Control Function Options Notes

PBTL Sets the amplifier in mono PBTL Insert jumper to defeat PBTL mode If PBTL jumper is removed (PBTL

mode when removed and run in normal stereo BTL mode mode), the left outputs (OUTPL and

OUTNL) as well as the right outputs

(OUTPR and OUTNR) are

synchronized and in phase. This

allows them to be connected

together before the reconstruction

filter for PBTL operation.

JP4 Sets switching frequency to 400kHz. Remove jumper to set switching

frequency to 300kHz.
