Front L/R
Select LARGE for full-range front speakers to deliver full frequency
response to the front left and right outputs. Selecting SMALL activates
a 12dB per octave highpass filter and automatically routes low fre-
quency information to the subwoofer output. Choices of 40, 80 and
120 Hz are available for the -3dB point. The SMALL setting is recom-
mended unless your speakers are capable of handling full audio
signals, or are equipped with their own crossovers.
PGM Trigger Assignment
This menu item assigns the status for the programmable (PGM) trigger

selected input. The factory default is ENABLE (high) for A/V inputs and
DISABLE (low) for audio only inputs. (+5VDC is available via internal
jumper. Contact your dealer or Lexicon Customer Service to perform
