Channel Level (Output Channels)
The Channel Level is used to adjust master
output levels. To access the Channel Level
screen, press the Level button found on
the output processing menu. Subsequent
button presses will toggle the display
between OUT1 to OUT6. Use the
<SELECT> button to navigate between the
selectable Level parameters (-100.0dB to
+6.0dB). Adjust the value by using the up/down VALUE arrows.
Channel Limiter (Output Channels)
DC-One’s output channel limiters prevent
audio signals from exceeding a set level.
Press the Level button to change the
output channel. Hold-down the Level
button for 4 seconds - you will then be
presented with
the Limiter
screen. Use the
< SELECT>
key to navigate
between
Threshold (-9.0
dBu to + 21.0
dBu), Release
(50.0ms to
300.0 ms), Amp
(preset values for specific power amplifiers) and
Bypass (on/off). Adjust the values of each
parameter using the up/down VALUE arrows.

Limiter threshold values are determined by the amplifiers
and loudspeakers that are used in the system. One
important consideration in setting the limiter threshold value
is the input sensitivity and gain of the connected amplifiers.
Because different amplifiers can have different sensitivities,
it is common to need to calculate the limiter offset to a
factory preset based on the amplifier sensitivity. The DC-One
offers a unique solution to this problem with the Amp
parameter. All EV Factory Presets include limiter threshold
values. You may use the Amp parameter to select the model
of EV amplifier that you are using and the limiter threshold
offset will be automatically calculated based on the amplifier
gain and sensitivity. When an amplifier is selected from the
list, the actual Threshold parameter will be locked to ensure
that proper settings are maintained. It is very important to
ensure that the proper amplifier is selected from the list, as
an improper selection can result in incorrect Limiter settings
for your system and may result in system damage. If a non-
EV amplifier is used in the system, selecting “Other” from
the amp list will allow the Threshold setting to be directly
edited, however, the amplifier documentation should be
consulted so you can calculate you limiter offset (if any) as
needed. The Amp parameter is only available when using a
Factory Preset.
