Speaker Testing

The primary goal of speaker testing is to weed out broken speakers and pair working speakers with thier appropriate power bricks to send off to the Build_Workshop.

Quick Guide

• Find a pair of matching speakers on the shelf.
• Look on the back of the main speaker and try to find power information.
  • If you find power information (voltage and maybe amperage), select a power brick that matches.
  • If you cannot find power information, take one of the tester bricks (should be in one of the outlets) and go through until you get a plug to fit. If the plug is still not the right voltage or amperage for the speakers, a buzzing sound will happen when you turn the speakers on.
• Once you have paired a power brick with matching speakers, plug the speakers into the stereo headphone jack and plug the power brick into the outlet. Tune into your favorite radio station and see if everything sounds right.
• If the sound isn't distorted, put a matching gizmo id on each speaker and the power brick if there is one. Bag them up and put them in a basket to take back to the Build_Workshop.

Power Brick Sorting

We get a lot of power bricks in reciving and most of them all look the same. If they are simply dumped into bins unorganized, it can take quite a long time to find the right brick for a pair of speakers. One of the tasks of reciving / speaker testing is sorting power bricks into proper voltage bins. Once the bricks are in the right bins, speaker testing can process speakers much faster.

Currently we have four different organized bins. This system probably needs to be revised as we see how many bricks of a specific voltage we get (there may not be enough 6 volt bricks to justify a separate bin). One possibility is to have a bin for "Under 10 volts" another bin for "above 20 volts" etc.

Current Bins

• 6 Volt AC/DC
• 9 Volt AC/DC
• 12 Volt AC/DC
• 15 Volt AC/DC
