When using the BAVM-860 SAW with a stereo encoder it may be necessary
to disable the audio pre-emphasis circuit. Refer to your stereo encoder’s
instruction manual for required modulator settings. Should the audio pre-
emphasis need to be disabled, move the jumper according to the diagram
at the right.
AUDIO PRE-EMPHASIS ENABLE DISABLE
NOTE:
Blonder Tongue’s SE Series of stereo encoders do
not require the audio pre-emphasis to be disabled. When it
comes to using the SE Series with a BAVM-860 SAW, keep the
jumper as it comes from the factory in the enable position.
