This is the optimum operating level of the unit, offering the best
performance whilst allowing a large enough buffer to
accommodate the unpredictable nature of music. It is the
reference output level to which other specifications, such as
sensitivity and gain, are referred. The Rated Output does not
indicate the full capability of the SXH2.

Voltage Swing ...................................................................... 31.5V
p-p
Loud transients call for a sudden burst of power from the
amplifier to drive the headphones. This force is voltage. Peak-
to-peak voltage is a more useful specification than Watts when it
comes to delivering power to a speaker.

Maximum Gain ....................................................................... 15.0dB
The amount of amplification the amplifier is asserting on the
input signal. Gain can be calculated by dividing the rated output
by the input sensitivity.
