The innovative input stage of the 727 preamp provides exceptional common-mode signal suppression without compromising the input stage due to noise. This is achieved using parallel instrument amplifiers designed for a wide bandwidth (20 MHz), the lowest noise level (noise density < -160 dBV/√Hz) and optimal common-mode signal suppression (CMMR >105 dB). This ensures that even the weakest musical signals are correctly received by the 727 preamp.

    Soulution Audio 326 preamplifier

    The device operates in the frequency range from 0 Hz to 2 MHz. Speaking of switching capabilities, the amplifier is equipped with a pair of balanced XLR inputs, a pair of unbalanced RCA, one balanced XLR output and one unbalanced RCA.

  • 525 preamplifier

    Preamplifiers

    Soulution Audio 525 preamplifier

    The Soulution 525 preamp owes much to the design of the top-end Soulution 725 preamp. It uses the same volume control, which ingeniously combines the smooth fingertip control of variable resistors with the precision and stability of fixed-resistor circuits.
