Expert Audio Engineering Commentary

Headroom Notes

A single-channel block rated 200 W into 8 ohms across 20 Hz - 20 kHz at under 0.05 % THD - a full-bandwidth rating, not a 1 kHz one. The 4 ohm figure of 325 W is the looser measurement (1 kHz, under 0.1 %), and both are stored so the difference stays visible.

Thermal Behavior

Emotiva is one of the few makers that states the load limit in words rather than leaving it to be guessed from a power table: 'Minimum Recommended Load Impedance (per channel): 4 Ohms (equals one 4 Ohm load or two paralleled 8 Ohm loads)'. The parenthesis matters - it is the only place in this batch where a manufacturer spells out what happens when two pairs of speakers share one channel.
