5.0 DESCRIPTION OF MAIN FUNCTIONS
ADJUSTING INDIVIDUAL FREQUENCIES:
• Press one of the frequency buttons below the screen. A cursor is shown at
the bottom of the selected fader and its GAIN and FREQUENCY values are
displayed at the top of the screen.
• Adjust the gain of the selected frequency with the DATA WHEEL.
Alternatively select the required frequency with the DATA WHEEL in
Parameter mode. Note that after 20kHz the cursor goes to the GAIN fader.
ADJUSTING A BAND OF FREQUENCIES:
• Press and hold two of the frequency select buttons. Two cursors are shown
indicating each end of the selected band. These frequencies are also shown
at the top of the display. Any cut or boost adjustment affects all frequencies
within the band selected.
GAIN:
GAIN controls the level of signal into the graphic equaliser. It can be used to
reduce overall gain where large boost levels are being used. It can also be used
to set different gains for Channels A & B, which can then be linked for overall
adjustment (see LINKING WITH OFFSET).
BYPASS:
BYPASS acts on the selected channel or channels and has the effect of returning
all faders to their 0dB (flat) positions.
5.2 PARAMETRIC & FILTERS
PARAMETRIC
The parametric equaliser on the DPF3103 has 3 fully variable (frequency, gain and
bandwidth) bands. Each band has -40dB cut and +15dB boost, 20Hz to 20kHz
frequency range and 1/32 to 2 octave bandwidth adjustment. The large cut range and
narrow bandwidth available make the equaliser ideal for notching out feedback.
The High pass (low cut) filter is adjustable between 16Hz & 630Hz and the Low pass
(high cut) between 656Hz and 20kHz. Both have selectable slopes of -12dB/octave
Bessel or Butterworth and -24dB/ octave Linkwitz-Riley. There is also an OFF
position.
• Press PARAMETRIC & FILTERS button once to select the Parametric
equaliser and Filters page.
• Press PARAMETRIC & FILTERS a second time to select the Shelving
equaliser page.
• Press PARAMETRIC & FILTERS again to return to Parametric & Filters page.
