2. CONTROLS AND CONNECTIONS
2.1 FRONT PANEL
1, Control INPUT 1 / INPUT 2
Rotary controls to set the input levels of the inputs 1 and 2 of the DSP 244.
The input signal can be amplified by up to 6 dB (control set to its clockwise margin) or attenuated by any
degree. Set the level as high as possible without clipping to achieve the highest possible S/N ratio.
Checking your settings is possible via the reading of the two level meter instruments.
2, Level meters
The level meter instruments are meant for optical monitoring of the input signal levels, individually showing
the peak value of the correspondent input signal. The input control should be set to a position so that the
meter instruments indicate a level between -6 and -12 dB. To prevent internal clipping, make sure that
the clip-LEDs are not lit. Two different indication modes can be selected: “Peak Hold”-function or “Slow
Mode”.
3, Graphic display
In the PLAY mode this 122 x 32 dots LC-display shows the name of the program, its number, name and
description of the chosen loudspeaker systems, as well as the momentary active configuration. In EDIT
mode the display shows the function blocks including their individual parameters and parameter values.
Additionally and depending on the actually chosen mode, the display also indicates option menus, status
messages, short operational notes, etc.
4, EDIT-key
This key allows to enter the EDIT mode. After pressing the button, the first or the last modified parameter
of the active program is displayed. Other parameters are selected through the use of the SELECT-keys.
The individual value of the momentary displayed parameter can be altered by means of the rotary encoder.
For further information, please refer to chapter 7.2, “EDITING”.
5, SELECT-key <
While in EDIT mode, pressing the key selects the corresponding previous parameter. In the Option mode,
it is used to select the corresponding previous “Option Page” and in the Store mode, pressing this key
switches between program number and name editing.
6, SELECT-key >
While in EDIT mode, the key is used to select the corresponding next parameter. In the Option mode, it
serves to select the corresponding next “Option Page” and in the Store mode, pressing this key switches
between program number and name editing.
7, OPTION-key
The OPTION-key is used to enter the OPTION menu, allowing the user to alter and check appliance-re-
lated settings. For further details, please refer to chapter 9, “OPTION FUNCTIONS”.
