Gain; Protection Circuits - Innosonix MAXX Series User Manual

• Power 16 Ohm → 68W RMS (1% THD+N), 140W Peak 8 Ohm → 130W RMS (1%
THD+N), 280W Peak 4 Ohm → 270W RMS (1% THD+N), 530W Peak
POWER DISTRIBUTION
• The power supply can deliver 2000W continuous power. To ensure a
stable operation in overload situations, the MA32 involves an overall
power limiter. With an attack time of 100ms and a release of 3s the
limiter softly reduces the gain of all channels simultaneously not to
exceed the maximum available power. At 110V lines, a derating of 20%
must be considered.
• The pulse power of 32*530W is buffered through 65.000uF of

capacitors and is certainly available as a short burst only.
• An amplifier efficency of 85% can be expected.
• All amplifiers are sourced by one powersupply.
• Assuming a evenly distribution of load between all channels. The
MA32/D is able to give 50W continous sine power per channel. At 110V
line it is after all 40W.
• Maximum continuous power output per channel is limited to 200W at 4
Ohms because of thermal reasons. (Continous power longer than 10
seconds). There is no limitation at 8 Ohm loads.
