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)
DSP 260'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

Input Level
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
DSP 260 offers a unique solution to this problem with the
Amp parameter. All DSP 260 Factory Presets include limiter
threshold values. You may use the Amp parameter to select
the model of Dynacord 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-Dynacord 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.
