Soulution 727

The 727 preamplifier achieves new levels of minimal noise, phase errors, distortion, and common mode noise rejection.

An innovative input stage uses parallelized instrumentation amplifiers featuring wide bandwith and extremely low noise with greater than 105dB of common mode rejection, to ensure the faintest details are received and reproduced. The class-A output stage has been optimized for speed, precision, and high-peak current.

Volume control is performed using relay-switched high-precision metal foil resistors, one network per channel. Balance is adjustable. A secondary IC-based volume control is temporarily used when changing the volume to avoid clicking noises or potentially harmfal volume peaks while switching relays.

An optional phono preamplifier module is available. Faster amplifier stages ensure accurate reproduction of the RIAA equalization curve in both frequency and phase.

Front panel buttons and rotary encoder can be used to control and configure the 727. The LINK (remote turn-on) connection can be connected to other Soulution products.
