Circuit Description 1000W Power Amplifier: Power amplifier has up to 1000 Watt power, this circuit made one channel only so if you want to create a stereo in it must be made one again, actually this is more suitable power amplifier in use for Sound System or outdoor, so if only in use for the house I think is less suitable. Maybe you've seen or even have an active speaker and there is written 1500 watts PMPO (Peak Music Power Output), make no mistake this is different from Power Amplifier Active Speaker, I often dismantle such Active Speaker in it only a power with power no more than 150 watts by using the transformer 2-3 Ampere. PMPO is not a real power which is issued by the Power Amplifier, but counting all the speakers that there is, for example: if there are 5 pieces of speakers on each channel and each speaker has a power of 10 W then it is 100 W PMPO.

Circuit to solve new to the buffer input for the signal R + L and cutting area of ​​the Muting issue and the cut-off point often fear for VR 4 floor hard so I divided into 2 layers using 2 the time that the cut frequency, if wanted. It has layers of fine cut to the same location. I use ic tl072. And replace series capacitor 0.022 with 0.047 . That a soft voice that sounds good offline but not feeling heavy and dial around the back lot, try changing the capacitor. Beyond the traditional. Intended to adjust to extremely low frequency adjustment for the store before so I think that the device is used. Could differ. I sent in this condition before.

It may seem a little excessive, but since I had the programmer, the C compiler and some spare PIC16F627 chips, this solution to handling power on mute, 12V trigger powering and LED for status would be small, reliable and cheap. Three relays would be involved. Mains switching relay, to switch in the 225VA toriodal transformer Output switching relay, to disconnect the speaker from the amp Input switching relay, to remove any input so the output switching relay switches a very small current, prolonging its life (thanks to Mark Hennessy for this idea). Two LEDs would be on the front of the box. One LED for standby, one (blue) LED for power on. The would both flash in turn when the power on sequence runs. Finally, there would be two inputs. One small push button for mounting on the front of the case for manual power on/off, and one 12V trigger input, isolated using a standard opto-isolator in order to prevent earth loops. Thats all there is to it. Without the PCB mount transformer, the PCB...

The output power: 40 w 8 ohm and 60 w 4 ohm load. Preamplifier is used in the same 60 v rails as the power amplifier gain blocks can implement two transistors can provide about 20 v RMS output. This provides a very high input overload. List at least the recommended value is C8. 3300μf capacitor or two 2200μf capacitors connected in parallel would be a better choice. Darlington transistor types of alternative has MJ11014 (Q3) and MJ11013 (Q4) or TIP142 (Q3) and TIP147 (Q4). T1 transformer can be also a 24 24 v or 25 25 v type (ie. 48 v or 50 v center tapped). SW1 switch insert low-cut feature when open. In all cases, Darlington transistors are used as the output device is essential that the transistor (Q2) pass in close thermal contact with the sensor output transistors as possible.
