Use the <SELECT> buttons to navigate between Active/Bypass, Delay and Unit. The values for each parameter can be
adjusted using the up/down VALUE arrows. The delay time or physical distance is displayed in milliseconds, micro-
seconds, feet, inches, meters, or centimeters.
O LEVEL
UTPUT
The output Level is used to adjust master output levels. To access the Channel Level screen, press the Level
button. Subsequent button presses will toggle the display between OUT 1 to OUT 6.
Use the <SELECT> button to navigate between the selectable Level (-100.0dB to +6.0dB), Polarity and Amp parameters.
Adjust the value by 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 DSP 600 offers a unique solution to this problem with the Amp parameter. All
DSP 600 Factory Presets include limiter threshold values. You may use the Amp parameter to select the model of DY-
NACORD amplifier that you are using and the limiter threshold offset will be automatically calculated based on the am-
plifier 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 "User" 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.
O LIMITERS
UTPUT
The DSP 600's output limiters prevent audio signals from exceeding a set level. Press the Level button to
change the output channel. Hold-down the Level button for some seconds - you will then be presented with
the Limiter screen.
LIMITERS
Use the < SELECT> buttons to navigate between Active/Bypass, Type, Threshold (-9.0 dBu to +21.0 dBu), Attack (0 ms
to 50 ms) and Release (10.0 ms to 1000.0 ms). Adjust the values of each parameter using the up/ down VALUE arrows.
The parameter Type allows selecting the used loudspeaker type. By selecting the type Sub, Lo, Mid or Hi the settings of
