Input Channel GEQ (Graphic Equalizer)

Use the < Select > buttons to make the top line of the Edit screen active and the Value Up and Down buttons to navigate to the Input GEQ screen.

GEQ

UT

The DC-One’s input signal path includes a stereo 31-band graphic equalizer after the stereo 9-band PEQ in the signal path. This DSP block can be used for very precisely identifying, isolating and correcting problematic frequency ranges.

Keep in mind that changes to the Input GEQ will be interactive with adjustments made in the Input PEQ. Unexpected results can occur.

Press the < Select > buttons to move the cursor down into the GEQ frequency adjustment field. Subsequent presses of the < Select > buttons will move the cursor forward or backwards through the frequency adjustment field; from band to band. The selected frequency’s “fader” is

highlighted in the display. As each band is selected, its center frequency and current cut/boost setting is displayed on the top line of the LCD display.

To adjust the amount of boost or cut for a selected frequency band, select the band with the < Select > buttons and press the Value Up or Down buttons as required. The LCD display will reflect your changes by moving the selected frequency band’s “fader” up or down.

To exit the Input GEQ edit screen, press the Input GEQ button, use the < Select > buttons to again highlight the top line of the edit screen display or press any other DSP block button.

Input Delay

DC-One offers an input delay that is useful for compensating for different arrival times of sound originating from loudspeakers that are closer or further away from the listener than others. A technique known as the Haas Effect allows the operator to create the illusion that all of the sound has originated from the stage even though additional speakers have been placed around the room.

Available Input Delay parameters are Delay, Units and Bypass. The Delay parameter allows the user to determine the Delay time values (-200.00ms to +700.00ms.) and the Bypass parameter simply toggles between On/ Off.

To access the Input Delay, press the Delay button found on the input processing menu. Subsequent button presses will toggle the display between Input A and Input B. Input delay parameters are accessed using the <SELECT> button to navigate between Delay and Bypass using the VALUE up/down keys to adjust values.

Example - Input B Delay is set to 75 feet. In this illustration, speaker ar- ray B is said to be 75 feet in front of Main speaker array A. The effect of air temperature is also automatically calculated for the total delay time using the Temperature value en- tered in the Setup Menu.
