Portable Instrument Amplifier Figure 74 details possible connections for a portable setup for an electric bass. Ideal for this application, the P-2200 can easily reproduce the high power bass notes that may be clipped off by lower power instrument amplifiers. Thus, it will "clean up" a bass sound, and, because clipping is dangerous to speaker systems, the P-2200's high power output may be easier on a speaker system than a low power amplifier. In addition, the P-2200 is sensitive enough (and its input is high impedance) that it can be driven by the output of many hi-fi or semi-pro type preamps. Its peak reading meters help the musician avoid overdriving a speaker system, and the calibrated attenuators allow the instrument amplifier system to be turned down during a "break" without modifying any of the preamp settings. All of these advantages hold true when the P-2200 is used as a keyboard amplifier, with the additional advantage of true stereo operation. Fig. 74 - Instrument Amplifier

Portable Instrument Amplifier
Figure 74 details possible connections for a portable
setup for an electric bass. Ideal for this application, the
P-2200 can easily reproduce the high power bass notes
that may be clipped off by lower power instrument
amplifiers.
Thus,
it
will
"clean
up"
a bass
sound,
and,
because clipping is dangerous to speaker systems, the
P-2200's high power output may be easier on a speaker
system than a low power amplifier. In addition, the
P-2200 is sensitive enough (and its input is high
impedance) that it can be driven by the output of many
hi-fi or semi-pro type preamps. Its peak reading meters
help the musician avoid overdriving a speaker system,
and the calibrated attenuators allow the instrument
amplifier system to be turned down during a "break"
without modifying any of the preamp settings.
All of these advantages hold true when the P-2200 is
used as a keyboard amplifier, with the additional
advantage of true stereo operation.
