Dig In Lvl Dig In Lvl is a master control for digital inputs. Select Off or a value from -89dB
to +6dB to optimize the level of the digital input signal.
When digital input is connected to the MPX 1 and Dig/Ext is selected in the
Input/Clck menu, the ChanStatus menu allows you to determine whether or not
Channel Status information received via the MPX 1 digital input is transmitted
unchanged through the MPX 1 or whether the MPX 1 is to generate its own
Channel Status data. The available selections are: Pass thru and Generate CS.
(If Analog/Int or Analog/Ext is selected in the Input/Clck menu, the display will
show Generate CS without the option of another selection.)
The Soft Sat control puts an analog soft-knee limiter in front of the input of the
MPX 1 A/D converter. This control essentially allows you to trade the harshness
of digital distortion for a softer, analog version. The harshness associated with
A/D overload at signal levels above -3dBfs is reduced. Increased analog
distortion will occur in the range of -3dBfs to 0dBfs. The available settings are
On and Off.
The MPX 1 Modes menu allows you to specify certain system-wide parameters
and modes of operation for convenience. Each of these is described in this
section.
Pgm Load allows you to choose whether programs will be loaded manually or
automatically.
Selecting Manual allows you to scroll through programs in Program mode,
viewing them according to the DataBase criteria you've selected. Programs
which are not loaded are identified by an asterisk (
✱ ) preceding the displayed
name, and flashing of the Program button LED. Press Program to load the
displayed program.
Selecting Auto (the default setting) will cause programs to be loaded automati-
cally following a brief timeout whenever they are selected in Program mode.
