Tips: This link is scattered kit , see friends Detailing third ~ DIY Welding hands !
1 .DIYSuite welding, production, requires that you have at hand the appropriate measurement tools such as welding and installation of iron , multimeter , etc., and have a certain electronic technology and ability to successfully install and use only , we guarantee the package components are brand new original . If you do not have these conditions, please carefully shot !DIYThere unsuccessful risk !Electronic components in the front of the tin, cut legs if quality problems, can return, tin , cut feet, after welding damaged or production is not successful , we do not offer refunds or exchanges ,Thank you for your understanding and support !Because amplifier kit program was developed for the audio plant , rather there is an agreement , the circuit diagram can not be outsourced , not all programs provide schematics , please Amoy Friends of understanding !2.1 three -channel subwoofer amplifier board TDA7379 single supply of spare parts to upgrade two pre- 5532
2.Parts :Delivery of spare parts is an empty plate and a bag equipped with on-board components ,Excluding others such as heat sinks and power or speakers, and other accessories knob.NeedDIYPicture the same friends with yourself and then welding the components correspond to the insertion , after the completion of welding as shown ( some components due to quality improvement needs and different batches , the appearance will be slightly different ) .
Product description:
This kit uses an imported STMicroelectronics (ST) CompanyTDA7379CompositionThreeChannel2.1Amplifier circuit, pre- processing and bass brands using Texas Instruments TI NE5532 dual op amp circuit, fewer external components , flexible to use, features a variety of voltage supply . Single power supply DC10V ~ 22 V( 12V battery power supply can be connected using )AC9V ~ 14VThe range can be input ( input voltage , the greater the output power ) , at least in the current proposal power more than 3A , sound will be better.Were two potentiometers to adjust the bass and overall volume( Non-traditional use of the RC circuit to adjust the bass and treble frequencies via potentiometer on the circuit doing alt processing , bass circuit using a low -pass filter , does not require an additional treble potentiometer ) .
About satellites can pick2 ~ 4 ~ 6 ~ 8Ohm speakers, the subwoofer can be connected4-8Ohm speakers, left and right satellite channels maximum output power can be achieved13WX2,Subwoofer channel can reach the maximum output power38WX1.
KitPCBUse high-quality double-sided fiberglass panels, advanced marked solder layer , rational layout , nice. Fewer external components , no noise , deep and powerful bass , treble and full clear , pristine sound quality . Suitable for cars, motorcycles , electric cars and multimedia audio conversion , improve your sound quality.
Tips: The 2.1 amplifier boardRC by using non-traditional potentiometer to adjust the bass and treble frequencies , so the circuit did alt processing satellite channels , bass circuit using a low -pass filter , so that only the high-frequency satellite channel sound output , no bass frequency output , if be sure to connect the left and right satellite speakers and subwoofer speakers with a total of three satellite channels used about 2.0 audio, do not connect the bass channel to use , then only be able to hear the treble frequency sound ( recommended use, about satellite speaker speaker parameters to be the same . outputs connected correctly applied by the board logoOf ! )
Specifications:PCBLength Width 50MM 90MM
Complete the welding board width is about: 90 * 72 ( including potentiometers handle )
Center distance of about two potentiometers 28.5MM
The package price does not include heat sink included, need to install a heat sink before use , please friend knows
Because each batch of different batches of arrival , there will be a slight difference in the appearance of the board components , images no longer be replaced, mainly in kind , we guarantee to use the same or better quality !
Delivery of spare parts is an empty board and the board is equipped with all the components needed to understand your own electronic technology, and has some ability to complete the installation Oh !Welding is also very simple , PCB board has components logo, just press identification can be inserted into the weld .
This product parts, welding can be completed , work with your hands the ability to have a direct relationship , without providing aftermarket parts installed , please understand , if you need to install the tutorial , please contact customer service Want , thank you !
Welding of the board, the board components into the corresponding position , then the PCB boardOpposite the pin weld
The new version better electrolytic ingredients , C3 C4 also replaced the yellow correction capacitors , better quality !
Complete the welding of the board
The kit can be equipped with a heat sink using small store has a good wire teeth , easy to install
