MP-1 CONTROL UNIT
The MP-1’s balanced architecture offers extremely low noise and excellent linearity. Its output stage is designed as a pure Class A amplifier, enabling high bias current while maintaining low crossover distortion. The MP-1 is therefore able to guarantee a wide frequency response and dynamic range for sound reproduction as close as possible to the original audio file.
Signal amplification within MP-1 is essentially achieved by 4 independent transistors. Each channel has two transistors working together to amplify the signal in balanced mode. Even in RCA, the signal is converted to a bipolar signal to suppress common-mode noise and enhance dynamics.
Inside the MP-1 preamplifier are 4 networks of 64 resistors for precise volume control. 32 fully sealed reed relays complete the package. This volume control system minimizes any negative impact on sound quality and ensures excellent coherence between the two channels. The operating noise of the relays is virtually inaudible, for smooth, undisturbed volume control.
Versatile operating modes
One of the advantages of the MP-1 is the ability to independently set attenuation and volume compensation for each input. In addition, the XLR outputs can be operated simultaneously or separately. In the case of separate outputs, each output volume is individually adjusted for best results when using multiple amplifiers and speakers. If you use both XLR outputs simultaneously, you can easily set up a bi-amplification system.
