System Block Diagram
1. 300W 16 Ohm Parallel 1/4" Jacks:
Connect the output of your amplifier
(rated up to 300W into 16 ohms) to
one of these jacks using good quality
(non-shielded) speaker cable. Never use
(shielded) instrument cable to connect
speakers to an amplifier.
You can use the other jack to connect
a second Blackheart BH412SL or
BH412ST speaker cabinet in parallel.
This will present a total load of 8 ohms
to the amplifier (maximum power input
= 600 watts rms into 8 ohms).
