This is the first proto-type, this is not a production unit, this was made so we could have it tested.

Please keep in mind this heatsink will change this was for testing purposes only.
We will also include the Black PCB, same silver treatments over the gold and the power terminals will be 1/0 not 4G

scale power.)
Short Circuit:Full rated power short circuit protect test: passed.
Full rated power long last short circuit test: 10 minutes passed.
Over temperature:Limit output power while inner temperature reach 167 degrees F, protect while inner
temperature reach 185 degrees F.
Low voltage:Protect while power supply voltage lower than 7.8V.
Power limit / Clip limit.Clip limit while THD+N≥1%.
Power limit while inner temperature over 167 degrees F.
Bridge methodHF-1000.1 can be bridged with same amplifier through single RCA cable.
All the adjustable functions on slave amplifier will follow master once be bridged.
