Audio Power
The following graphs demonstrate typical performance characteristics for the Evacs 1-16.
The test panel was configured in standalone mode and audio output was set as a 1 KHz sine wave with each speaker
output played into a 575Ω impedance load (1230Ω resistive, 110nF capacitive).
Test measurements are intended as a guide only as actual power throughput will differ depending on the audio
played, and may push the system beyond its recommended operating parameters.
Volume controls
Please note that maximum output of the unit is indicative only and that setting the unit beyond the maximum
recommended ratings may degrade audio performance. Actual output power will vary depending on the speaker
system installed.
