Item came today but with NO documentation & your web page is little help either.

REgarding the TOP/FRONT of the device:
Q1: what is the VOUT [tiny solder holes] for? Is VOUT same as V-In
Q2: DC 12-24v power in? What watt/amp is needed? 300mA or 2A or ???

RE: BACK image on your web page
Q3: How to obtain MONO output,
Web says S1 open; S2-6 On I assume you melt the solder holes together ( o o ) ?
Q4: and then do I use L or R output terminals for the mono output?

You REALLY need to mark the board better OR have more info on your web page OR print an insert to answer these questions.

Hi Jimbo213Mo,
Thank you for your suggest, this is DIY　product, we will make it better and better.
Here is answer for your questions.
Q1. 5V / 150-200mA for bluetooth receiver
Q2. When the power supply is over 12V/3A, please use 4 Ω/15-30W for left and right speaker; When the power supply is over 19V/3-4A, please use 4 Ω/30-50W for left and right speaker;If you need a high power, we suggest that you should use a power supply with over 20-24V/4-5A and use 4Ω/40-80W for left and right speaker.
Q3. 2 soldering points of S1 open(desoldered), 2 soldering points of S2-6 need to be soldered.
Q4.There are no differences between left and right speaker when you set it mono.
Hope this will help you.
