The Silhouette Series SXP2 is a compact and stylish passive preamplifier (passive attenuator) and input selector. An entirely passive device, the SXP2 contains no power supply or electronics to affect the audio signal. Ensuring noise levels remain at an absolute minimum and no sonic signature is imposed on the audio signal by the SXP2. This results in quiet, detailed, and dynamic reproduction of any audio signal. As with all Perreaux products, the SXP2 features the finest audiophile grade components throughout. The styling of the SXP2 is subtle and discreet, allowing seamless integration into existing hi fi audio systems or the perfect compliment to other products from the Perreaux range.
