It turns out that the 2 x15W is only possible using 4 Ohm speakers and a small heatsink on the IC. I don't have 4 Ohm speakers so I settled for 2 x 10W with my 6 Ohm speakers. The Class D amplifier has received a lot of negative press from "serious" listeners, but to my low-spec ears it sounds great and loud! Using an MP3 player also means that you don't need to have bass, treble and balance controls on your amplifier - just a volume control.

Since the wiring-up is so simple, I thought it would be a great medium level project for beginners. Besides these you will also need multistrand 7-strand hook-up wire various colours for the interconnection of the components. Attached is a PDF with very detailed explanation of each of the parts in the parts list. I wrote this mainly for beginners, so if all you need is the parts list, you can skip most of it and just read the part on the AC Adaptor - very important.

In this project there is a minimum amount of mechanical work. Only three basic tools are needed for making holes and one tool for soldering:. You start off with a 3mm hole at the centre of the position that you want to mount the component, insert the reamer and push forward gently while rotating clockwise. After every few turns, check if the component fits snugly in the hole.

With practice you will be able to make holes quickly and accurately. All I can say is practice makes perfect. This is a surface mounted PCB, so be very careful.

Avoid splashing solder. One solder splash can short a number of components together - almost impossible to recover from. Stick blank white stickers on the surfaces on which you are going to mount your connectors and controls. In my case I decided to have a front and rear - like a full sized amplifier. I marked out where each control would be see the pictures.

The sticker provides a clean white surface for making clear markings and also protects the surfaces from scratches while drilling, etc. Next, using the hand-drill, drill the pilot holes with a 1mm drill in the places where each control comes through.

Finally enlarge the holes with the Reamer following the guidelines in the previous section. The results are shown in the pictures above - absolutely neat holes with no further cleaning up to be done.

As you can see from the picture with the components mounted, all the components are screwed in except the speaker terminals which are super-glued to the box after passing the leads through the 1mm holes. Make sure that the terminal holes in which the speaker wires are inserted point upwards for easy connection.Sign in.

Sunshine co. Sincere Company Store. All Electronicsfreeshipping Store. TZT Official Store.It can be used in any DIY or audio-related projects for cost and board space-saving purposes. It is more efficient in terms of power than the other competitors ' ICs. Note : Complete technical details can be found in the PAM Datasheet linked at the bottom of this page. The important ports on the amplifier board are shown below. As this amplifier is a stereo amplifier, it has a stereo input and stereo output pin port where the output speaker can directly be soldered.

The maximum output power is 15W per channel. It also has an additional feature of mute switch functionality, which is very usable. The mute switch can be used to mute the power amplifier output when the switch is pressed or the mute port is shorted. It does not require a heatsink, which also saves additional board space.

Irrespective of the heatsink, it could also provide thermal protection which is another essential feature for such a small wattage amplifier module. The interfacing of PAM is quite easy.

PAM can be seen as a "big brother" of PAM in the sense that their sounds appear somewhat similar.

Anyone Can Make This 10W+10W Amplifier

PAM is, with 2x8 Watt in 8 Ohm, clearly more powerful than PAM and has the margins to be used as an amplifier for daily use with two- or three-way loudspeakers. It can provide a sufficient sound level from book-case speakers without risk of noticeable distortion.

The PAM could benefit from a 50Hz high-pass filter at the input such that power for the deep bass does not become a limiting factor. PAM has a rich sound with no significant hiss.

So, for DIY purposes the chip should be acquired in a board where only the peripheral components may be modified. With only 20mA quiescent current the idle losses are below mW. Such can easily be handled by a heat-sink glued on top of the PAM The chip is found in minimum-configuration modules with only the most essential peripheral components and in boards also including a supply-line decoupling capacitor, a volume potentiometer and connectors.

Both types are sold at very attractive prices. Two specimens of a more complete board were prepared for test. One of those was bought at about 5 times the price of the other so attention has to be used in purchase.

