4. External analog circuit
Figure 9 shows an input buffer circuit example 1. (1
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 +/−12.7Vpp (AK5394A: +/−2.4Vpp Typ.). When using this circuit,
analog characteristics at fs=48kHz is DR=120dB, S/(N+D)=105dB.
