The Remote Audio BDS (Battery Distribution System) has been the standard power management system in ENG audio bags for over a decade. Once considered a luxury, the ability to power multiple pieces of audio equipment with a single rechargeable battery is now a necessity as equipment demands become more complex.

The BDS system accommodates this need with a reliable, convenient, and robust design. The BDSv4u adds refinements such as a built-in 5V @ 2A (10W) regulated USB output for powering or charging compatible devices, a "low-battery" indication with three user-selectable thresholds, and an easily accessible "switched/unswitched" toggle.

Description

Remote Audio's BDS system consists of a reverse-polarity protected and overload protected distribution box with illuminated bi-color on/off switch, six outlets, power source (typically a rechargeable battery such as the NP-1), an input cable, and output cables for the devices being powered. The primary purpose of the BDS system is to simultaneously turn on and off multiple pieces of equipment being powered by a single source. For this basic function, the BDSv4u may be used exactly like the older BDS versions that it replaces. The input and output connections are the same, so all previous BDS input and output cables manufactured by Remote Audio are compatible with the toggle switch is in the on position, the RM/RS will not turn off the BDSv4u. In this case, the on/off function of the RM will only turn on and off the meter display.

The BDSv4u design takes the system to another level of functionality with the 6-pin connector for the RM (Remote Meter) & RS (Remote Switch) accessories. The RM & RS can turn on and off the BDSv3 remotely, and the RM can display the voltage of the power source and the amperage draw of the equipment. The BDSv4u can be used without the RM/RS. In this case, the toggle switch turns the unit on and off. Using the BDSv4u with the optional RM or RS When connected to the RM or RS, and the BDSv4u toggle switch is in the OFF position, the RM/RS controls the on/off circuit of the BDSv4u. This allows the BDSv4u box to be placed deep in the bag, out of the way. To turn the BDSv4u on or off with the RM/RS, flip the toggle on the RM/RS. When on, the RM will display the voltage of the power source. Pressing the lower button (labeled "AMPS") will display the current draw of the devices being powered for as long as the AMPS button is pressed. If the BDSv4u


Connectors and Cables

The outlet connectors on the BDS box are a special switching type that requires a long-shaft mating plug with a 2.5mm hole. This connector set was chosen for its strength and so that unused (exposed) outlets on the box are not active until a cable with the proper mating connector is plugged into it, helping prevent accidental short circuits. Output cables by Remote Audio are manufactured specifically for use with the BDS, and come with unique low-profile right angle locking connectors. Therefore, it is recommended that only Remote Audio brand output cables be used with the BDS system. The polarity of the outlets is "center positive". "Y" cables are available for connecting more than six devices. Input cables, battery adapters and AC-DC adapters by Remote Audio are also available.

The BDSv4u has a standard USB port to facilitate charging or powering anything that will run or charge via USB, such as a smartphone or handheld recorder. Unlike many other 12V to 5V USB adapters, which are limited to 1A, this USB port is able to deliver a regulated 5V at up to 2A (10W). The BDSv4u's USB the official USB "Dedicated Charging Port" specification. Devices that do not conform to that specification may not be able to take full advantage of the port's 2A capability. For instance, most Apple devices use a proprietary circuit to charge at the maximum rate (higher current). When connected to the BDSv4u, the iPad will show a "Not Charging" status message on the toolbar. In that case, it is being trickle-charged when awake and charged when sleeping or in standby mode, allowing the iPad to be run indefinitely (or until the BDS's power source is drained). This design choice was made to conserve battery life for more critical functions, such as powering the recorder/mixer in the bag. If faster charging for Apple devices is desired, we recommend using Remote Audio's BDSUSB adapter cable, rated for 1A @ 5V and containing Apple's proprietary circuit.

NOTE: When the USB port is at maximum capacity (2A @ 5V), it is important to remember that the 2A doesn't directly count against the 5A maximum total for the whole box, since they are defined at different voltages. It may be easier to think of it in terms of Watts. 2A @ 5V is equal to 10W (2 * 5), and the entire BDSv4u is limited to 60W (5A * 12V). So, the USB port can provide a maximum of 1/6th the total output of the BDSv4u, or the equivalent of ~833mA at 12V, not including the slight losses of the 5V regulator circuit.

For simplicity sake, if you're pulling a full 2A from the USB port, it is safe to assume that you've got about 4A remaining capacity for all the other output jacks, which is more than sufficient for nearly all ENG bag configurations.

The input connector on the BDS box is a common TA4M (miniature 4-pin male XLR) with the standard scheme of "pin-1 NEG, pin-4 POS". To improve reliability and reduce voltage drop, the contacts are doubled 1-2 and 3-4 at the circuit board. Therefore, if the user wires their own input cables, it is recommended to connect pins 1-2 and 3-4. The power indicator built into the BDS box switch can be used to confirm proper polarity of the input cable (if it illuminates, the polarity is correct).

Switched vs Unswitched Outlet

The indicated outlet can be either "switched" or "unswitched." "Switched" means that the outlet turns off and on when the main toggle switch is thrown. "Unswitched" means that the outlet is always on when power is present. The factory default for that outlet is "unswitched." 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 the outlet can be easily reversed to "switched" by sliding the nearby switch using a toothpick or jeweler's screwdriver. When using a metal tool to change the switch position, make sure the BDS is powered off to eliminate the possibility of shortcircuits.
