Installation and

Calibration

This menu sets the system for your particular side speaker configuration.

Systems with side speakers should be designated as STANDARD (LARGE

or SMALL) or DIPOLE (LARGE or SMALL). DIPOLE indicates a THX

speaker configuration, and causes the unit to mute the rear outputs when

either THX effect is used. When STANDARD SMALL or DIPOLE SMALL

is highlighted, press SELECT to display and adjust the highpass filter for the

side outputs. Choices are: OFF, 80, 100 or 120Hz.

Selecting NONE mutes the side outputs and disables any effect parameters

related to side speakers.

In the Dolby Digital version of the DC-1, the active selections are LARGE

and SMALL. Systems that utilize full-range rear speakers should select

LARGE to direct a full-range signal to them. SMALL should be selected

when filtering is desired. (Off, 80, 100 and 120Hz are available as settings for

the -3dB point).

Selecting NONE mutes the rear outputs and disables any effect parameters

related to rear speakers.

Use of the subwoofer output is specified here. Selecting YES, then pressing

SELECT allows you to display and adjust the crossover frequency for the

subwoofer output. The subwoofer output is created by summing the front,

left, center and right outputs, followed by a 24dB/octave lowpass filter. For

5.1 effects in the Dolby Digital version, the two surround channels and the

LFE channel are also summed. Both the summing and filtering are per-

formed in the digital domain. You can select three different crossover points

(80, 100 or 120Hz) for the subwoofer. Although you can also elect to bypass

the crossover and run a full range output if your subwoofer has an internal

crossover, it is generally best to use the crossover in the DC-1.

NO mutes the subwoofer output and disables the Subwoofer Level param-

eter.
