BARGRAPH DISPLAY BOARD
7-29-08 BOTH LENSES ARE BACK IN STOCK
THE
DS-1 BARGRAPH DISPLAY BOARD WAS DESIGNED PRIMARILY AS THE COMPANION DISPLAY MODULE FOR THE
WD7S TRIODE BOARD BUT CAN EASILY BE USED BY ITSELF. THE PRICE OF QUALITY ANALOG METERS HAS INCREASED TO
THE POINT OF MAKING BARGRAPH DISPLAYS AN ATTRACTIVE ALTERNATIVE. THE
DISPLAY BOARD IS AVAILABLE WITH A CHOICE OF COVER LENSES FOR USE WITH MEDIUM POWER (2.4KW),
OR HIGH POWER (4.8KW)
LINEAR AMPLIFIERS. THE BARGRAPH SCALES ARE ADJUSTED ACCORDINGLY.
ONLY ONE RECTANGULAR HOLE IS REQUIRED ON YOUR AMPLIFIER'S FRONT PANEL FOR ALL
METERING AND FAULT DISPLAY, MAKING PROFESSIONAL LOOKING RESULTS EASY, (SEE
THE GALLERY FOR AN EXAMPLE). ALL FIVE BARGRAPHS ARE FULLY ADJUSTABLE, EITHER ON THE BOARD OR ON ASSOCIATED
MODULES. WITH THE RAPID RESPONSE TIME OF THE BARGRAPH YOU KNOW WHAT IS
HAPPENING REAL TIME IN THE AMPLIFIER'S CIRCUITRY.
