EQ/Delay 8
28 DB4 / DB8 MKII Algorithms
Output Level
Range: Off, -120 to 0 dB
For each of the eight Outputs, separate Output
level controls are available.
Delay in milliseconds
Range: 0 to 1000 ms.
For each of the eight channels, a Delay mea-
sured in milliseconds can be added for aligning
purposes. The Delay can be changed seamless-
ly on the fly.
Delay in samples
For each of the eight channels, fine-adjustable
Delay measured in samples can be added.
The Sample Delay is additional to the delay pa-
rameter in milliseconds.
The corresponding value in milliseconds de-
pends whether the DB8/DB4 is running at 44,1 or
48 kHz sample rate. E.g. 48 samples is equal to 1
ms at 48 kHz and 1,088 ms at 44,1 kHz.
EQ page
Introduction
This digital EQ features a four-band parametric
EQ with high- and low-pass filters switchable
between Notch,
Parametric, Shelving and Cut filters. The needle
sharp notch filter has a range down to 0.01 oc-
tave and the shelving filters has a variable slope,
ranging from gentle 3 dB/oct over 6 and 9 to
12 dB/oct. Cut filters are switchable between
12 dB/oct maximum flat amplitude (Butterworth)
or flat group delay (Bessel) types. The paramet-
ric equalizer features a natural and well defined
bandwidth behavior at all gain and width set-
tings:
Basic operation
The available buttons are labeled depending on
the selected Link Mode at the Main page.
– Press keys Lo, Mid1, Mid2 and Hi to activate/
deactivate the EQ bands.
– Select Freq, Gain, Type or Lo/Hi to access all
four parameters on individual bands.
– Press Bypass EQ to bypass all four bands.
Type Selector
Press Type and use faders 1 to 4 to select filter
types.
For Lo and Hi filters select between filter types:
Parametric, Notch, Shelve and Cut.
For Mid 1 and Mid 2 filters select between filter
types: Parametric and Notch.
Parametric Filter – Broad type
Shelving Filter
Notch Filter – Narrow Type
