DC-2 Digital Controller

System Configuration

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. All summing and filtering is performed in the digital domain. You can select four different crossover points (OFF, 40, 80 or 120Hz) for the subwoofer. Although you can 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-2.

NO mutes the subwoofer output and disables the Subwoofer Level param- eter. For any 5.1 channel input, selecting NO routes the LFE (.1 channel) to any front speaker set to LARGE.

Subwoofer Frequency Response

The low pass filter attenuates high fre- quencies at 24dB per octave. The values given are for the 6dB point.

Selecting THX CONFIG from the SPEAKER SETUP menu automatically sets the speaker selections to the traditional configuration for THX listening. This configuration automatically sets REARS to NONE and all of the filters to 80Hz. This configuration is not adjustable.

Selecting SURROUND EX from the SPEAKER SETUP menu (available only in software Version 4) automatically sets the speaker selections for a THX SURROUND EX setup with two side and two rear speakers, and with all filters set to 80Hz. These settings are not adjustable.

When DC-2 input and output levels are set properly, the entire system will be calibrated to play films at the level intended by the director. Setting the output levels is easy with a Sound Pressure Level (SPL) meter. Using the DC-2Õs internally generated calibration signal, adjust the level of each output to the same relative level (75dB).