A particular issue for that module is the value of the boot-strap capacitors used. The PAM data-sheet recommends use of 1uF boot-strap capacitors. But, a member of the diyAudio forum believes that less is used for that board and should be replaced with 1uF capacitors.

Else, the bass performance will be affected. For that reason the two boards tried here were modified as recommended on the forum, before test. It is necessary to remove the big uF decoupling capacitor before replacing the two boot-strap capacitors located at the foot of the decoupling capacitor. The two other boot-strap capacitors are located on the opposite side of the PAM It is recommended to remove the initial boot-strap capacitors first and then mount new 1uF SMD capacitors.

As it can be seen from the photo, the new bootstrap capacitors are physically bigger than the initial ones. In the board to the left the boot-strap capacitors are marked with C8, C9, C18 and C19 and are the initial ones.Heat sink is required for high power output. Does It matter if I chose a 50v uf electrolytic capacitor or a 35v model. Or is a noteer model needed? If you feed the pam board with 12 volts dc, you need capacitor voltage value at least 16 volts.

Using high voltage rate capacitor doesn't effect sound quality and make the cap's life longer but the higher voltage model cost is higher. Hi, I'm having problems with this amplifier and I saw your video, could you help me please? Provide me some information. Normally, if you play loud music with deep bass with low impedance loudspeaker, you amplifier work hard and may activate built-in thermal protection.

I am also having the same problem. I am using The first solution is easy to check, lower bass in equalizer and test again. Post a Comment. As you can see in my video that the amp board require only one uf electrolytic capacitor for supply decoupling to eliminate hum from switching power supply some ic amplifier require uf to eliminate hum from the power supply.

The sound stage is wide but space between instrument not precise. Popular posts from this blog How to connect volume control to an amplifier - July 08, I think so many people who want to start an electronic project must know this basic wiring too, I hope this wiring diagram will help an electronic DIYer like me.

Volume control principle is a signal divider, the more volume control output yellow line near input signal source pink line the most signal flow to an amplifier. Read more. TDA A is an audio power amplifier IC that has 5 watts output power with 8 ohms speaker and 3 watts with 16 ohms speaker.

The IC is simple to wiring and needs only 6 external components to make the amplifier working. TDA A working with a power supply between 4.

TDAA has a built-in DC volume control so you can control the gain of the amplifier by changing voltage value at DC volume control pin by use a potentiometer. DC volume control makes you connect the audio signal directly to the amplifier input so it makes a sound more transparent and cleaner than a normal amplifier.

I think it's a good question so I will explain it here. What is a power supply filter capacitor? It is the capacitor that used to filter AC ripple from DC power supply present to amplifier board.

Below pictures are the place that you add power supply capacitor. Hall effect sensor switch is a switch that turns on when enough magnetic field near the IC.Some researchers use quantitative methods to exclude outliers. In some areas of research, such "cleaning" of the data is absolutely necessary. For example, in cognitive psychology research on reaction times, even if almost all scores in an experiment are in the range of 300-700 milliseconds, just a few "distracted reactions" of 10-15 seconds will completely change the overall picture.

It should also be noted that in some rare cases, the relative frequency of outliers across a number of groups or cells of a design can be subjected to analysis and provide interpretable results. For example, outliers could be indicative of the occurrence of a phenomenon that is qualitatively different than the typical pattern observed or expected in the sample, thus the relative frequency of outliers could provide evidence of a relative frequency of departure from the process or phenomenon that is typical for the majority of cases in a group.

Correlations in Non-homogeneous Groups. A lack of homogeneity in the sample from which a correlation was calculated can be another factor that biases the value of the correlation. Imagine a case where a correlation coefficient is calculated from data points which came from two different experimental groups but this fact is ignored when the correlation is calculated.

Let us assume that the experimental manipulation in one of the groups increased the values of both correlated variables and thus the data from each group form a distinctive "cloud" in the scatterplot (as shown in the graph below). In such cases, a high correlation may result that is entirely due to the arrangement of the two groups, but which does not represent the "true" relation between the two variables, which may practically be equal to 0 (as could be seen if we looked at each group separately, see the following graph).

