Options
Twin part configuration
The ability enter can use a DG plug or a terminal block. As well as, the audio enter can be geared up with two enter terminals, which can be utilized with 3.5 audio jacks or 3P plugs
Good array aspect configuration
Filter inductor array
The inductor coil has a limiting impact on AC. It will probably kind a high-pass or low-pass filter with a resistor or capacitor, a section shift circuit and a vibration management circuit. The six inductors kind an array with excellent results
European terminal blocks
It’s manufactured by European requirements, has superior flame retardancy, security, environmental safety, and is totally appropriate with floor packaging expertise. Selecting massive terminals just isn’t solely a consideration of energy, but additionally high quality
Army grade PCB
1.6mm thick double-layer circuit board, RF-4 dense glass fiber materials, easy floor, excessive mechanical power, warmth and moisture resistance, not straightforward to crack within the part, excessive dielectric properties, good sound high quality will probably be excellent when the fabric is nice. The format of the circuit board is gorgeous, the parts are chosen, and the chip expertise is adopted. Every plug-in is professionally hand-soldered, and the method is carried out with out the flawed expertise of the workshop.

M139 tuning board utilization situations
Join your cell phone and laptop at will
The ability amplifier chip derived from TPA3116D2 will launch the expertise of tone energy amplifier. This energy amplifier has excessive pure digital decision, twin configuration of energy provide and audio, and it’s handy and fast to connect with laptop and cellular units.
Residence theater sound subject management
M139 tuning board, the utmost energy of the subwoofer is 100W, with stereo adjustment, it will probably produce a surprising sound subject and take you to the scene. As much as 1.2MHz switching frequency, better than 90% energy effectivity, your best option for tuning boards
DIY audio speaker
The ability is massive sufficient and the sound high quality is excellent, it’s value DIY adjustable audio system. Those that like bass can be utilized, and people who like treble may also be used, satisfying numerous public and residential audio-visual experiences
Listed here are a number of widespread causes of noise
{hardware} downside
Typically, the ability provide and the ability amplifier needs to be saved at a sure distance to keep away from electromagnetic interference. It’s best to make use of a high-quality energy provide, and the ability provide will probably be extra steady. If an influence provide similar to a transformer is used, with a purpose to forestall electromagnetic interference, it’s best to cowl the transformer with an iron cowl. Following are widespread downside:
1. The ability provide is unstable, or the ability provide module produces interference
2. The impression of utilizing a switching energy provide as an influence provide
3. Use a transformer for energy provide with out shielding and isolation to keep away from interference
4. There’s electromagnetic interference within the use setting
5. There’s a downside with the audio enter gadget itself
Software program downside
Audio driver settings have an effect on and participant particular results
Every energy amplifier chip has its personal distinctive sound subject. If the sound card driver or playback software program is ready with sound results, it is going to instantly have an effect on the sound high quality of the ability amplifier board. The simulation results of some particular results software program may trigger distortion of the ability amplifier. It is suggested to show off the related particular results software program or sound card driver particular impact settings when connecting to a cell phone and laptop, after which use the particular results after making certain that the output impact of the ability amplifier just isn’t affected.
Ideas
1. There will probably be ample output energy solely when the audio enter is ample and the ability provide voltage/present is ample. The upper the ability provide voltage, the upper the relative energy, and audio system with completely different impedances can have completely different output powers. Within the case of ample voltage and present, the bigger the horn ohms, the smaller the relative sound energy, please concentrate!
2. Don’t join the ability provide and audio system indiscriminately, and use the information supplied within the product description for an affordable mixture. Unreasonable use of energy, voltage, and speaker wattage could trigger harm to the board.
