Protect Function

Overload:

Protect when output current reach 75A. (Protect when load resistance less than 0.8ohm at full

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 method

HF-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.

With only ~600 Watts @ 2 Ohms,...It sounded great!
