Note:
Utilising a stable current source, along with accurate current mirroring circuitry, the input stage of the SXH2, in combination with the overall circuit topology, provides precise detail resolution and definitive sonic transparency.
Special attention has been lavished on the PCB layout. The unit is symmetrical in design with each channel being isolated from the other. The super clean custom designed power supply is physically segregated from the rest of the sensitive electronics.
Special attention has been paid to ground planes to maintain sonic purity. All signal grounding is optimised to provide a platform for a black background and increased dynamic range.
Two gain settings are available, enabling optimum performance and listening levels to be achieved from both high and low impedance headphones.
The output stage is capable of delivering 1.0WRMS per channel into a 64Ω load and is stable down to 4Ω, enabling the SXH2 to effortlessly drive a vast array of headphones with the control and authority that people have come to expect from Perreaux products.
Two stereo headphone jacks give the option of connecting two sets of headphones, allowing another party to be enveloped by the detailed and dynamic musicality of the SXH2.
Please ensure that the resulting impedance of the two headphone sets is not below 8Ω. Use the following equation to calculate the total impedance: RT = (R1 * R2) / (R1 + R2).