If you suspect the influence of such a phenomenon on your correlations and know how to identify such "subsets" of data, try to run the correlations separately in each subset of observations. If you do not know how to identify the hypothetical subsets, try to examine the data with some exploratory multivariate techniques (e. Nonlinear Relations between Variables.

Another potential source of problems with the linear (Pearson r) correlation is the shape of the relation. The possibility of such non-linear relationships is another reason why examining scatterplots is a necessary step in evaluating every correlation.

What do you do if a correlation is strong but clearly nonlinear (as concluded from examining scatterplots). Unfortunately, there is no simple answer to this question, because there is no easy-to-use equivalent of Pearson r that is capable of handling nonlinear relations. If the curve is monotonous (continuously decreasing or increasing) you could try to transform one or both of the variables to remove the curvilinearity and then recalculate the correlation.

Another option available if the relation is monotonous is to try a nonparametric correlation (e. However, nonparametric correlations are generally less sensitive and sometimes this method will not produce any gains.

Unfortunately, the two most precise methods are not easy to use and require a good deal of "experimentation" with the data. Therefore you could:Exploratory Examination of Correlation Matrices. A common first step of many data analyses that involve more than a very few variables is to run a correlation matrix of all variables and then examine it for expected (and unexpected) significant relations.

For example, by definition, a coefficient significant at the. There is no "automatic" way to weed out the "true" correlations. This issue is general and it pertains to all analyses that involve "multiple comparisons and statistical significance.

Pairwise Deletion of Missing Data. Only this way will you get a "true" correlation matrix, where all correlations are obtained from the same set of observations.

However, if missing data are randomly distributed across cases, you could easily end up with no "valid" cases in the data set, because each of them will have at least one missing data in some variable.

The most common solution used in such instances is to use so-called pairwise deletion of missing data in correlation matrices, where a correlation between each pair of variables is calculated from all cases that have valid data on those two variables.

However, it may sometimes lead to serious problems. For example, a systematic bias may result from a "hidden" systematic distribution of missing data, causing different correlation coefficients in the same correlation matrix to be based on different subsets of subjects. In addition to the possibly biased conclusions that you could derive from such "pairwise calculated" correlation matrices, real problems may occur when you subject such matrices to another analysis (e.

Thus, if you are using the pairwise method of deleting the missing data, be sure to examine the distribution of missing data across the cells of the matrix for possible systematic "patterns. If the pairwise deletion of missing data does not introduce any systematic bias to the correlation matrix, then all those pairwise descriptive statistics for one variable should be very similar.

However, if they differ, then there are good reasons to suspect a bias. For example, if the mean (or standard deviation) of the values of variable A that were taken into account in calculating its correlation with variable B is much lower than the mean (or standard deviation) of those values of variable A that were used in calculating its correlation with variable C, then we would have good reason to suspect that those two correlations (A-B and A-C) are based on different subsets of data, and thus, that there is a bias in the correlation matrix caused by a non-random distribution of missing data.

Pairwise Deletion of Missing Data vs. Another common method to avoid loosing data due to casewise deletion is the so-called mean substitution of missing data (replacing all missing data in a variable by the mean of that variable). Mean substitution offers some advantages and some disadvantages as compared to pairwise deletion.And blow-drying her hair at the same time.

Some plumbers are licensed by the state, others by the counties they work in. Check with your local city hall or chamber of commerce. They should be able to direct you to the appropriate source for a list of licensed plumbers in your area. They come and go. Instead, look for a plumber who is well-established in your community. Check the Better Business Bureau and read customer reviews at sites such as HomeAdvisor, Angie's List, or Citysearch. Local contractors or plumbing fixture stores can also refer you to a quality plumber, according to Grady Daniel, who owns a plumbing company in Austin, Texas.
