Q: How do you control the output speaker volume

Asked by BG150233234 on 2021-10-08 03:38:31

PINTO It is not possible to program the volume in this module, except in the settings of the device that sends the signal. This is something missing. Which is unfortunate and no one I know really understands this process. In fact, the problem you have in this module is related to the module's Gain structure and it is not possible to satisfactorily resolve this issue. I bought one of these modules and the subsequent decision I made was simply not to buy any more Bluetooth amplifiers (MH-M38). I only buy the MH-M28, which works properly, adding it to a normal amplification module. Hope I was helpful. Best Regards. Macedo Pinto Portugal

PINTO I am satisfied with the purchase of the two oximeters I made here at Banggood. Both are working in the right conditions, the results obtained in the measurements are still very similar to those obtained in a reference oximeter. Therefore, these oximeters appear to work well. I hope they continue to justify the investment I made. A very positive point is the ease of viewing results. Another point that I highlight is the consumption of electrical power (battery) absorbed, which is quite balanced, unlike some oximeters that I know well.For the above I recommend that anyone who needs a minimally reliable oximeter to buy it here at Banggood.Thank you, Banggood Team.Macedo PintoPortugal

PINTO I just finished two different assemblies, using this microphone preamplifier and the results obtained are very positive. I think these preamplifiers are very well designed and in certain circumstances turn out to be surprising. One aspect that I must highlight is the ease with which a personalized setup is made, including the possibility of turning the AGC function on / off.I think this purchase was very positive, since both preamplifiers are working properly. For those who do not need the basic configuration, just remove the capsule from the microphone and you have an excellent preamplifier for generic service, at a very good price.I recommend your purchase here at Banggood, without a doubt.Macedo PintoPortugal

PINTO Thisspeaker protection works perfectly. I am satisfied with the result and it is quite possible that I will be ordering more cards of this type, knowing that I can trust them. Warning to those who buy this card: The earth circuit is common to both channel relays (Left
