Make sure to factor for amplifier output power when you're ready to purchase your next stereo amplifier or receiver. Power is measured in watts per channel, and the decision about how much power you'll need should be based on criteria including:.

Match the power requirements of speakers with the output power of the amplifier or receiver. Power should equal the impedance rating for each of the speakers.

Power output and speaker volume follow a logarithmic, not linear, relationship. In such a situation, the actual difference in maximum loudness would be just slightly louder; the change is only 3 dB. It takes an increase of 10 dB in order to make speakers play twice as loud as before a 1 dB increase would barely be discernible. Some speakers must work a little harder than others to achieve a specific volume output.

Certain speaker designs are more effective than others in projecting sound evenly across open spaces. If your listening room is small or carries audio well, you may not necessarily need a super-powerful amplifier, especially with speakers that are more sensitive to power.

But bigger rooms or greater listening distances or less sensitive speakers will certainly demand a lot more power from the source. The most common measure of power is root mean squarebut manufacturers can also provide values for peak power.

The former indicates continuous power output over periods of time while the latter indicates output in short bursts.

Speaker specifications can also list nominal powerwhich is what the speaker can handle over periods of time. Overpowering a speaker by supplying more watts than it needs can lead to damage to your equipment.

Some manufacturers inflate specifications by measuring power at a single frequency, say 1 kHz, rather than an entire frequency range, such as 20 Hz to 20 kHz.

For the most part, you can't go wrong with having more power at your disposal than not, even if you don't plan on blasting music at concert-like levels in your listening spaces. Amplifiers with higher power ratings can deliver without needing to be pushed to maximum output limits, which keeps distortion down and audio quality up.

Suman Karmakar Certified Buyer 1 month ago. Back to top.This is linear power amplifier Watt which need advance knowledge in electronics since the schematic diagram is very complex for hand made circuit. I think you have to re-design the schematic diagram using circuit diagram software designer such as diptrace, eagle, expresspcb ect.

This kind of power amplifier circuit need high power consumption, so you need to build the power supply carefully. O Audio Power Amplifier so plz.

If ur having some then plz. I looked over a little something similar to your post at techcrunch… anyhow, I think car audio is normally misunderstood but has some good quality manufacturers also. The schematic is very helpful, but please just put the watt rates of the resistors, or else a part list with the watt rates next to each resistor, with the schematic aswell, and R30 has no ohm value.

We have tested all these circuits in our lab and we found all of them performing satisfactorily. Mosfet is a 3 terminal semiconductor device used in a wide range of electronic circuits. It works like a JFET but has less current leakage owing to an oxide insulation between the conductors. Mosfet is a good choice for building linear amplifiers owing to its lesser load, and any amplifier made using it is called a Mosfet amplifier.

These amplifiers have a wide range of applications, they can be used in many circuits. Note: This article will be modified with new versions of Mosfet amplifier circuits in future; we shall notify new additions to our home page.

This article contains the following list of amplifier circuits using Mosfet. This circuit is an audio amplifier capable of delivering a decent output power with a minimum no: of parts, with considerable sound quality. This tiny circuit can deliver a whopping 18Watts into 8 Ohm speaker or 30W into a 4 Ohm speaker.

To get such a good performance and stability out of few components, a high quality well regulated DC power supply is necessary. This is very essential for reducing noise and getting a constant output power on varying loads. A good DC voltage regulator able to provide more than 2 Amps 40V can be used. You can expect such a power supply design very soon here in the power supply section. Assemble the board on a good quality PCB.

Use a preamplifier board with tone control prior to this amplifier to get better performance. Single rail supply is seldom used in Class-B power amplifiers. Actually, I got this circuit from an old cassette player that is still working and I am publishing it as it is.

Transistors Q1 and Q2 are wired as a Darlington pair works as the preamplifier. Preset R3 controls the quiescent current while R2 provides feedback. The output is coupled to a speaker through capacitor C4. Capacitor C5 is the power supply filter and C2 is the input DC decoupling capacitor.

The first stage of the amplifier is a differential amplifier based on transistors Q1 and Q2. Capacitor C8 is the input DC decoupler, R1 limits input current and capacitor C1 bypasses unwanted high frequencies. The second stage is the driver stage consisting of transistors Q3 and Q4. The output is coupled with the speaker using the inductor L1. The network comprising of R15 and C5 is meant for noise reduction.

Capacitors C6 and C7 are power supply filters. Preset R6 is meant for adjusting the quiescent current. Hello, would it be okay to use this design for an academic paper? We are doing research for a senior design paper for our undergrad degree in electrical engineering and we need an audio power-amp circuit. Please let us know if this is alright with you. How about it?

Hi Ramesh any transistor is a current amplifier. If current gain of a transistor as per data sheet is say at 1Amp. You require a base emitter current of 10 mA, to have the conduction of 1 amp through collector and emitter. The transistor cannot generate current it can only vary its collector emitter resistance to achieve the required current flow through collector emitter junction as per base emitter current bias.

Is it missing or not needed for some reason maybe the diff amp? I have A 50 Watt 6 ohm subwoofer with 5 speakers 50 watt 5 ohm each.
