4. External Analog Circuit Examples
Figure 23
The analog signal is able to input through XLR or BNC connectors. (short JP1 and JP2 for BNC input, open JP1 and JP2
for XLR input). The input level of this circuit is +/-15.0Vpp (AK5388: +/-2.8Vpp Typ.). When using this circuit, analog
characteristics at fs=48kHz is DR=120dB, S/(N+D)=110dB.
