About Super Mini Bluetooth Speaker This is possibly the worldʹs smallest in size Bluetooth speaker with incredible clarity of sound and volume. User Manual AFTER SALES SUPPORT IRE INSTRUCTION MANUAL Super Mini Bluetooth Speaker Version: V3.0 1. Refer the below mentioned link for the same.Ġ3. Method 1: Check to see if you have run the Hardware and Devices Troubleshooter. Let’s try these methods and check if it helps in fixing the issue. This issue might occur if the Bluetooth drivers are not updated or services are not started. What is the make and model number of the computer?Īre you able to use this BT speaker on different computer? Assuming +/- 40 V power supply, 4 ohm load and 200 watts delivered to that load:What is the exact/complete error message you receive while connecting BT speaker? I suspect there may be heat dissipation considerations.

Having said all that, I would hope someone with real experience doing this kind of calculation can come along and either tell me I'm full of crap and teach me how to actually do this kind of calculation or confirm I'm sort of on the right track here. So the power dissipated in the chips is 23.4 volts times 7 amps or around 164 watts. The current through the load is ~ 7 amps. So that gives us 56.6 volts across the load, leaving us with 80 (total supply voltage) - 56.6 volts or 23. We do have a plus minus power supply so to continue, I believe that we need to account for both the positive and negative side of the waveform, so I multiply by 2. Now that is the DC equivalent voltage not peak to peak or even plus to minus. The RMS voltage across the load is ~ 28.3. Assuming +/- 40 V power supply, 4 ohm load and 200 watts delivered to that load: Click to expand.I suspect there may be heat dissipation considerations.
