Meter Panel - Prism Sound ADA-8 Operation Manual

Prism Sound ADA-8 Multi-channel A/D D/A Converter Operation Manual - Revision 1.00

5.2 Meter Panel

The Meter Panel fulfils a few different channel-related functions. First and most importantly it
provides eight bargraph meters which can be switched to display the audio levels on all eight
channels of either Path through the ADA-8. Various peak-hold and overload modes can be
selected within the group of menus reached from the blue Access button. Note also that
numerical metering of the selected channel or channel pair is normally displayed on the Level
Screen (the 'home' screen of the Menu display).
The 'Path' selector button in the top left-hand corner of the panel assigns the panel's function
to either Path 1 or Path 2. Path 1 is usually the A-D Path, and Path 2 the D-A Path, in most
standard A-D/D-A configurations, but this is flexible. The 'Pre Post' button moves the
metering position before or after the signal Processing block of the selected Path.
The 'Hold' button enables or disables an indefinite bargraph peak-hold function, which also
affects the numerical meters on the 'home' screen of the menu display.
Below the bargraphs are a row of per-channel 'Alert' LEDs. These provide warning of various
notable conditions occuring on the corresponding channel of the selected Path. These
include digital input lock-status, analogue input overkiller action etc. The functions can be
multiply selected in the appropriate menu (also reached from the Meter Panel Access button)
so that the LED represents an 'OR' function of the selected functions.
The Channel Select buttons, and the 'All' button are used in conjunction with certain channel-
specific menus, as described in the Module Reference.
