Speaker Configuration - Lexicon DC-2 Owner's Manual

DC-2 Digital Controller
This menu item assigns the status for the programmable (PGM) trigger on
the DC-2 rear panel. +12VDC is provided for controlling ancillary equip-
ment 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.)
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 three selections are for CUSTOM,
THX or SURROUND EX configuration.

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.
