Configuration

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

on the MC-1 rear panel. +12VDC is provided for controlling ancillary

equipment or functions. Selections are ENABLE or DISABLE for the

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

this change.)
