Dear Customer,
Welcome to the team of BUGERA users, and thank you very much for expressing
your condence in BUGERA products by purchasing the BUGERA 412H-BK.
Eventhough hooking up and operating the 412H-BK is very easy, we would still
like to provide you with a brief description of this excellent speaker cabinet and
itsfeatures.
◊ The BUGERA 412H-BK 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.
• Please turn o the amp and disconnect it from the mains before
connecting it to the speaker cabinet.
◊ Turn off the amp before changing the BUGERA 412H-BK settings.
• Select stereo or mono operation and set the switch accordingly:
Set the BUGERA 412H-BK to MONO to drive it from a single power
amp. In this case, the speaker cabinet’s impedance is 16 Ohms. Use the
412H-BK’s INPUT connector to connect the speaker cable.
If you have two ampliers or a stereo power amp, you can operate
the 412H-BK in two-channel mode by setting the BUGERA 412H-BK to
STEREO. Then, the speaker’s impedance is 2 x 8 Ohms. Connect the left
channel of the power amp to LEFT, and the right channel to RIGHT.
• When connecting the 412H-BK to a valve 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 412H-BK. Always use
speaker cables with a minimum diameter of 2.5 mm (10 AWG).
◊ Never operate a valve amp without a load connected to it. If the
impedance of the connected speaker cabinet fails to match the
amplifier’s impedance, the amp could be damaged. Please refer to the
operating instructions accompanying your amplifier.
