4. FIRST OPERATION

4.1 SWITCHING THE POWER ON

Using the POWER-switch (16) the DSP 244’s power is switched on. Upon initializing is complete, the last program that had been active before turning off the appliance is recalled. For now, the display shows:

Now, the DSP 244 is ready for operation. The display shows for instance:

Here, you have entered the factory preset program F01, which is an universal program for the 2-way operation. The configuration is stereo 2-way - the initial state of the DSP 244 when shipped from the factory. In case the appliance had been operated before, any other program might appear on the display.

For setting the DSP 244 in accordance to the configuration of your sound system, the best way to start is to select a factory preset program from the list that matches your actual system configuration (see chapter 7.1, PROGRAM SELECTION). You can copy this program to a user-definable preset and alter the settings according to your personal preferences (see chapter 7.4, STORE PROGRAMS AND PROGRAM NAMES, and chapter 7.2, EDITING).

4.2 LEVEL SETTINGS

To simultaneously achieve maximum headroom and minimal noise, the DSP 244 has to be properly integrated into the gain structure of the entire audio system.

You can set the desired input level of the DSP 244 using the two INPUT controls (1). Therefore, operate the system at the highest signal level that is to be expected in the further operation. Slowly turn the INPUT control (1) clockwise, while continuously monitoring the level meters (2) for peak readings. The optimal value for program peaks lies between -12dB and -6dB. The CLIP-LED’s indicate clipping of the AD-converter and should not light at all or at least only very briefly. When driving the DSP 244 below the mentioned range, its outstanding S/N ratio is not optimally used, resulting in probably audible system noise.
