The current preset memory location and name are displayed as well as the configuration on which the preset is based. Caution Before operating the sound reinforcement system, and any time a new preset is recalled, check the configuration display to make sure that it is appropriate for your system and that connections to your system are correct for the current configuration. Failure to do so could cause unexpected results or damage to the system or its components. The LCD display's contrast can be adjusted in the Setup Menu to accommodate different viewing angles. Input Level Meters During operation, the left and right input level meters display the signal present at the DC-One's analog and Digital inputs. The DCOne does not itself have input level controls. Proper input level setting is accomplished by setting the output level from the (L / R) bus outputs from the connected mixer or other audio source. Optimal signal-to-noise performance is obtained when the nominal (average), input level consistently lights the +3dBu (green) and / or +6dBu (yellow) LED indicators. As the DC-One is a digital audio device ­ and digital clipping produces very unpleasant results ­ the Clip (red) LED should never light. If it does, reduce the output level of the connected mixer. Output Level Meters Each output channel has an eight-segment output level VU meter. Meter response characteristics can be selected in the Setup menu: Normal Fast, Peak-Hold or Slow Decay. The yellow segment indicates that limiting is being applied to the output channel. If the preset you are recalling is based on a configuration different from that of the current preset, the display will prompt, "Changing config can damage speakers", to remind you that the new preset may not be appropriate for your system as it is currently connected. Press Recall again to confirm and load the new preset. Owners Manual 21 Make sure that the new preset is appropriate for your system, and that connections to your system are correct for the current configuration. Failure to do so could cause unexpected results or damage to the system or its components. To exit the Recall process without loading a new preset, press the Edit, Setup or any of the DSP block buttons. (Edit or Setup buttons will return the display to run-time mode. DSP block buttons will display the corresponding DSP block edit screen. ) Preset Store Edited presets can be stored in one Store of 20 User Preset locations. (U01 ­ U20) To store a preset, press the Store button. The LCD display will switch to the Store Program screen. Use the Value Up and Down buttons to select the user preset location you wish to designate as the destination. Locations that already have presets saved in them will display a preset name.
