Specifications
Explained
Sensitivity..............................................................0.24mV to 7.5mV
The Sensitivity figure indicates the input voltage required to
achieve “rated” output (0.75V
RMS
). This can be adjusted to suit
your cartridge by configuring the Gain setting of your SXV2.
Gain .............................................................................. 40dB to 70dB
The amount of amplification the preamplifier is asserting on the
input signal. Gain can be calculated by dividing the rated output
by the input sensitivity. User configurable via the external DIP
switches.
Input Impedance.........................................................10Ω to 47kΩ
The resistance “load” that is presented to the source component
that is driving it. The Input Impedance can be set using the
external DIP switches to meet the requirements of your cartridge.
Input Capacitance .................................................. 27pF to 417pF
The capacitive “load” that is presented to the source component
that is driving it. The Input Capacitance can be set using the
external DIP switches to meet the requirements of your cartridge.
THD+N ........................................... 0.002%, 1kHz @ rated output
Total Harmonic Distortion + Noise is the percentage of output
signal which is made up of frequencies added due to harmonics
of the fundamental frequency and noise. By using low-noise
input circuitry and high-precision amplification stages, Perreaux
engineers have kept this figure to a minimum.
Signal to Noise Ratio .......................................85dB, unweighted
The ratio of desired signal to noise signals in the output. Phono
reproduction is inherently susceptible to noise because of the
extremely low output voltage of the cartridge (100’s of µV in the
case of Moving Coil). This is why Perreaux engineers have
designed the SXV2 to maintain a low noise floor.
Input Overload Margin ............................................................20dB
The amount of headroom available over and above the Rated
Output.
