Power Rating Note: ‘Peak’ vs. ‘Continuous’
Many companies will rate an amplifier with only one or two channels driven under load, which results in reporting inflated
power output.. In real life, this will drop significantly when all channels are driven. This is called ‘peak’ power conditions
(Peak Music Power Output, or PMPO). ‘Peak power’ represents the maximum amount of power that an amplifier/receiver
can deliver without being damaged. Ratings are performed this way for the sole reason of exaggerating the perceived power
of the product, and during normal use, the actual practical power output is much lower than the claimed ‘peak’ rating.
Sometimes these ratings are also performed at 10% THD, even thought the industry accepted level is 1.0% THD. This practice
has led many people to seek higher and higher levels of power in amplifiers because they misunderstand the difference
between ‘peak’ and ‘continuous’ power.
All Emotiva amplifiers are rated for continuous power, tested with all channels driven simultaneously. We at do not play
games with the specifications, and test all of our amplifiers to industry standard test conditions with the amplifier put under
the strictest loads. This means that the power output and other specifications listed are the bare minimum (or worst case
scenario) you will receive from our amplifiers. Under normal circumstances you will get much higher output then what is
rated.
The bottom line is this: These amplifiers are powerful, and can give you control over your sound in ways a receiver could
never come close to. We’re proud to offer amazing performance to match the amazing value of the Ultra Series amplifiers.
