About the MPS-1
The Emotiva MPS-1 is a high-performance seven-channel power amplifier featuring a class H design that modulates the power supply rail voltage to improve efficiency and reduce heat. It delivers 200 watts per channel into 8 ohms, 300 watts into 4 ohms, and 400 watts into 2 ohms. The amplifier uses four high-current complementary output BJTs per channel to ensure low output impedance and stable frequency response with reactive speaker loads. It includes large power supply capacitance arranged in a series-parallel configuration to provide high voltage and sufficient headroom. Each amplifier module is powered by a dedicated 350VA toroidal transformer, enhancing channel-to-channel crosstalk rejection and power delivery. The MPS-1 supports balanced XLR and unbalanced RCA inputs, has a frequency response of 20Hz to 20kHz ±0.1 dB, signal-to-noise ratio of 100 dB unweighted, and crosstalk greater than 120 dB. It weighs approximately 115 lbs and measures 7 11/16" x 18 7/16" x 18 13/16" (HxWxD). The amplifier is fully protected against fault conditions and uses fan-assisted cooling for quiet operation.
