Dynacord DSP 244 owner manual Compressor / Limiter Settings, Matching the Frequency Response

QUICK START

COMPRESSOR / LIMITER SETTINGS

A compressor / limiter automatically reduces level peaks above a certain threshold and therefore provides reliable protection against power amplifier clipping and damaging the connected loudspeaker systems. In most cases it is absolutely sufficient to set the compressor’s threshold to the modulation limit of the connected power amplifier.

Select the desired output channel in the Edit menu by pressing the corresponding OUTPUT control. Using the rotary encoder you can now select COMPRESSOR in the display. Now, the SELECT keys can be used to select individual parameters. Their values are altered through the use of the rotary encoder. Afterwards, use the left SELECT key to re-position the cursor to the function block in the top line.

Using the rotary encoder you are now able to select LIMITER in the display. Proceed in the same way as described for the compressor to make the limiter’s parameter settings for the selected channel.

Pressing another OUTPUT control selects the control’s corresponding output channel.

MATCHING THE FREQUENCY RESPONSE

Using the Master EQs in the input channels of the DSP 244, 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.

In the Edit menu, use the rotary encoder to select MASTER EQ1 in the display. Here you can adjust the first filter of the selected input. Using the right SELECT key, you are able to select the parameter “Type” and alter its setting through the use of the rotary encoder. Available are:

PEQ (parametric Peak-Dip-Filter)

LOSLV (Low Shelving Equalizer)

HISLV (High Shelving Equalizer)

LOPASS (Lo-Pass)

HIPASS (Hi-Pass)

All other parameters depend on the selected filter type. A complete overview is provided in chapter 8, PARAMETERS. Using the SELECT keys, you are able to select all parameters and alter their values through the use of the rotary encoder.

Afterwards, use the left SELECT key to re-position the cursor to the function block in the top line.

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.
