soulution’s new reference preamplifier sets new benchmarks in terms of noise, phase errors, common mode rejection and distortion.

Input stage

The innovative input stage of the727 preamplifier enables exceptional common mode rejection without compromising the input stage by introducing noise. This is achieved with parallelized instrumentation amplifiers designed for wide bandwidth (20MHz), lowest noise (noise density < -160dBV/√Hz) and optimal common mode rejection (CMMR >105dB). This ensures that even the faintest musical signals can be properly received by the 727 preamplifier.
