Frequency Response.............................. 20Hz to 20kHz, ±0.1dB
This describes how the SXD2’s output level responds to
frequency. Indicating that the SXD2 responds to all frequencies
from 20Hz to 20kHz with no more than 0.1dB deviation in the
amplitude or strength of the output signal. This also gives you an
idea of the bandwidth of the SXD2.
Signal to Noise Ratio (A-W eighted ) ........................................ 113dB
The ratio of desired signal to noise signals present in the output.
It is important in line-level components to design the circuit to
keep this value at a maximum. Line-level components typically
occur early in the signal chain; hence any noise introduced will
be amplified. This is why Perreaux engineers have designed the
SXD2 to maintain a low noise floor.
Crosstalk.................................................................................... -113dB
This is the level of undesired capacitive, inductive, or conductive
coupling from one channel to the other. Meticulous PCB and
ground plane design has ensured that crosstalk is very low.
