2 way Active Crossover
Therefore this architecture represents the simplest access I could booty and still get the adapted outcome.The band akin audio arresting enters the absorber area it is astern out of phase.This is to atone for the filters which will alter the appearance afresh appropriately abiding the arresting to it’s able phase. The filters are more-or-less accepted low and aerial canyon filters appropriately however, added capacitors and resistors accept been added in adjustment to get the altruism bottomward to a minimum appliance alone E12 components.
This alive Cantankerous over is adequately beeline forward. It consists of a absorber and two 3rd order, 18 dB per octave filters. One low canyon and the added high. The cantankerous over abundance is set at 2Khz and is advised for AEK’s 400watt per access PA/Keyboard Amp systems. Obviously alone one access is apparent here.
This ambit may not be of awfully abundant use to anyone as it was accurately advised to clothing the applications. It is not capricious or switchable for two reasons. Firstly, it didn’t charge to be back the backdrop of the apostle arrangement were already known. And secondly, the added complication was put into the accurateness of the crossover rather than it’s flexibility. The filters are akin in account to anniversary added as able-bodied as can be accepted appliance alone E12 components. If switching were to be active to accord a ambit of abundance options, a accommodation would accept to be fabricated on clarify accuracy.
The alone added way to accomplish a accepted crossover architecture and advance accurateness would apparently be to use Switched capacitor clarify architecture blocks. In theory, two 18or 24dB per octave filters could be complete such that they tracked anniversary added by actuality bound to the aforementioned clock. This would be a nice agreement but I haven’t had the befalling to prove this technology for this affectionate of application. My primary affair was the breach through of switching babble appliance such a design.

2 X 0 32W BA5386 amplifier schematic
Amplifier circuit above scheme is a combination of the two IC was then made into one of its supply voltage so it does not require a lot of supply voltage and output a stereo input. Output issued also very low at 2 X 0.32 W and has 8 ohm impedance. Indeed, this amplifier has a very low output, but the amplifier is quite easy to make and does not require much cost. The voltage required at least 4 volts while the maximum supply voltage of 12 volts.

Latch Switch 2
This circuit uses a Silcon Controlled Rectifier (SCR) as a latch switch. Once enabled it can only be turned off by pressing S2 or power is removed from the circuit.
Latch Switch 2 Circuit Diagram
Circuit Notes:
The load is represented by the 1k resistor and orange LED, although the C106D can handle much larger loads. Once the On switch is pressed, the SCR receives a voltage on its gate terminal and goes into forward conduction and conducts current through its anode and cathode terminals. This current remains to flow even when the on switch is released, so the LED remains lit.
The load can only be turned off by pressing the Reset switch which is a Push-to-Break non-latching push switch. Note that reset switch must be able to handle the full load currents and voltage.

2 Channel MOSFET Car Audio Amplifier
This Car Audio Amplifier to run an older 8 inch pioneer sub in a bandpass box . This delivers as expected. Subwoofer sounds perfect. I tried to run it off the stock deck using the high pass but it wouldnt turn on. I took a jumper wire and touched the remote to the positive and it fired up immediately. Dont expect any help from Boss via their phone number on the box. I waited for 20 minutes before I just decided to hang up and just pick up a new deck. It sounds great.That this amp would not do a good job pushing a subwoofer is that it only has a "Subwoofer level control". This is not to be mistaken for a crossover/low pass filter. You need some form of crossover to keep it from sending high frequencies to the speaker.
Technical Detail for Boss Audio R1002 2-Channel Mosfet Power Amplifier with Remote Subwoofer Level Control :
- 2-Channel MOSFET Power Amplifier
- Remote Subwoofer Level Control Included
- 100W x 2 Max Power
- 100W x 2 RMS Power
- 50W x 2 Max Bridged Power
