Specifications
Explained
THD+N .................................................................... 0.001%, @ 1kHZ
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.
Frequency Response..................20Hz to 20kHz, +0dB -0.05dB
Shows that the amplitude or strength of the output signal deviates
by no more than 0.05dB over the entire audio band.
Signal to Noise Ratio ( unweighted ) ........................................ 118dB
The ratio of desired signal to noise signals in the output.
Perreaux engineers have designed the SXP2 to maintain a low
noise floor.
Crosstalk.................................................................... -120dB @ 1kHz
Crosstalk is caused by stray inductances and capacitances
between components and lines, which results in unintentional
mixing of stereo signals. Meticulous wire routing ensures
excellent high-frequency separation.
Channel Tracking................................................................... 0.50dB
Channel tracking is the difference in level between the left and
right channels. It is worst at the extremities of the potentiometers
rotation.
Gain Range ...................................................................-93dB to 0dB
The range in which the SXP2 can alter the volume level. At the
minimum setting the volume level is -93dB, at the maximum
setting the level is 0dB.
Input Impedance....................................................................... 10kΩ
The resistance “load” that is presented to the source component
that is driving the SXP2.
Potentiometer Type.........................................................Audio Log
Potentiometers are available in a range of configurations and fall
into two major categories, linear and logarithmic. Audio taper
potentiometers are logarithmic and are widely used in audio
because the human ear responds on a logarithmic scale.
