*1) The amplifier's PSU operates as a non-resistive load, so the calculation "Volts x Amps = Watts" would not be correct. Instead, measured and specified here
is what is known as the "Active Power" in the amplifier providing useful, real-world values of power consumption and heat dissipation.
*2) Current draw figures measured at 230 V. as well as 120 V. The efficiency is similar, but not identical for the two scenarios. The efficiency for 100 V mains is
very similar to that of 120 V.

14.3. Asymmetric loading data

Pages 21-23 following list possible settings and load combinations for asymmetric loading. For an explanation of
asymmetric loading, please see Section 13.4.3.
For values followed by an asterisk (*), use of an external limiter may be required for optimum performance.
All values assume amplifier is being driven by a signal from a professional mixing console or DSP unit. Values
will differ if driven by a consumer device, such as an iPod, with significantly lower output (2.71 dBu instead of the
required 4 dBu).
