All amplifiers are FCC class B (conducted and radiated emissions), UL/CE listed
1) Free Field Response (4pi)
2) Calculated based on sensitivity and continuous amplifier power at onset of limiting
3) Calculated based on sensitivity of transducers and peak output capability of amplifier
4) Coverage: Included angle between -6 dB points, 500 to 3.2k Hz, taken at ISO preferred one-third octave intervals, or for an otherwise specified frequency range
5) Amplifier Power: The maximum sustained power at less than 1% clipping, averaged over the intended frequency range
6) Current values are for 120V, for 230V operation divide by 2
