Soulution 325

The 325 preamplifier features an unbalanced design for minimal components in the signal path. Left and right channels are physically isolated for optimal channel separation.

Volume control is performed using relay-switched metal foil resistors. A secondary PGA-based volume control is temporarily used when changing the volume to avoid clicking noises or potentially harmfal volume peaks while switching relays.

A switched mode power supply with audiophile converters and regulators provide stable and low-noise power to the 325. The power supply is physically separated from the analog audio circuitry, and additional shielding is utilized.

Home theater bypass is supported. Optional phono and DAC modules are available.

Front panel buttons and rotary encoder can be used to control and configure the 525. The LINK (remote turn-on) connection can be connected to other Soulution products.
