All other parameters depend on the selected filter type. The SELECT keys allow the selection of any parameter and the corresponding values are edited using the rotary encoder.
Using the rotary encoder you can now select next EQ sections to adjust its frequency response according to your liking.
Using the channel delays, it is possible to compensate construction-related delays of loudspeaker systems or delays that result from different positions of loudspeaker cabinets.
Nevertheless, herefore, it is necessary to know the distance between cabinets as precise as possible. Their values are altered through the use of the rotary encoder. Using the Master EQs in the input channels of the Dx 38, the PA-system can be easily matched to various environmental and acoustical conditions. In many cases, a graphic equalizer which normally is employed to perform this task is not needed any longer. Here you can adjust the first filter of the selected input.
Available are:. Using the SELECT keys, you are able to select all parameters and alter their values through the use of the rotary encoder. The rotary encoder can now be used to select another Master EQ to proceed with the shaping of the frequency response.
The rotary encoder also serves for selecting the second input channel. The Dx 38 offers 7 pre-defined configurations. A configuration is a basic setting that includes the routing of inputs and outputs, the function of the outputs Sub, Lo, Mid, Hi, Fullrange , as well as the kind and amount of parameters. These 7 configurations are:. If you do not want to use one of the pre-defined configurations, you have also the possibility to operate the Dx 38 in Full Edit mode.
Additionally, the output assignment output function - Sub, Lo, Mid, Hi, Fullrange is also freely definable.
The active configuration is defined by the selected program; i. In general, all configurations offer identical signal processing blocks. Five filters are available for either one of the two input signals. In the following chapters you will find a more detailed description of the different configurations. This configuration generally represents a 2-way stereo frequency crossover, where IN 1 serves as the left input channel and IN 2 as the right input channel.
The parameters of the inputs 1 and 2 as well as the ones of the Low-range and High-range outputs are always set to identical values; i. This configuration represents a 2-way frequency crossover with monaural sub-channel and additional Fullrange output. For example, this output signal can be used to provide sound reinforcement in adjacent rooms. The parameters of the inputs 1 and 2 as well as the ones of the two High-range outputs are always set to identical values; i.
The figure on the right bottom shows a typical configuration with monaural sub woofer and additional Fullrange installation. OUT 4 can be used for example for monitoring, delayed full range-systems or to provide separate sound reinforcement in adjacent rooms. Two Dx 38s are necessary for stereo operation.
This configuration also represents a 3-way frequency crossover with additional full range output, with the difference that the Sub-range channel OUT 1 is fed by the summed mono signal of the inputs IN 1 and IN 2. The outputs OUT OUT 4 get their signal-feed from the input channel IN 1. OUT 4 can be used for instance for monitoring, delayed full range-systems or to provide separate sound reinforcement in adjacent rooms.
An example of a typical system configuration for this structure is shown next to the diagram. As well as the two previous configurations, this configuration also represents a 3-way frequency crossover with additional full range output, with the difference that the Sub-range channel OUT 1 gets its signal-feed from the input channel IN 2.
Thus, it is independent from the other output channels. The audio signal for the outputs OUT OUT 4 is fed from the input channel IN 1. The 4-Way configuration is a monaural 4-way frequency x-over. All outputs are fed by the input channel IN 1. The internal structure of the 4-Way configuration is shown in the following signal flow diagram. An example of a typical system configuration for this structure is shown in the figure on the right bottom.

Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
Use of a mains separator transformer is mandatory during maintenance while the appliance is opened, needs to be operated and is connected to the mains 3. For now, the display shows: Now, the Dx 38 is ready for operation.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintance servicing instructions in the Page 10 Page 13 Service Programs The Dx 38 provides several onboard service programs that allow testing internal function blocks. If no error has been detected, the display shows ' OK '. If a faulty condition has been detected, the corresponding address or respectively the erroneously read data appear on the display.
Page 15 Upon re-start the appliance is set to the factory program F CAUTION: To prevent the total loss of user-defined data, previously backing-up the contents of the user preset memory, using the Dx 38 editor software, onto a PC or notebook computer is strongly recommended.
Page Encoder Type This program allows setting the appliance to the employed type of encoder. Changing the encoder type is only necessary when older models with serial numbers up to Dx 38 are updated to a new operating system V1. When shipped, the appliance is always correctly factory-set, matching the employed encoder type. Page 31 Pos. Part No. Page 32 Pos.
