Finally got around to taking pics of my HellFire 1000.1 Pics & Test Results From Diablo Audio Technologies Forum.

Subsonic Filter Response

Bass Boost Reponse

Bass boost Q control (bass boost frequency set at 50 Hz)

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.

Howd it make the icon sound?

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