Qualifying Tie Breakers - If 2 or more competitors tie during the qualification rounds of competition, and if 1 or more of those competitors is pushed out of the round of 8 while the other tied competitor(s) make the cut, then all of the competitors who are tied will be re-metered immediately prior to creating brackets. This procedure will only involve the original slots available in the round of 8 prior to the tie-breaking round(s). If all of the competitors who are tied make the cut, then re-qualifying is not necessary and placement in the elimination brackets will be automatically assigned by the computer.
Assume that 3 competitors tie with a score of 153.4 dB. On the leaderboard, the competitors are listed in 7th, 8th, and 9th place. To determine which two competitors will advance to the elimination rounds of competition, a tie-breaker will need to take place between these three competitors. All three competitors will be required to re-qualify. During this process, let's assume that the competitor in 7th place scores a 155.1, the competitor in 8th scores a 155.2, and the competitor in 9th scores a 156.1. This would result in the competitor in 9th place moving into the 7th place slot, the competitor in 8th place remaining in the 8th place slot, and the competitor who was originally in 7th moving into the 9th place slot. At this point, the brackets can be made and the elimination rounds can begin. There is one other situation that must be mentioned. Let's assume that the re-qualifying scores for the three competitors are ALL higher than the competitor who originally qualified for 6th place. The original competitor will NOT be displaced because only the 7th and 8th place slots in the round of eight were originally affected by the tie.
Elimination Round Tie Breakers - If 2 competitors tie during an elimination round, both competitors will be given 5 minutes to re-charge their batteries (alternators only ... no external battery chargers unless the venue prohibits vehicles from running inside the hall) and inspect their vehicles. Both vehicles must remain in the judging lanes during this time. The 5 minute time interval shall begin immediately upon confirmation of the tie. After the 5-minute time interval has elapsed the SPL meter will be started and the competitors will compete once more to determine the winner. This process shall be repeated until there is a winner.
All rules will be enforced based upon their intent and the ruling of the head judge is final.
Only the currently approved Term-LAB metering system may be used for judging purposes.
In rare situations electrical interference from the contestant's vehicle or sound system may prevent the Term-LAB measurement system from obtaining an accurate power measurement. In these situations the contestant will be moved to one of the unlimited power classes of competition.
Setup and Teardown Times at Multi-Point Events - Competitors may be required to setup and teardown within a specified period of time at multi-point events. The amount of time allocated for setup and teardown, and the penalty for exceeding these time limits will be specified by the show promoter prior to the beginning of the competition.
Setup time: 4 Minutes
Teardown time: 3 Minutes
Penalty: 1 dB for each minute in violation
