ULTRASTACK BG412V
Dear Customer,
welcome to the team of ULTRASTACK users, and thank you
very much for expressing your confidence in BEHRINGER
products by purchasing the ULTRASTACK BG412V. Even though
hooking up and operating the BG412V is very easy, we would
still like to provide you with a brief description of this excellent
speaker cabinet and its features.
+ The ULTRASTACK can produce extreme sound pressure
levels. Please note that high SPLs do not only result in
listening fatigue but can also permanently impair your
hearing.
s Please turn off the amp and disconnect it from the mains
before connecting it to the speaker cabinet.
+ Turn off the amp before changing the ULTRASTACK
settings.
s Select stereo or mono operation and set the switch
accordingly:
Set the ULTRASTACK to MONO to drive it from a single
power amp. In this case, the speaker cabinets impedance
is 4 Ohms. Use the ULTRASTACKs INPUT connector to
connect the speaker cable.
If you have two amplifiers or a stereo power amp, you can
operate the BG412V in two-channel mode by setting the
ULTRASTACK to STEREO. Then, the speakers impedance
is 2 x 8 Ohms. Connect the left channel of the power amp to
LEFT, and the right channel to RIGHT.
s When connecting the BG412V to a tube power amp, please
use the corresponding output(s) on your amp or set the
impedance selector switch to the correct impedance after
disconnecting the amp from the mains.
+ Be sure to set amp impedance accordingly.
+ Disconnect your amp from the mains before changing
the impedance settings.
+ Never use guitar or similar cables to operate the
BG412V. Always use speaker cables with a minimum
diameter of 2.5 mm (10 AWG).
+ Never operate a tube amp without a load connected to
it. If the impedance of the connected speaker cabinet
fails to match the amplifiers impedance, the amp could
be damaged. Please refer to the operating instructions
accompanying your amplifier.
