEC circuitry which prevents clipping and distortion. The current consumption (and heat) are vastly reduced when APEC is activated.
* Each amplifier (except ADMP 900.6) feature peak power LEDs on both front panel and the remote. The remote’s LED turns from GREEN to RED to when peak power is reached.
* The amplifiers are protected against over voltage of the battery supply (16.3v shut down), reverse polarity of the battery connections, thermal shut down should the heat sink temperature reach 75 deg C (167 def F), DC protect should and DC in excess of about plus or minus 5 volts appear on any speaker output and short circuit protection on the speaker outputs. (AD does not recommend deliberately shorting the speaker leads or shorting speaker leads from one channel to the other.
* The class D amplifiers on every model use ultra low gate charge MOSFETs which are critical for the operation of these full range class D amplifiers. Even the mono blocks use the same full range designs!
* ADP 700.1/1200.1 may be bridged with a 4 ohm load to deliver 1400w and 2400w
respectively OR may be cascaded with each subsequent amplifier driving it’s
own woofer where the master’s controls affect all further cascaded amplifiers.
