Remote Technologies BDSV3 manual Orange ring… Switch vs Unswitched, Reverse polarity protection

BDSv3 / BDSv3 - N

The orange ring… Switch vs Unswitched.

Outlet #1 can be either "switched" or "unswitched". "Switched" means that the outlet turns off and on. "Unswitched" means that the outlet is always on when power is present. The factory default for outlet #1 is "unswitched", as indicated by an orange ring. This feature is often desired for the audio mixer. For example, in this configuration, when only the mixer and boom mic are needed, turning off the BDS box will turn everything off (receivers, etc.) except for the mixer.

This can be a convenient way to turn off everything that is not needed, extending the life of the battery. The status of outlet #1 can be easily reversed to "switched" by opening the BDS box and moving a jumper from the unswitched position to the switched position as labeled on the circuit board. No soldering is required to make this change. Care must be taken to not over-tighten the outlet connector nut when replacing the orange ring.

Short circuit and overload protection

The BDS box has auto-
resetting		protection		against		5A global maximum
output short circuits and loads
in excess of 5 amps, with each
outlet capable of handling up
to 3 amps each. If the BDS
fails to pass power, it could be						3A	3A
due to an overload or a short
circuit.	In the case of a short					3A
circuit of an individual output							3A
cable	or	piece	of gear,		only	3A
that outlet's breaker will					trip,		3A
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 5 amps, 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 5 amps. Using the optional RM (Remote Meter) with the BDSv3 will take the guesswork out of calculating the amperage draw of your system.

Reverse polarity protection

As a protective feature for devices being powered, in the event that an input cable or battery adapter is miswired, the BDSv3 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 "L/C" 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 made by Lectrosonics (isolating AA eliminators should soon be available). 4) Use a power isolator cable such as the Remote Audio Juicer cable (30 watts max, but a bit large for bag use).

Mounting clip

The BDSv3 box comes with a stainless steel clip to aid in securing the box to a bag or strap. Additional holes on the box are available for positioning the clip in the opposite direction. 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.
