Perreaux SXV2 ユーザーズマニュアル

Gain With a gain range of +40dB to +70dB, the SXV2 is incredibly
sensitive. Working in combination with the wide selection of R
and C loading the user has no need for messy MM/MC jumpers
as any type of cartridge can be matched via the external
selectable DIP switch settings.

RIAA
Equalisation
The RIAA equalisation utilises a robust architecture with high
precision, low noise resistors and highly linear, metalised
polyester capacitors for optimum signal transfer. Deviation from
the RIAA specification is only ±0.5dB across the audio-band.

With both Normal and IEC RIAA equalisation curves to choose
from, you can be guaranteed you’re getting the optimum from
your valued record collection.

Low Noise
Input Stages
Low-output Moving Coil cartridges present very different source
characteristics to the phono preamplifier than high-output
Moving Coil or Moving Magnet cartridges.

Moving Coil or Moving Magnet cartridges.
The SXV2 incorporates two separate, low noise, input stages
selectable via external DIP switches. One tailored to specifically
satisfy the requirements of interfacing to low-output MC
cartridges, the other to high-output MC/MM cartridges.

PCB Layout Special attention has been lavished on the PCB layout. The unit
is symmetrical in design (note the DIP switch numbers, they are
a mirror of each other, and the input/output RCA configuration),
with each channel being isolated from the other. The low noise,
custom designed, power supply is physically segregated from the
rest of the sensitive electronics.

Earth
Isolation
Special attention has been paid to ground planes to maintain
sonic purity. All signal grounding is isolated from mains earth.
