CABINET PLACEMENT
The placement of your cabinet can also have an impact on the amount of
bass it produces. Placing the unit on the floor increases the amount of Bass
you get by an additional +3dB . With each additional wall surface placement
you get another 3 dB increase. This is due to the reinforcement of bass
frequencies by the adjacent surfaces.
The absence of reinforcing surfaces is the reason why outside settings are so
problematic for bass amplification. A system that may be perfectly adequate
in a fairly large club can be rather disappointing on an outdoor stage. If you
have plans to perform in such a setting and are not confident that the P.A.
system can provide you with sufficient reinforcement (both out front and via
monitors), you should consider using additional equipment to support your
own sound.
OTHER CONSIDERATIONS
Suggested Speaker Systems – Your extension speaker system(s) should be
chosen to accommodate the characteristics of your amplifier and your
predominant application. If you will generally be using a single extension
cabinet, it should both be 8 Ohm models so the combined impedance will be
4 ohms. If you are uncertain about your future needs, always go with the 8
Ohm speaker option so that you can add another speaker later if you need to.
In general, adding more speakers will give you a greater volume increase
than adding a few more watts.
We have designed our amplifiers to operate safely at 2 Ohms only because
everyone else is doing it and some users expect it. However, we much prefer
operating at 8 or 4 Ohms because of the markedly improved quality of tone
and dynamic response. But if you really want to, you can operate your CXC
amplifier at 2 Ohms without worry.
Headphone Jack as a Line Driver – On some occasions (such as high-
volume or outdoor situations) it may be desirable to use the CXC combo
along with an additional power amplifier and added cabinets. A standard
shielded instrument cable may be used to connect from the headphone jack
of the unit to an unbalanced input of a standard power amplifier. This will
provide a signal that is post-EQ and after the Master Volume control,
allowing the entire system to be controlled from the CXC combo. This way,
you only have to adjust one set of knobs. This is a Really Neat Thing, huh?
