preserving each filter’s settings. The two Crossover Filters remain
unaffected.
• Reset Parametric EQ Resets all eight Filter parameters to their factory default
settings. The two Crossover Filters remain unaffected.
Crossovers
Description
Each of the eight DX1208 Output Channels is additionally equipped with a pair of Low- and
High-Pass Crossover Filters that occur between the Output Filters and the Limiter in the
DX1208 signal chain. Each Crossover Filter can be set to any of three standard crossover
filter types – Butterworth, Bessel, and Linkwitz-Riley – and adjustable slopes of 6, 12, 18, or 24
dB/octave.
Parameters
• Selected Determines which Filter the Type, Frequency, Gain, and BW/Q,
and Bypass Filter settings apply to. When a Crossover Filter is
Selected, the Gain and Bandwith controls are disabled.
• Type When a Crossover Filter is Selected, Type sets the Filter type
from amongst the following choices: [6 dB], [12 dB Butterworth],
[12 dB Bessel], [12 dB Linkwitz-Riley], [18 dB Butterworth], [18 dB
Bessel], [24 dB Butterworth], [24 dB Bessel], [24 dB Linkwitz-
Riley].
Note: The [6 dB Butterworth] and [6 dB Bessel] filter responses
are identical. Therefore only a single 6 dB filter type is presented.
• Frequency Sets the Frequency center of the Selected Filter. Frequency
values range from [20 Hz] to [20 kHz].
• Bypass Filter Bypasses the Selected Crossover Filter band without changing
any of the Filter’s settings.
• Gain Disabled when a Crossover Filter is Selected.
• Bandwidth / Q Disabled when a Crossover Filter is Selected.
EQ Graph
The response of the Crossover Filters is plotted along with the response curves of the eight
Output Channel Filters. A general description of the EQ Graph and how to edit EQ
parameters graphically can be found in the Input EQ
section of this helpfile.
