3. Polarity-function
The polarity of every output can be inverted. If the polarity of a linked output will be inverted, the
polarity of the other channel will also be inverted.
4. Delay
With the delay, it is possible to compensate differences in the running distances between different
speaker-systems or speaker-systems at different installation spots.
The delay can be adjusted for both inputs and all outputs between 0 and 7 ms in 0.5 ms steps.
How to calculate the delay-time:
The delay-time T equals the distance in meters (D) divided by the speed of sound (C).
T=D/C
How to calculate the speed of sound: C=20.6 * (273 + °C) in meter per second.
5. Hi-pass/Lo-pass
Hi-pass filter for passing higher frequencies.
Lo-pass filter for passing lower frequencies.
If several parameters are displayed, you can switch from parameter to parameter by pressing the
Parameter (15) knob.
The active parameter is marked with a hook.
Adjust the crossover frequency and the filter type via the Parameter knob.
6. Equalizer
There are five parametric equalizers per output.
The individual equalizer band can be deactivated by pressing the
Enter (4) button (Bypass). The
symbol in the upper right corner of the display changes to =.
If the equalizer is activated, you can adjust the frequency (20 Hz to 20 kHz), the Q-factor (0.5 to 10)
and the gain (± 12 dB, ± 1 dB).
By pressing the
Parameter (17) knob, you can jump to the next parameter.
Additionally, you can switch the equalizers to shelving characteristic. Set the gain to 0 dB.
If you select a Q-factor below 0, you can choose between Hi-shelf and Lo-shelf.
7. Limiter
The DCX-36 MKII features a limiter-function with independent limiters (one per output).
The limiter serves as an additional clipping protection to avoid speaker damage. The signal level is
always limited to the adjusted threshold-level.
In most cases, it is sufficient to adjust the threshold-value to the clipping level of the connected
amplifier. Nevertheless make sure that the amplifier does not distort.
Via the
Parameter (17) knob, you can adjust the limiter between -20 and + 15 dB.
If the limiter will be adjusted to e.g. +2,0 dB the output signal level Limit corresponds to +2 dB and the
levels -2, -6, -12 and -20 dB correspond -1, -4, -8 and -12 dB.
Attack
You can adjust the Attack-time between 1 and 100 ms.
Hold
You can adjust the Hold-time between 0 and 100 ms.
Decay
You can adjust the Decay-time between 10 and 1000 ms.
8. Name
Via the Parameter (17) knob, you can select the best suitable name from a preset name list.
9. Source
Via the Parameter (17) knob, you can check the input sources Input A, Input B or Input A+B but not
change it.
