Unfortunately still missing (had another mini amplifier ordered) the description of the connections.
Neither on the circuit board, nor as Beipacktzettel or packaging.
Have this can only find out by other product of identical items ...
When current I even traded on the off chance, pray and plug: plug's like laptops (round with thorns in the middle) - the positive pole is the middle ;-)
But what then really constituted the 1 star deduction, was a slight noise in the high frequencies. very quiet, but audible at 50 - 75% volume level. At about 75% volume it's gone then, or is drowned out. Affiliated to the test:
- 1 LS Visaton FR 8 8 ohm
- MP3 player Sansa Clip SanDisc
Both were also to other amplifiers ('m still a) tested - no noise.
Conclusion:. For the price absolutely OK Would I buy it again, because I always hear only full Lautstäke ;-)
Notice: long delivery time, because of Hong Kong, but before the deadline! Support for patient people, but then inexpensive beautifully.
