Just wanted to jump in here and add/correct a few things... The speakers ARE magnetically shielded. Same as the original SpeakEasy. Actual weight is 2.6 lbs. Dimensions: 19 x 1.75 x 4.25 inches Idle power drain: 55mA @ 12VDC Power Output: 7.5W per channel @ 8 Ohm nominal speaker impedance Maximum SPL: 92dB (1kHz @ 1m)

For a long time we had a SpeakEasy here in the shop with an oscillating amplifier that did what you're describing. We kept it around for a while, firing it up during certain situations. Maybe I'll put a hidden "PTF" switch on the next version.

Just to correct and add a couple of things... The BDSv3 does not have a flashing LED indicator for reverse polarity. That is present on our Shunt Box, but there is physically not enough room on the BDSv3 circuit board to implement it there. Glen really wanted me to get it in there, but it would have made the box's footprint slightly bigger. The reverse-polarity protection of the BDSv3 applies to the input (the TA4 connector) and will protect all of the outputs from seeing that reversed polarity, whether switched or unswitched. If a reverse-polarity condition at the input is detected, a reverse-biased diode across the input will shunt all the current through the master 6 Amp breaker. The breaker will trip, and no voltage will pass to the outputs. This is different than the method used on some other distribution systems in which a diode is wired inline at the input. That method will decrease your usable voltage by about .7 Volts due to typical diode forward-voltage drop. There's no way to protect against a reverse-wired output cable, however. In fact, I know of a few pieces of gear in our industry that require a reversed output cable (i.e. center pin negative). Shure FP32, Wendt X2 & X4, PSC M3 & M4 immediately come to mind. As of mid-April, the most recent revisions of the BDSv3 have individual 3 Amp breakers on every output, including the unswitched one. This is a change from previous BDS versions in that a short at any output will not cause the master breaker to trip and shut off the whole box. If you have a problem with one piece of gear or cable, the rest of your rig will still function. The box is still limited to a global maximum of 6 Amps. Hopefully that clears a few things up.
