Low Battery Indicator
The illuminated toggle switch is a bi-color type that
indicates when your power source (typically a
battery) falls below a certain voltage level. This
threshold voltage is selectable via a switch on the
face of the BDSv4.
When the battery voltage falls below the selected
threshold, the illuminated toggle will switch from
Green to Red. Battery voltage is influenced by the
current draw of connected devices, so some
experimentation may be needed to find the correct
threshold for your setup.
Short Circuit and Overload Protection
The BDS box has auto-resetting protection against
output short circuits and loads in excess of 5A @
12V (60W), with each outlet capable of handling up
to 3A. If the BDS fails to pass power, it could be due
to an overload or short circuit. In the case of a short
circuit of an individual output cable or piece of gear,
only that outlet's breaker will trip, protecting the
other connected gear from damage. If a piece of
gear fails to power up, that output cable should be
checked for continuity with a multimeter (shorted or
open conductors), or replaced entirely. The BDS box
will also protect itself when connected to loads of
over 5A, and the on/off toggle switch will no longer
be illuminated. However, it is very rare for field
audio bags (the primary intended use for the BDS)
to have current draws in excess of 5A.
Reverse Polarity Protection
As a protective feature for devices being powered, in
the event that an input cable or battery adapter is
miswired, the BDSv4 will not pass reverse polarity
voltage to its outputs. Unlike some reverse polarity
protection circuits, the BDS circuit does not cause a
voltage drop during normal operation.
Noise and Shared Power Systems.
Thousands of satisfied field audio professionals are
using the BDS system to power their equipment.
However, it is possible to have unwanted audible
noise induced into audio systems by a common
(shared) power source. To optimize your system, it is
recommended to use line level signals instead of mic
level signals whenever practical. Also, turn phantom
voltage off of all preamp inputs that are connected to
non-microphone devices. If noise is still heard, to
determine the cause, unplug one device at a time
from the BDS box, noticing any change in noise
associated with the removal of each device. If the
noise goes away after unplugging a particular
device, try powering that device with a separate
battery. If using a separate battery causes the noise
to go away, then the problem is a ground loop
associated with the combination of a common power
source and audio grounding schemes. Be aware that
this noise will not be removed with "LC" filters found
in some distribution boxes. To remove the noise,
here are four options for interrupting the ground loop:
1) Use a separate battery for the offending device. 2)
Try different grounding/floating schemes with the
audio cables. 3) In devices that use a single 9V
battery, use an isolating 9V battery eliminator such
as those made by Lectrosonics. 4) Use a power
isolator cable such as the Remote Audio Juicer
cable.
Mounting Clip
The BDSv4 box comes with a stainless steel clip to
aid in securing the box to a bag or strap. NOTE:
Keep the original clip screws. Attaching the clip with
screws longer than those originally supplied can
damage the BDS box and void the warranty.
