• Remember, the LUNCHBOX
Acoustic
can be loud, and it concentrates a great deal of
sound energy into a small area. Unless you are an unusually soft player, you will probably
have to engage the pad on your mic.
• Using a foam windscreen is also a good idea, since the driver can create bursts of air when
driven very hard.
Understanding Amplifier Power:
Nobody has come up with one number that can fully represent the power capability of a guitar
amp. RMS is a very conservative approach, but it misses the issue of dynamic power and real
world musical signals. At the other extreme, Peak Power can readily be inflated to the point where
it is not a reliable indicator of anything. In fact, the actual power of any given amplifier varies
widely at different frequencies. Every amplifier company has their own procedure for stating the
power capability of their products, which ideally should be done within the boundaries of accepted
technical standards and legal requirements. Here is our thinking on the matter, which we believe
results in specifications that are both conservative and useful.
The internal speaker of the LUNCHBOX
Acoustic
is nominally 8 Ω, with a DC resistance of 5.3 Ω.
Electrically, the amplifier output stage runs differentially, using a 48V rail. The output stage can
source in excess of 41Vp or 28Vrms into the speaker load. This yields the following typical specs:
Maximum Instantaneous Peak Power: 280W.
Musical Peak Power: 236W.
RMS Power: 130W.
Sustained Average Music Power: 200W.
Finally, Two Words About Modding: Please Don’t.
Sooner or later, most of us get the urge to modify or improve our amps by replacing various parts.
But, remember, the LUNCHBOX
Acoustic
is not like other guitar amps. It is a highly integrated and
optimized system, combining electrical, acoustical and mechanical subsystems. Replacing any
element of this combination is sure to upset the balance and operation of the whole. For example,
our speaker driver is fully custom, and built using special high-power components. You won’t find
anything else quite like it. So enjoy your LUNCHBOX
Acoustic
, and please do send us any and all
suggestions you have. We take our customers’ input very seriously. (Oh, and we like compliments,
too!)
Thanks!
