Thread starter brittanysmale Start date Jan 3, Search Forums New Posts. Thread Starter brittanysmale Joined Dec 21, 8. Hi there, I am looking to build Bluetooth speakers with tweeters and woofers in parallel for each side, through a crossover. I was wondering if there is a possibility of wiring a potentiometer to control the volume of all four speakers - if so where would they be wired? I have attached a really rough outline of the the circuit beginning to take shape, as it is only beginning any extra advice about where things are not wired properly would be a great help.
Is it possible to connect more than 1 wire to a single spot on the amp board? The amp board is TDA - it has the control buttons, but if it is possible I would prefer the volume knob.
Any feedback and advice would be appreciated. Thank you!! Diagram draft 1. Scroll to continue with content. Dodgydave Joined Jun 22, 9, The datasheet is here. Audioguru Joined Dec 20, 11, Your crossover network with a single capacitor and a single inductor is too simple. The woofer will still shriek high frequencies and the tweeter will be blown up by low frequencies.User Name Stay logged in?

Volume control of TDA board amp? I wonder how would I be able to vary the volume of my music. Any suggestions? You want a 'Dual Gang' potentiometer with each half wired up like this. Use a 10k or 22k logarithmic pot. The outer two terminals of the pot are reversed.

Do I have to specifically mention about the Logarithmic pot? A log pot matches the way our ears work and so appear to give a progressively equal increase in volume per degree of rotation of the control. A linear pot still goes as loud and quiet but the increase in volume per degree of rotation wont seem to match how you perceive the level.
Linear pots tend to match better between the two channels which can be an advantage. You can also fake a log law by adding a single resistor per channel from the wiper middle pin to ground. Thanks for the prompt response Mooly. I have one more question. I am thinking of using TDA board with my old speaker system ss-rs77v which consists of 2 woofers in series and 1 tweeter in parallel to the 2 woofers.
I guess it becomes a Full-range system. As I have read somewhere that whole component is rated at 70 W and also on the back label it's mentioned that it's 24ohm.
Will it be possible to make that work with this amplifier board? It will certainly work but those impedance values are not standard at all. Maybe because they are 'surround sound speakers' and deliberately configured for high impedance to limit the output from them. You might find them quieter than you expect but that is a 'fault' of the speaker, not the amp. So how should I proceed? By Connecting one woofer to each amp output channel?
I recently realized that I am not sure that it is rated at 70 W. If there is just one pair of connections on the back of the speaker then you can feed the speaker normally. I'm guessing this is how they are. If by chance the woofer and tweeter are available via separate sockets on the back of the speaker then you must determine if a cross over is built into the speaker cabinet before applying full range audio to them.
Yes there is only one pair of wire to this speaker box and inside it is as I have described i.
Two woofers in series and the tweeter in parallel and yes a capacitor is already there for crossover so I need not bother about determining capacitance I guess. My queries are as follows 1 Shall I connect these two woofers directly to each channelof the amp? I am assuming each woofer is of 12ohm since whole box is labeled as 24 ohm and woofers are in series.
Correct me if i am wrong. And If at all it causes distortion with 12ohm speaker, will the distortion be significant?Overview page 6 - Features page 7 - Back panel page 8 - Chapter 2. Hardware Detail page 9 - Volume Control page 10 - Chapter 3.

Overview As an ideal Class-D audio power amplifier and integrated with TDA which is currently popular around the world, it not only provides dream sound but also has high efficiency, thus it can dissipate the heat after long-time working to ensure that the amplifier can works in a stable condition for long time. Can be used with most laptop power adaptors. Page 7: Back Panel 1. Page 8: Chapter 2. The output level of both a and b can be adjusted via the volume control knob.
The headphone amplifier output will override the banana socket output automatically. Page Chapter 3. Electrical Characteristics Check if the product has worked for long time or if the audio signal is too high. If it is, sound when turn off the power and turn it on again. If not, correctly connect it to the power according to the schematics. Page Chapter 4. Page Chapter 5.

Cancel Delete.The result will be determined by the number of points accumulated for a specified race by the two named drivers after the handicap has been applied. The Field includes any driver who is not listed. Any drivers who do not qualify for the race will be deemed no action. The race must be run within one week of the scheduled off time for there to be action.
The official NASCAR winner of the race shall be the winner of the race for wagering purposes (this includes all races which are halted prematurely for any reason). In the event of the specified number of laps not being fully completed, all bets will be void. All match-ups will be settled as per the official NASCAR result. If one driver fails to complete the race then the other driver will be declared the winner. Where both drivers fail to complete the race then the number of full laps completed will determine the result.
If both drivers fail to complete on the same lap then the official placing as assigned by the controlling authority will determine the result. Both drivers must start the race (e.
If any driver is replaced before the start of the race then all match-ups will be void. For example, Driver Gordon qualifies in 1st place but due to injury is replaced by driver Brack (all bets void).
If a driver is replaced during the race then bets will stand on his replacement. For example, Driver Gordon starts the race but due to injury is replaced after 10 laps by replacement Driver Brack who then finishes the race and places 4th. In the race standings and for betting purposes Driver Gordon would be credited with a 4th place finish. Race props will be settled on official NASCAR results.
If a race is shortened and no official results are posted then all bets will be deemed no action. For all markets, for customers ease, we will endeavour to grade all wagers at the conclusion of the race on the unofficial result.
However, we reserve the right to alter any wagers which may be affected by the official results as displayed on Nascar. Qualifying match-ups are based on qualifying times (quickest times) and not the starting line-up. For example, positions 37th to 43rd will be decided on times and not on any other criteria.
If two or more drivers have an equal qualifying time then the driver with the higher grid position will be deemed the winner. Bets will be void unless the driver starts the qualifying lap.
If any driver fails to start then bets are deemed no action. In the event of qualifying not being completed then all qualifying bets will be no action. All props will be settled on official NASCAR results unless otherwise specified. All prop futures are deemed action when drivers qualify for at least 27 races.
Outright Drivers Championship will be deemed as action when driver has qualified for at least 27 races. The winner, as deemed by the official ruling body of the race, shall be the winner of the race for wagering purposes.
This includes all races which are halted prematurely for any reason.
