Package included:
1Pcs Bluetooth Amplifier
Product question:
1. Amplifier board has current sound and noise .
Most of our amplifier board use DC power supply. The board itself does not produce current sound and noise.
The main causes of current acoustic noise are:
A, The power supply filter used is not good; the current sound is caused by wrong input by the power or audio input.
B, The input signal quality is poor; the output of the device connected to the input is improper, and the noise is caused by the abnormal input of the audio source.
C, The input cable is of poor quality; the line is in poor connect; the wiring is damaged; the wiring is suspended
D, The input connection has other playback devices, and some devices share the power supply to cause noise.
2. No sound output, no sound in 1 channel
A, The speaker is broken, or the speaker cable is not connect well.
B, The input cable is not in good connect; the wiring is damaged; the output of the device connected to the input is improper.
3. Volume broken and breaking sound when turn loud?
A, The power input is insufficient, confirm the wiring is correct first, and the supply current is sufficient,
B, The speaker itself has poor performance or damage, and the speaker power is too small or too large.
C, left and right channel speakers (+) (-) output are independent, can not be connected to each other
4. Speaker broken sound when subwoofer amplifier volume turn loud ?
A, The power input is insufficient, first confirm the wiring is correct, the supply current is enough
B, Whether the power of the speaker itself is too large or too small, or the bass performance of the speaker itself is poor; the structure of the speaker box; these abnormalities will cause breaks.
5, The volume power is not enough?
Power and power supply voltage, the amplitude of the sound source signal, the size of the speaker impedance are all related, any kind of deficiency will affect the power
6. Will the amplifier be burnt?
A, The positive and negative poles of the power supply are connected reversely; the power supply voltage is too high, exceeding the limit operating voltage of the board
B. If the board requires a DC power supply, it is not allowed to connect directly the AC transformer power supply (this can be rectified and converted to DC power before it can be used)
C. To confirm that the wiring is correct, then connect with the power supply. The wrong line connected or the short circuit both will cause damage to key parts!

Усилитель дошёл за 5 дней транспортной компанией которая ещё и предложила доставить до порога дома. Супер. Отправлено в день заказа. Что касается самого усилителя, качество сборки отличное, флюса и прочих косяков на плате нет, пропаяна отлично. Работоспособность проверили сразу, блок питания использовали от ноутбука, просадка и перегрева нет. Гоняли и акустику и саб, как на 8 так и на 4 Ома. Для домашней каустики подойдёт отлично. Проверяли так же авто акустику на 4 Ома (Dl Audio 165/ Pride Ruby Voice 8) шатает конкретно, таких показателей по мощности не ожидал от такого усилителя. Щелчков при переключении линий или включении питания на акустике нет, что касается комментаторов менявших кондеры из-за качество звучания, то это уже усилители других классов. За эти деньги плата даёт все что от неё требуется или даже больше.

All OK. Sent and arrived very fast

Delivery from Russia 6 days. Turns on without clicking. From Bluetooth is not phonite. Speakers S30 when powered 19v 4.7a play normally. Subwoofer for 30W 4ohm wheezing. The subwoofer for 10W 4ohm was pumped. To do this, the amplifier needs 24v. Thermal paste was put a lot. The slice of the LF is weak, the voice is heard. HF cuts off normally. Through aux did not check.

Came quickly enough, 10 days to Khabarovsk in Russia. On the back of the board there is a little flux left. Plays well, there are almost no noise, but through Bluetooth a very phonite subwoofer. Badly grounded krutilki, when touching there is a crack on the speakers, but everything is solved by the installation of the caps. I’m happy with the purchase.

Воткнул саб от домашнего кинотеатра и колонки от микролаб про 3.Звук намного лучше стал. Громкости за глаза! Блютуз работает. Чтобы переключиться между блютуз и аux надо нажать на крутилку громкости.Термопаста была но я всë равно своей намазал) Кароче заказом доволен, более чем) Если что дополню отзыв. Рекомендую.

Columns 25 watts with sabs like 60 watts, in each column, copes. These are the columns from the musical Cetra large. But judging by the fact that on 24 volts and the maximum volume of the column did not “break” I think it’s real the value on which the amplifier is capable. But this is a wonderful result, I’m happy for this and took.

