Crosstalk on the same channel
The output to the matrix is being heard on the same channel’s input. The input to the Codec need to be AC coupled. To fix the
crosstalk on the same channel, you must remove 16 resistors (150Ohm) - R12, R14, R17, R18, R324 - R327, R355 - R358,
R402 - R405 and replace with 16 capacitors (part number 102881-880, 0.47 uF 16V) in R12, R14, R17, R18, R324 - R327,
R355 - R358, R402 - R405. For replacement positions, see figure 1.
