12) To allow the module SE/BTL control input to switch the amplifier IC
between single ended (SE) and bridge-tied load (BTL) output modes, set
output mode jumper SE/BTL to
OFF. To keep the module amplifier IC in
the single-ended output mode regardless of the control input state, set
jumper SE/BTL to
ON.
13) To allow the module HP/LINE control input to switch the amplifier IC
between the HP pins and the LINE pins as the signal inputs, set the input
mode jumper HP/LINE to
OFF. To keep the amplifier IC in the HP input
mode regardless of the control input state, set jumper HP/LINE to ON.
14) To allow the amplifier IC to switch from the LINE inputs to the HP inputs
when the output switches from BTL output mode to SE output mode and
vice versa, set jumper HP–SE to
ON. To allow the inputs and output modes
to switch independently, set jumper HP–SE to
OFF.
15) To enable bass boost, set BBENABLE to
ON. To disable bass boost, set
BBENABLE to OFF.
16) To select the onboard active or passive filter, set the FILTER SELECT
jumper to
ACT for the active filter or to PAS for the passive filter.