It’s coming, it’s working. On good acoustics did not check, but a small system 2.1 works norms. Packed well. No leads. When switching to Aux, there is a voice “liain in”. Click when on, and power off, quite strong. It’s all right. Very bright signal source indication led.

The goods came correct everything works, the fee is clean, there is no flux, all the inscriptions on the board are normal, to the Sabu you can passive filter LF to collect more to put, it came by cdek in 2 days, but the seller himself though gave out the track, but did not go to send goods of the day 4, well, forgive me, After New Year’s Eve, 5 stars, as it sounds, connected to microlabov columns, I would give 4 out of 5 as a music lover, this is the same class D with all the resulting any such amplifier!
O***n –
работает, слышен небольшой фон, и самое главное он выдает моно звук, т.к. средний регулятор по инструкции отвечает за балланс левого и правого канала, выворачиваешь его влево звук пропадает а вправо поёт. и ещё блютуз с телефоном конектится без проблем, а телевизор его невидит невкакую!

В пути 9 дней, доставка СДЭКом до двери. Раскачал от комп.бп 2 колонки от древнего Кенвуд и саб от дом.кинотеатра ЛыЖи не напрягаясь. Саб от Свена (в котором собрал) оказался слабоват, буду вкорячивать в корпус от ЛыЖи. Звук в целом очень приличный для такой крохи. Однозначно стоит внимания.

Everything is fine. The assembly is normal, in a couple of small places will not wash the flux, termpoststa namazyukan. Connected while for a sample to the laptop BP 19.3 V/2.37a, plays powerfully. Stereo present. The truth is all the same just necessary for him BP at 24 V/4A without Saba and 8-9a with SABB. In my case, without a sub on the specified BP, there is still half the volume, but it starts to choke on 50 w/6 ohm speakers .. In general, I’m happy.

При включении -включается блютуз, приходится каждый раз переключать на AUX.
Лучше если было-бы наоборот. А так аппарат рабочий пока.
До этого был такой-же но без Блютуза, что в полне устраивало, и включался сразу AUX.,правда проработал всего неделю. Пришлось заказать второй. Заказал с России, с Москвы до Москвы шол неделю.

The Power gun. Quality assembly, quite clear sound, no background noise in the speakers when the music is turned off (if normal wires are used, of course), normally filters the LF, Bluetooth is working. They delivered faster than the wind, I did not have time to finish the case yet. Definitely justifies his money.

Those who write that the amplifier is mono-! The average swivel is not a balance, but a volume of HF/midrange speakers. The parcel came quickly. The radiator was not completely twisted. There was even a thermal paste under the radiator, but it was everywhere, so it had to be washed and smeared in normal. After assembling, the amplifier plays normally. Well, as far as possible for one and a half cosars.

Everything is fine, the description matches. Connected, works norms, from 12 volts acoustics 4 ohms 30 W kicks up to overload. Stereo (do not believe those who write that it is mono). The subwoofer is also good at shaking. One (personally for me) flaw-by default Bluetooth turns on, I also need aux, I have to switch mode at each turn on. Otherwise, everything is fine.
In Kiev it came in about a month, the packing is normal, the box is corrugated cardboard, pupyrka, polyethylene, envelope.
In general, I recommend!

Tried to connect different power supplies, about 4 different kinds and Volts from 12 V to 24 V. I can hear the hissing in the columns. And I noticed that the sound through aux plays much quieter than through Bluetooth.

усилитель хороший, но есть ложечка дегтю на бочку мёду, это пердёж в левом и правом канале при включении, на сабвуферном пердеж отсутствует.
нужно будет схему задержки на включение акустики собрать.
несоответствует форма описанию, видимо релиз платы другой, ралиатор общий и крепится тремя болтами, на рисунке их два отдельных.
впринципе пойдет.

4 дня отправки, 2 дня доставки) по звуку классный усилитель, но требователен к питанию, так как запитав от импульсного бп на 24в 5а есть и хлопок при включении и лёгкий еле слышимый фон в простое, по мощности по 40вт на канал точно выдаёт ибо раскачал мои свен роял 2. Один нюанс – почему то не положили 1 пластиковый колпачек на крутили, а так посмотрим сколько проработает, пока неделю полет нормальный!
