effect with the factory preset settings. If a DTS signal is coming in, the DC-2 will load the DTS FILM effect with the factory preset settings.

Dolby Digital (AC-3) and DTS encoded sources can produce low frequency peaks that are much louder than those in matrixed Dolby Surround decod- ing. These higher levels may be troublesome in the home listening environ- ment, either because they disturb non-listeners in nearby rooms, or because of the inability of the subwoofer and its associated amplifier to reproduce these levels without clipping.

The DC-2 provides a Subwoofer Peak Limiter that prevents the subwoofer signal level from exceeding a preset value. The limit is factory preset to a level of +15dB. This setting can be changed within the limiterÕs operating range of -5dB to +35dB, with -5dB providing maximum limiting.

To turn off the limiter or to change its setting, select the SUB PK LIMITER parameter in the Output Levels menu.

If you want to turn the limiter off, first turn the system volume down in order to prevent the subwoofer from overloading.

Press ▼ to select LIMITER, then press SELECT. Press ▼ to select OFF. Press DONE twice to return to the Output Levels menu. While readjusting the system volume back to a comfortable listening level, check to be sure the subwoofer or its amplifier is not overloading on passages with loud low frequency peaks.

Selecting LIMITER ADJUST in the Sub Peak Limiter menu invokes a calibration routine for setting the optimal peak level for your installation. Pressing SELECT routes low frequency calibration noise to the subwoofer output of the DC-2. A two-line display indicates the LIMITER LEVEL setting in dB on the top line with a bar at the bottom to indicate relative noise level. Press ▲ and ▼ to adjust the noise level to the highest level that your equipment can reproduce without overload.

Be sure the limiter is set to ON before exiting. Press DONE to exit and

automatically set the limiter to the level you have selected.

Note that the Volume control is ac- tive when utilizing external noise.

Note that +00dB=85dB, and +15dB=100dB in a properly cali- brated system.

Note that the Sub Peak Limiter is separate from the Subwoofer level control in the Effect Adjust menus — one setting does not affect the other.
