DIY: AMB Lab Mini3

Recommended Posts

Received my LM4562MA, removed the AD8397.

 

OMG, 2 PCB track came out :cry:

got to use tiny little jumper to solder the LM4562MA on the PCB.

 

Luckily, my Mini3 still works well :grin:

 

AMB Mini3 with LM4562MA, current rating 15mA, which means 170mAh battery can last about 10hrs :)

 

It sounds very detailed, a bit too detailed and cause harshness in high..

great for monitoring purposes instead of easy listening :party:
