3. Bypass Mode Characteristics (L, R channels only)
These are the characteristics without passing through the DSP, and including the prefilter with built-in
operational amplifier and the built-in post filter. Use the analog I/O circuits in the Application Circuit for the
measurement circuit. Unless otherwise specified, the measurement conditions are as given below.
