DIFFERENTIAL MONO INPUT
w
Table 30 PCBEEP Control
PCBEEP and MONOIN inputs can be configured to provide a differential mono input. This is
achieved by mixing the two inputs together using the headphone mixers or the speaker mixer. Note
that the gain of the MONOIN PGA must match the gain of the PCBEEP mixer input to achieve a
balanced differential mono input.
