About the MPS-1
The Emotiva MPS-1 is a modular seven-channel power amplifier built around individual monoblock amplifier modules in a card-cage chassis, each with its own dedicated power supply for maximum channel separation. It is rated at 200 watts per channel into 8 ohms, 300 watts into 4 ohms, and 400 watts into 2 ohms with all seven channels driven. The amplifier delivers a frequency response of 20Hz to 20kHz ±0.1 dB, a signal-to-noise ratio of 100 dB (unweighted), and crosstalk greater than 120 dB, ensuring excellent channel isolation for demanding multichannel systems. Both balanced XLR and unbalanced RCA inputs are provided on each channel for flexible integration with home theater processors. The modular design allows the chassis to be configured from fewer channels up to the full seven-channel complement using individual mono modules. It weighs approximately 115 lbs and measures 7 11/16" x 18 7/16" x 18 13/16" (HxWxD).
