Stereo Speaker Protector PCB Layout (Gerber & PDF) Download on Google Drive

Speaker Protector with a delay function that eliminates the thump (jeduk) sound when the amplifier is first turned on and has protection against DC voltage at the amplifier's output so that the speaker remains safe if there is a problem with the amplifier. Especially for the OCL amplifier configuration (output capacitor less) speaker protector is very important to keep the DC voltage from burning the speaker coil directly, if your amplifier is damaged due to a broken or short final transistor.

Well, to prevent this, the installation of a speaker protector will be very necessary as a security measure for the speakers themselves. The component in charge of disconnecting and connecting the speaker line to the power amplifier is automatically part of the relay. This relay will not be able to work without a control circuit. Then this control circuit becomes a sensor as well as a signal in the relay to do various jobs.

The following is the appearance of the speaker protector

At the top there are two 12 VDC sockets for supplying the right and left fans / dual fans.

Simple Capacitance Multiplier Power Supply Filter By Rod Elliott (Gerber & PDF) Download on Google Drive

This is an easy design to build, but requires great care to ensure that ripple currents are not superimposed on the output because of bad grounding or power wiring practices. The schematic is drawn to show how the grounds of the various components should be interconnected, using a 'star' topology. If this is not followed, then excessive hum will be the result. Normally, a schematic diagram is intended to show the electrical connections, rather than the physical circuit layout. This diagram is an exception, and the physical layout should match the schematic (in as much as that is possible, at least). Surprisingly little resistance is needed across a high current connection to produce a measurable performance degradation. Using A Capacitance Multiplier Filter With Class-AB Amps Note that this circuit is quite suitable for Class-AB amplifiers, but since their current requirements vary so widely, adding a much larger capacitance to the output is a must. The dio...

Capacitance Multiplier By Mr Evil / PMI Not Include Snubberized Power Supply (Download Gerber)

This PSU could, theoretically, supply up to 8A for short periods, with the output sagging to ±14V at that current, but it will never be asked to supply anywhere near that much in the intended application and I would rather not push it to the limit in case I break something. It's a capacitance multiplier. These work by amplifying an RC filter, rather than a voltage reference as a normal regulator does. It has certain benefits over a regulator, including lower power dissipation and smoother output ripple (high frequencies are attenuated more than low frequencies). It's improved compared to the usual design that is seen (emitter-follower buffered RC filter) with increased ripple rejection and/or smaller RC filter capacitor due to high input impedance, and lower dropout voltage due to use of pass transistors of opposite polarity to normal (limited only by RDS(on) multiplied by output current for MOSFETs, or VCE(sat) for BJTs). The cost is increased complexity, with six transistors ...
