11. Recommended Amplifier Performance for the ACCESS System
An audio system is expected to transmit dynamic signals and peaks without distortion.
This needs to be considered when determining if a power amplifier is adequate for a
speaker system. Possible peak power levels of an amplifier are more relevant in this
consideration than the RMS power (continuous power output, root mean square value)
generally provided by the manufacture.
Unfortunately, an amplifier’s RMS power is no indication for its specific peak power. The
difference between peak and RMS power is, however, generally lower with operations
with high impedance load than with low impedance operations.
Because of this, we also specify a recommended peak power (10ms/1kHz) in addition to
the usual RMS power recommendation. This peak power can be calculated or provided
by the manufacturer of the respective equipment.
