Selecting Average Response on BargraphsSelecting Average Response on Bargraphs
The Bargraph Meters on your SPIRIT STUDIO are capa-
ble of two modes of operation: PEAK and AVERAGE.
In Peak mode the meter responds rapidly to initial sig-
nal transients and decays slowly, making it easy to
detect overload. In Average mode the bargraph takes
on the characteristics of a VU meter with evenly fast at-
tack and decay times. All meters are factory-set to
PEAK characteristic, but may be changed to AVERAGE
response by moving a link from PeaK to AVErage posi-
tions on the appropriate PCB as shown below. To
select AVERAGE response, remove the PCB from the
console and carefully unsolder the link in the PK posi-
tion using the minimum of heat to avoid the possibility
of tracks lifting on the PCB. Replace the link in the AVE
position.
This operation should only be carried out by competent
technicians who possess the necessary soldering
skills.
