Monster Power Signature MPA 5150 Owner's Manual page 10

Measuring actual wattage in real time is a complex task – the meters have to measure voltage and current
simultaneously in a circuit with constantly changing impedance. The meters also have to be readable, which is why the
Head Monster designed them to be peak reading meters so power could be easily read without sluggish performance.
The output display can be turned off if you like, and turned back on to show-off to friends.
SEPARATE POWER SUPPLIES FOR THE FRONT AND REAR CHANNELS
A unique feature of the MPA 5150 is that the front and rear channels each have their own transformer and power
supply. Receivers that share a single, ordinary power supply for all channels will actually deliver far lower power levels
under heavy demand. Monster amplifiers do not sag when the power demands are high because they are designed
to support the high current loads required of today's music and movie sound effects. The MPA 5150 delivers detail,
clarity, dimensionality and low distortion audio with powerful bass at virtually any power level.
The MPA 5150 delivers 250 continuous watts per channel into 4 ohms with all channels driven (150 watts/channel
into 8 ohms). Instantaneous peak power exceeds 500 watts into 4 ohms (300 watts/channel into 8 ohms).
