DC CONNECTIONS
24VDC power to the BGD is supplied by an external power supply. The power supply’s
DC output plugs into either mating receptacle on the rear of the unit. Plug polarity is
positive on the outside sleeve. The other DC receptacle is used to jumper power to
another unit sharing a single supply with available DC power cable loop-thru P/N
20602-1.
CALIBRATION
As shipped, BGD meters are set for nominal inputs at 0VU or 0dB of +4dBu. Internal
jumper plugs (JX04) for each channel allow nominal settings of -10, +4 or +8dBu to be
selected. To change the jumper plug position, remove the top cover by removing four
6-32 screws, move the jumper plug so that pins 1 and 2 are shorted together for +4dBu in,
pins 2 and 3 are shorted for +8dBu inputs or remove the jumper plug so that no pins are
shorted for -10dBu input (leave the plug mounted by one pin so that it doesn’t get lost or
rattle around). Put the top back on; if you lose the screws we have replacements.
