4.1: MASTER CONTROL PANEL
When the PCAP II Plus Master Control program is run from Microsoft Windows, the Master Control
Panel appears. The Master Control Panel features are shown in
Figure 4-1.
From this screen, all audio processing capabilities can be accessed. The Master Control Panel is
organized logically from left to right, with audio input controls at the far left, digital signal processing
controls in the middle, and audio output controls at the far right. Master Control functions are as
follows:
Title Bar Used to “drag” the Master Control window to the desired area of
the display. Also indicates the filename for any .DAC setup file
currently in use; see Section 4.10: for further details on filter setup
files.
Menu Bar Used to access the Master Control pulldown menus that allow
saving and opening of filter setups from disk files, configuring
RS232 communication with the external processor, storing filter
setups in nonvolatile memories inside the external processor for
Stand-Alone operation, generating hardcopy setup reports, and
getting online help. See Section 4.10: for further details on these
features.
Input Levels Box Used to view input signal levels via bargraph display, adjust
input levels via slider controls if desired, Configure the Input
HPF stage and toggle its Active status, and Configure the
input Limiter stage and toggle its Active status. Also, in the
case where the DIGITAL input is used, the status of the
channel swapping feature is indicated just above the bargraphs;
see Section 4.10: for further details on these features.
Configuration
Box*
Used to select the System Bandwidth for the external processor
which most closely matches that of the input signals (physically
adjusts the processing sampling rate of the PCAP II Plus). For
speech processing applications, settings of 3.2kHz to 6.5kHz work
best. For wider bandwidth applications, 8.0kHz to 16kHz is
recommended. Also, allows specifying the Input Mode; Mono
allows the user to enhance a single input signal (Left channel only)
with as many as 12 successive stages of signal processing. Stereo,
Linked allows the user to process two input signals
