Speaker Configuration - Lexicon DC-1 V3 Owner's Manual

DC-1 Version 3 Digital Controller
This menu item assigns the status for the programmable trigger (PWR CTL)
on the DC-1 rear panel. +12VDC is provided for controlling ancillary
equipment or functions. Selections are ENABLE or DISABLE for the se-
lected 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.)
The Speaker Configuration menu allows a wide range of choices in speaker
type and room setups to provide optimal performance in almost any room.
An adjustable lowpass filter is available for the subwoofer, as well as a
highpass filter for all other speakers. The two selections are for CUSTOM or
THX configuration.
Press SELECT to open the CUSTOM CONFIG menu. Press SELECT to
access the selections for any highlighted menu item.
Select LARGE for full-range front speakers to deliver full frequency re-
sponse to the front left and right outputs. Selecting SMALL activates a 12dB
per octave highpass filter and automatically routes low frequency informa-
tion to the subwoofer output. Choices of 40, 80 and 120 Hz are available for
the -3dB point. The SMALL setting is recommended unless your speakers
are capable of handling full audio signals, or are equipped with their own
crossovers.
