Jumpers
The board jumper switches are CD_MUTE channels 1 and 2 and EQ_BYPASS channels 1
and 2. In the factory default board configuration, jumpers are installed on the
CD_MUTE
jumper switches (J4 and J6) and not installed on the EQ_BYPASS jumper
switches (J5 and J7). When jumpers are not installed on J5 and J7, the EQ_BYPASS
signal can be controlled from the host device.
Table 2–11 lists the jumper descriptions and schematic signal names.
