This amp features 4 channels using the two tc2000 and two sta508 (2 x TK2050 chipset). It is similar to the T1 amp and deploys the sta508 as output chip in full bridged, non-paralled configuration which produces80W@8ohm and 40W@4ohm. Several boards can easily be connected together to create 8, 12, 16 etc channels.
This amp, unlike the T1, does not have any speaker protection, however, we didn't experience any on/off noises.
The board can only take DC powersupply, no AC. Accepted DC range is 20V - 32V. The smps300r 28V should be able to drive all four channels, but not at 80W constant output, as the smps300r can do 400W peak output and 300W constant. Four channel outputting 80W will draw 400W at estimated 80% effeciency.
Speaker hookup:
Ground on the two channels can not be connected together. It is ok to leave one or more channels unconnected
